Z probe offset not working

z probe offset not working Mesur" in the G54 work offset. The BLTouch won't function reliably if the pin is dirty or damaged. And yea, looks like your nozzle is too low compared to your probe for some reason . The easiest way to get the Z offset value is to: Home the Z axis. Keep in mind that auto-leveling process is primarily controlled by the firmware, so the exact locations where the probe moves to are already pre-defined on the machine. Using the command M666 X0. 1 does not work, try Z-0. G38. 5142 y -0. Run through the Z axis checks that are outlined on page 24 of this guide. The Z-axis offset, or Z-offset for short, is the distance from the top of the heated bed washers (defined as “zero”) to the tip of the hot end nozzle. z In environments where there is a danger of any liquid being spilled on the probe. It uses the same Z-min inputs, i have the touch-plate wires and the Z probe limit sw wires in parallel, they both trigger the same Z-min input. 0. This will deploy the probe (if applicable) and start the head descending or the bed rising. 7 Delta with Duet-WiFi, FW: 1. . error(localize("Z must be enabled by setting the 'useZ' property to use drilling cycles. Click "Measure Offset Z" again to release it and restore normal mode. M212 Z0 or M212 Z-. I'm using a Prusa clone with Ramps 1. Mach3 Zero Probe Tool: This is a Simple Guide on how to use a Probe Tool in Mach 3 to find the exact top of a material. I decided to make something with offset X=0, Y=0. 2 => -5. 3. Move the axis over the sensor and zero all. For example, if the switch trips when the platform is 3 mm below the nozzle, you set the Z offset to +3. 03mm: leveling-strategy. 4 G1 Z0; brings nozzle down from 0. 72 would offset the X1 stepper 0. 2. #define USE_PROBE_FOR_Z_HOMING #define Z_MIN_PROBE_PIN PC4. Thingiverse is a universe of things. 5mm, but cannot be moved at Z=000. This work-offset allows us to define a relative position anywhere on the table to cut our parts. 2 to the z height in Cura, is there a way to do this ?, there used to be a setting which indicat There will be number that represents your current z-offset. Adjust the Z offset - once you get the z probe set up in general - use a negative offset (such as -1 or -2, -3. But, if you wind up needing to remeasure and reset the Z Probe offset after you change out a bit, then you should consider adding wiring for a touch-plate and use the G30 command. then it comes back up, not ever getting to the probe, it stops and goes back down to the next probe point. Turns out offsets don’t work unless you relevel the bed, You have to do another probe to “apply” it. Clear the current Z axis home offset by sending g-code M206 Z0 through the terminal; we set the Z axis home offset to zero. 222, or 208. Touching work surface with tool is a great way to break a tool. I decided to upgrade to the Hero Me system while maintaining all the original CR-10S cooling fans. Make sure your homing macros use G30 to home Z and not a G1 S1 Z movement. The nozzle should touch the bed. 4. 0; sometimes CraftWare 1. NOTE this is NOT supported for deltas, use on Cartesians only. Go to Motion > Move Axis > Move Z. 4 in Marlin firmware 1. 72mm away from it’s endstop, Y! can also be used. To start off with, if you are a bit short of time – here is the most useful tips I have that will prevent most of these common issues. So, restore the settings to failsafe! Get the best deals for wood smoker grill at eBay. 222. even if its correct try to lower it by lets say 20 to 30 mm. * But: `M851 Z+1` with a CLEARANCE of 2 => 2mm from bed to nozzle. #define Z_PROBE_OFFSET Reboot and it should not work, since WinCal would pick up the newer Velox 2. So my first try at the focus test with the 9. " The connections to the USB interface is as follows: - The spindle is connected to the gnd terminal (which is also connected to the end mill). Tweaked the Z-offset and Probe offset values in the EEPROM until the bead was close enough to the nozzle to be able to do a fine tuning; ran a test print and the print bed crashed into the nozzle poking a crater on the I manually set the z-offset and I'm in the middle of a print so at least I can manually set it. Rotate PINDA body to wire is toward back (it is not centered). . h. 25 (rapid close to switch) M8 (turn on coolant to blast chips away) G1 Z0. 2 address does not work then try another public IP like 4. 001) but it only gives me the option to adjust by 1/10 (0. 19mm. If you notice the stored mesh is not working as well anymore then get a new mesh. Z - Z offset probe to nozzle. 5 Znnn where nnn is your Z-probe offset. In the image above, we are looking down on the table along the Z-Axis. 2. The best way to do this is to take the other end of the Z Probe not connected to the board, and bring it around and to the left of your CNC. 15 (or higher) no matter how much Z offset I G30 Znnn will probe until it hits the bed then sets Z to nnn, this can be used to set the nozzle height if nnn is the probes Z offset from the nozzle in the Z direction. If you are using an adapter and/or extension cord make sure they are also grounded. M851 Z-0. dwell == 0) ? 0 : clamp(1, cycle. 45mm for the next steps. 220. 67. Prusa Marlin fork (Prusa-Firmware 3. A better solution is turning on baby stepping and making it be the same as z probe offset :) Marlin told me a Z offset of -1. #define SENSOR_LEFT 0 #define SENSOR_RIGHT 0 #define SENSOR_FRONT 0 #define SENSOR_BEHIND 50 Finally set the bed extra movement. I use them in my Auto Zero macro, to set the Z axis the same regardless of the current offset. The purpose of using a reference tool, is that any other tool will get a tool length offset (TLO in the readout) with a non-zero value in relation to this. 2605 d 0. There is no offset X. For installation instructions for both the work probe and tool probe refer to The only tricky part is your z-axis origin. 1) Add the TMC3in1 plugins to your "C:\Mach4Hobby\Plugins" folder, open Mach4 menu -> Configure -> Control -> Plugins, and disable the TMC3in1 plugin there, or. I'm still not sure this would throw the print position off but it wont help the bed levelling. 15mm with the G31 Z-0. I'm no expert with g code, but could you not just set up a "work offset" in mach3 for your required position, ref all, then goto zero position in the required offset. Use File:Hollow10. It might be a good idea to write down this value. 2-1 stable and flashed it. I guess you have not homing order XYPreheat Z with z probe pos at 100,100 so activating at that position works. This process makes it easy for the cnc machinist to see and alter only those tool and work offsets which are actually being used in the cnc program. Once you set the parameters a few times it’s like second nature. . Using the command M666 X0. Take the current Z value and negate it. 15 but that wasn't enough, so to move back more, subtract 0. 1-mm offset in reality. The unfortunately designated M666 lets you test your offset to quickly calibrate your machine. First home the machine. Check the Z position on the printer screen, and subtract another 0. 3. lightProbeProxyVolumeOverride: If set, the Renderer will use the Light Probe Proxy Volume component attached to the source GameObject. Check your Z endstop trigger: EZABL – Z Not Showing “TRIGGERED” M119 Test Use G30 to Home Z. When printing if you are getting it starting too high or too low press the printer menu button 2 times while printing and it will bring up the “Probe Z Offset” menu. 2. You are using M53. Remember to M500 to save it . Z probe offset not working obviously. If you’re not familiar with the electrical components of a pellet grill it’s not really that complicated. If Z-0. x and v2. If X and Y are not 0 then someone answered NO at some point. firm files I dont know how to change the settings for the probe offset. Check if the mach3 start signal is right; 4. 4. Make sure that the speed not 0 now, if it is 0, Please input 10000 of spindle speed, and Enter. Stock Marlin v1. This will locate the ring in the measurement range. G28; home axis = works G29; auto level = works G28; it goes to home and then sets Z to 0. x. 14 or Cura 2. When you stop a program and then run from line the Z makes a straight down Z move till the probe triggers, but no error code is generated, and then goes to the line requested location without lifting. I tried dialing it in as it was printing yet the head does not adjust. h. The Z-axis offset, or Z-offset for short, is the distance from the top of the heated bed washers (defined as “zero”) to the tip of the hot end nozzle. What this says is that the Z probe height is longer than the desired Z height so you need to make it shorter. Note that other versions may not work. In addition to that be sure you followed ALL the steps of the installation guide (especially the sensor calibration, Z offset, and the slicer settings (starting code is essential, use the one in the guide)). An example of this would be -1. #define Z_PROBE_OFFSET_FROM_EXTRUDER 2. 0. 1. 11 software did not work because I did not have the Enable Z Axis switch turned on. There is also another coordinate drawn as G5X. e. I am going to try teeking the probe z-offset before the ABL. Mine is at -1. 5" this will raise the Z offset to 0. * (retract Z to safe level) G129 (set Tool probe Work Offset) M5 (make sure spindle is stopped) M9 (turn off coolant) G0 X0. Not much more programming. Write the following command or record as a macro to set the offset for the Z Axis. Must be different. G28 (Home XYZ) (Move Z at least 30mm away from the bed if it's not, and attach probe if you have a removable probe) G32 ( Probe the grid ) (Remove probe if you have a removable probe) M500 (to save probe results) G28 (Home XYZ) (jog down to touch the plate) M306 Z0 M500 (to save homing offset) G28 (Machine is now grid-levelled and knows it's Once the operation of the Z Probe has been tested the sequence can be run again with the block in position on the work surface. For those who are not familiar, the Hero Me is designed to be modular system and once a base has been designed for your printer, you can bolt on any configuration of Z probes and cooling fans. 0 flash, the z-probe offset is set to zero. Setting up Marlin. 2879 stddev 0 Your probe is a straight Z down move. M851. First actuate the handle for manual pulse feed to move the axis back in the opposite direction to the zero-point, and then carry out the zero-point returning operation once again. Second of all, I do not completely understand what the M119 command is supposed to give me. Now press the tool probe button from the main screen. G92 Z19. Getting the Probe Thickness/Height: The only thing that requires a calibration is the Z-probe offset. 9j. Just need a value there, and one that will be easy to do math with later. 1 mm in the Z-axis. 72 would offset the X1 stepper 0. Or use same thickness material off the piece. lightProbeUsage: The light probe interpolation type. Y between the probe and the torch tip. G1 F60 Z0 - Move nozzle to true 0 offset M211 S0 - Switch off soft endstops (Important otherwise Z does not change) Move nozzle towards bed slowly until the paper can barely move Take note of the Z on the printer display (take that number and add the measurment of the calibration sheet or device used) If anything does not work, hit the small reset button on the controller or unplug the power. 35mm (Z dime offset) = Z offset. OTOH there are a few printers that use the Z probe for X homing. Hold a suitable surface below the print head to trigger the Z probe. Ensure there is nothing below the torch then jog the Z axis down until it stops at the Z axis MIN_LIMIT then click Touch Off with the Z axis selected to set the Z axis at zero offset. All 3D printers are tested before shipping so you can order today with confidence. If i then Zero the second Z axis (A) the original value stays linked to the original Z. as long as your [bltouch] settings are correct, the BLTouch pin should engage, and the Z axis should lower and stop, once its triggered. Currently the correction values A/B/C correspond to z probe positions 1/2/3. 2) Open your "C:\Mach4Hobby\Profiles\YOUR PROFILE NAME\Machine. Follow these steps to change your Z-offset. */ # define Z_CLEARANCE_DEPLOY_PROBE 10 // Z Clearance for Deploy/Stow Note that a probe’s zone is aligned to the main world axes (X, Y and Z) and can’t be rotated. The method for using the probe is as follows - 1 - Set your x and y offsets on the job. This will be your new Z-Probe Offset value; Set the nozzle temperature back to 0 with M104 S0; Set your new Z-Probe Offset using M851 Z<newValue>, for example M851 Z-2. If your glass is that thick and the probe sensing range is not enough to achieve the proper mechanical setup and spacing here, then sorry, it just Repetier-Firmware configuration tool for version 1. 2 Z-100 This will not work on a glass bed. 65 / Z offset: -below +above [the nozzle] Could not make the dual z work, tried lots of things 2. 3 for auto-leveling with a fix mounted sensor connected to the Z end-stop pin. 5, etc) to get the nozzle down all the way to the bed for printing. 94 Once you have this number entered, you will need to go up 2 menus to the Control Menu and scroll down and click "Store Settings" to save the new offset. To me it seems that it doesn’t make a difference. 2 fix 2 using the Anet Sensor version of the configuration. 220. g. Get the average of the three points and then add 0. 002” 2. Changing the Z offset allows you to fine-tune the Z=0 position by exact values, not putzing with a mechanical setting that can make things worse. 5 height, and tool 30 at 4 height. When you post process you set “use z axis” to yes, pierce height and probe offset, just like you would your delay. Latest dev now tests for succes on repositioning. The probe should actually be < 1mm higher than the tip of the extruder. We have a great online selection at the lowest prices with Fast & Free shipping on many items! To make this easy I have a model of my table with the MCS origin in Fusion 360. the G32 S2 will take care of z-height and will correct it to the right one. Personally, I've noticed that using M581 to change the offset does not actually work with G29, even after M500 and M503 to verify, it still uses the default Z_PROBE_OFFSET_FROM_EXTRUDER offset regardless of what you set it to. Its the same procedure i've successfully run from aspire, but it does not seem to work from 360. probe_offsets: 0,0,0: The probe offset from nozzle, must be X,Y,Z, default is no offset. See full list on repetier. Due to TPU's higher elasticity, with a typical (PLA) Z offset TPU can compress at the nozzle when first loading and seal the nozzle creating enough pressure to render the extruder ineffective leading typically to an extruder jam - not fun with flex materials. I think I've figured it out, at least why the Z offset is not working : I think the printer is not accepting negative values for the Z axis as of now. Probe triggered early is a result of z height after probing though. Download files and build them with your 3D printer, laser cutter, or CNC. feedrate; var P = (cycle. 4 is -3. 1. After this you can just take a newly installed tool, jog to this freshly cut face, touch it and hit the same "Z Offs. So I found the switch (under device setting) and turned // the build plate and then put those as NEGATIVE values below, positive values will NOT work (move your endstops to fix a positve offset). Bending correction adds a value to a measured z-probe value. Or use a straight edge across the piece and calculate the offset. With the printer off, turn the Z motors clockwise and carefully lower the nozzle. Once you have G54 through G57 set to the four vise jaw positions, you’re ready to go. 3. But zmin overloaded as both zmin and probe does not work with G38. Set the XYZ distance from the nozzle to the probe trigger-point. . Using RCBugFix from about 12 hours ago. 9. Go to Control > bed levelling> Probe Z Offset > [use the dial to select the desired offset] Go back and select 'Store settings' (scroll down to find it) and once more Go back and select 'Store settings' (scroll down to find it) Got to Control > bed levelling> Bed level The Sensor will be replace the Z switch. By default, a probe’s zone of effect is centred on its view point but this may not be the ideal position for capturing the reflection cubemap. Disable stepper motors using the LCD menu command. // M401 - Lower z-probe if present // M402 - Raise z-probe if present // M404 - N<dia in mm> Enter the nominal filament width (3mm, 1. Look for the input signal for the switch on the screen. 4 to 0, so this works also. Also note that the sensor may have a hysteresis, the trigger depth may be different from the release point, set the z offset with a sheet of normal printer paper after g29. With the printer off, turn the Z motors clockwise and carefully lower the nozzle. If no steppers are specified, this command enables all steppers immediately. To adjust the z-offset you will probably need to go lower than z=0, so disable the Software endstops by putting two // in front of them. The BLTouch has 2 connections; the first is done through a pin 27 connector and is just unplug the LCD cable, plug in the connector, plug in the LCD again and attach the 3 wires from the BLTouch making sure the orientation was correct by verifying the labeled pins were attached to the correct, color coded wires. OFS Meas Uses Work; 65 – Graph Scale (Height) 66 – Graphics X Offset; 68 – Graphics Z Offset; 69 – DPRNT Leading Spaces; 70 – DPRNT Open/Clos DCode; 72 Assign tags to your config file so you can find it later with the search function. . – Made the default memory to 50 Mpt. NO, you need SOME offset so that when the nozzle really is close to the bed, the probe is already triggered and in the constant triggered space, but not so low that it could interfere with the print. You've already told the firmware to move -. three-point-leveling. Z Leadscrew needs Lubrication If the above fixes do not work try adding lubrication to the leadscrew from top to bottom. We also need to examine “MIN_PROBE_EDGE 10”. 11. Note that you'll have to close the Pronterface UI while doing the firmware upload. 72mm away from it’s endstop, Y! can also be used. and then try to probe it (dont know if its a typing fault but the command is G32 S2). I should need something so when i Zero Z ands swap axis (A becomes Z) the Zero value for the Z gets saved onto the axis i've zeroed. Note the Z axis value on the display it should be something like -1. Lulzbot Cura is used to generate printing files for untethered operation or to control the printer via USB for tethered operation. You seem to z probe at 0,0 and this needs to move into negative coordinates to activate z probe and that would not work according to your settings. 5 and an inductive proximity sensor Z-probe. Done and start printing! Again, it’s very important to heat up nozzle to 180-200 while using Z-offset Tool (if there is PLA in nozzle) Else the Z-offset will vary a lot depending on the leftover material stuck on nozzle tip. Do not operate the probe: z In the presence of noxious, corrosive, or flammable fumes, gases, vapors, chemicals, or finely-divided particulates. 1. Then for the probing routine setup I select offset "6" which is G59, and the probe will write to G54 by default. 09. You can also use your ISP provided ones as well. The Z position should now be aligned when the head stops. Then again, adding one isn’t that expensive, and then the whole process is automated. #9 ballhogjoni , Mar 24, 2020 Z Offset Set-Up. Z-correction (distortion correction) Sometimes it is hard to calibrate your delta printer in such a way that the bed is even - even if it is even. Ideally, you should have the Mesh adjusted for a Mean Height of 0. 3000 tip1 meas x -55. Setting the probe scaling incorrectly is a common error, and throws the reading off by a factor of 10. Needs Marlin firmware with z probe capability enabled. 0006 Released Date: 16 April 2015 Operating System: Windows 7 Bug Fixes – Made updates to the “Quick Environmental” cal for the 90000 (Q, X, V and Z) series. next time around, if I run the job again, the Z offset is greater. This is my second approach to z-probe for my Kossel Mini. The WIPS work probe (P/N 60-0050) has a round Haas logo. 2) Send command G30 to do a single Z probe. Go to Prepare / Delta Calibration / Delta Settings, and adjust the Height setting by SUBTRACTING the Z offset you noted. Go back to the main screen. Also verify the X1 corresponds to the X1 stepper. 1- V1. 5. 75mm ) or will display nominal filament width without parameters // M405 - Turn on Filament Sensor extrusion control. There is an option in settings to set the live z-offset - found it more useful to set it and run the calibration. I kept my finger on the power button at this point to stop the hotend from crashing into the bed if need be. Hi, I have allready tried, but I did not find a solution. Add input to the control view for editing the z probe offset on marlin based printers. Enabled EEPROM and CHIT CHAT within firmware. ) How do you do this or is there a way to do this in PC-Dmis? Thanks for you help. First I made z-probe with "big" offset X=30 Y=-25 and it did not work well for my delta. Use and edge finder or probe to locate the position of that vise jaw corner and then set that work offset based on the way your machine controller sets up offsets. (go to switch) G0 Z. Raise the screw by roughly the same amount of the distance between the nozzle tip and the print surface. 2 (I tried P0 and P! and it did not work) but maybe it is not correct at all. We have a bunch of new stuff to share. cfg and change the z_offset to 10 in the [bltouch] section. 2 - Set tool to tool 0 - this is where the Z0 offset for the job is stored 3 - Jog the tool (any tool) over the job. bin" has not been posted, what changes would I need to make when building Marlin in order to be able to use the Pin 27 Board If you know the Z offset at this point (for instance, if you've set up the probe on your printer before and have experimentally found the offset) then you can configure it here: #define Z_PROBE_OFFSET_FROM_EXTRUDER -1. Move the cursor to the Z-wear offset number you want to use for the tool * probe Z Offset set with Z_PROBE_OFFSET_FROM_EXTRUDER, M851, or the LCD. I too have a cr10 but I upgraded the firmware to a new version of Marlin than what was on there. It would also be useful if the Probe screens had X, Y and Z axis DROs particularly with the option to display distance to go. Here's how I got mine properly setup: Do an auto home. It will not work with other materials. Due to the design of the printer, the X and Y end-stops and the Z-probe are not exactly aligned with the It will probe 3×3 points and save the mesh to your printer. " Click "Measure Offset Z" again to release it and restore normal mode. 9. We export our cutting program relative to a local origin, and then tell the machine where that point exists. If it does you have to measure from a different point. Call your Roughing tool up (cancel all the bullshit) Call T0909 use MDI so there is a register on the screen of something, touch the tool off on the face (or skim the face) go to WORK offset, set Z zero in WORK, do not move the tool, go to GEOMETRY (be sure you are not using wear) clear the offset to 0, then calculate the TOOL geometry Z zero. When i select the Auto tool zero button the Z axis starts to lower it’s self and stops when it make contact with the tool sensor. We will probe at -35mm and a very slow feedrate of 20mm per minute. youtube. Now that the firmware is flashed, and the sensor is installed we can set the probe offset. When not in use, you can even wrap the wire around the X axis stepper motor a few times to make it is not in the way when actively working on projects. I've had to resort to repeatedly modify->compile->upload to fine tune my offset. I tried looking at the release firmware from Raise3D, i changed the values for the BL Touch there, but the firmware wont compile correctly. material One I/O for Zmin(White wire : endstop / Z-probe) GND and +5V power Most Board provides its own servo pin, so BLTouch can be used connected to one of those servo pins. 4, Marlin 1. Sadly this did not work for me. Mach3 work, click spindle F5,move slider for speed adjustment. and so on. One I/O for Zmin(White wire : endstop / Z-probe) GND and +5V power Most Board provides its own servo pin, so BLTouch can be used connected to one of those servo pins. Same things should happen when i swap from A to Z (Zero A gets saved onto A axis). Suppose the touch-off point is located at “Z0. If the z-axis bump stop is not on the head, the printer does not support automatic leveling. enter the command "M212 Z-1" to lower your Z axis offset to -1mm. It’s a good idea to verify that the Z offset is close to 1mm. M851 [ Z ] Parameters. 2mm), I dont want to re-level the bed and would rather add 0. * * In the following example the X and Y offsets are both positive: positive values will NOT work (move your Windows 10, Ruida controller Boss 1420. Enter the command G31 P999 X-40 Y28. com/watch?v=Zrib0LYrqlc&index=10&list=PLjT9TxDF2TDNjuN-UgHnaKL0GC29pUmXbAn essential step towards your d) Raise the hotend 10mm (or more) for probe clearance, lower the Z probe (Z-Endstop) with M401 and place it just on that mark by moving X, Y and Z; e) Lower the Z in 0. Anyway, there are several kinds of add-ons for printers (or included in my case) for adding automatic Went through the forums and tried cleaning the powder coated sheet with dish soap and warm water - that combined with lowering the z-offset even more gives better results. Either when the probe is triggered, the hotend is exactly at bed level; Or, when the probe is triggered, the hotend is above the bed by a given distance, which we will call the z probe offset. Once home'd, you may find a gap between where the bit is and the corner of your work surface. Note the feed rate and acceleration on axes. You can then turn the knob counterclockwise to move the nozzle closer to the bed in real-time or clockwise to move it further away. It can be used to compensate for a poorly-calibrated probe or other errors. 4. Disable Z axis = true in the Marlin firmware configuration if you want to operate a Z axis handle during 3d printing Disable Axis – line 228 // Disables axis when it’s not being used. I tried to change some things to the post processor without result. From here, install should match the Prusa MK2S instructions. To use the OSE 3D Printer with 8” bed out of the box-download the Lulzbot Cura configuration file for a 0. Hi, thanks for the comment. [Q<index>] Test Pattern. Now, we need to z-probe the actual z-height of the board and then reset the coordinate system for Z. 7V-Ender-3 Pro-32bit Mainboard-Marlin2. But washers will do the trick. Maybe it skips the touchoff and just starts executing. With G0 and G1 moves if there is also an incorrect work offset or probe length active, then there is a high probability of crashing and damaging or destroying the probe. Z offset does not work. I've set -0. Probably not very conventional what I did, but it worked for me. Now the printer in theory should go to 0. The probe is designed to be used in office-type indoor environments. This number will always be a negative value—the closer your Z-offset is to zero, the further away from the print surface the hot end nozzle will be moved. This number will always be a negative value—the closer your Z-offset is to zero, the further away from the print surface the hot end nozzle will be moved. You set 3 different heights in your cut profile. (Soldering and firmware update might be needed in rare case) autocalibrate/probe, parameter_set=sphere_cal3, qualtool_moved=no, show_summary=yes, overwrite_resultsfile=no begin autocalibrate results for probe point3 optiv using set sphere_cal3 probe file=point3 optiv date=9/26/2016 time=11:06:16 am tip1 theo x -55. 00 and the Z-Probe measuring 0. 09" and saved this value with "M500". What if you are not getting an accurate Z Offset from the Adjust the Z axis end stop trigger by rotating the screw counter-clockwise to raise the tip of the screw. 15 etc. Slicer: Simplify3D 4. Move Z down slowly until the probe triggers. Home the printer, G28. 3. You need to set Z-probe offset. If you get stuck in a DEPLOY/STOW loop, it usually means that the delta height or probe z offset is wrong, and the control board is not recognizing the probing switch. Once the correct offset are found you should input them into your firmware. Make sure to tighten the locknut to the adjusted position. 11 Sorry if this has been ask and answered before, but the Focus test software seemed to be changing a lot and I am not sure which threads are still accurate. 50. The LED on the sensor should be lit. First, for 0. F10. 5 If the effector tilt varies with XY position, then the relative heights of the nozzle and the Z probe will vary too, giving rise to probe height inaccuracy. . You just need a small amount and then move the z up and down completely a few times to spread the lube evenly. Now you have the runout, the probe tip radius and you can work out the Z offset of the probe tip pretty easily. (Soldering and firmware update might be needed in rare case) My settings for 3018 DIY CNC machine with Woodpecker’s control board and GRBL 0. 29! Then, set the Z-Probe offset from nozzle. Note the value of the Z-offset! Go back to the main screen on the Ender 3 Pro. In MMax, MLString "ZM +Z" command would move to the probe to the machine limits in +Z where ever the probe was located at. Go into your printer. Y0. ( 5. Mesur" but this time for the Tool's Z offset value. Thread PINDA wire from bottom up through mount and exit slot right behind fan along with fan wire. The x-axis and the y-axis move the right direction also homing direction is ok, but the endstop does not stop the bed or the x-carriage. 0 at the Z homing position. 15 from my 0. Using the Z-axis Offset parameter seems to allow for that fine-tuning of squash. In my case the Z-Probe is 50mm behind the hotend. I am using the cycle O9818 as well but the output given by the probe is the angle correction, the Z difference and the axis position. Burned an SDcard with the previous image I had just backed up but I had the same problem not being able to set the Z-offset. 10. Place a credit card on one the bed, the thickness of the card will be used as a reference distance. 4. Should work either way, I suppose, but I have not actually tried that. Click "Offset - Current Z" - this will set offset Z 5. ini" file, and search for "TMC3in1=1". Also, since the probe goes below the nozzle, the offset needs to be negative. These don't work on the woodpecker, as it uses commands from GRBL 1. Specifically, the Probe Z Offset menu item shows the value to the 1/1000 mm (0. Usage M600 [ X | Y | Z | E | L | AUTO ] X G29 P6 does not work seem to work. The “Leveling_sw” button adjusts the offset needed to use the leveling switch. No matter what the z offset says, it’s always the same. Setting the correct Z offset. If you have a machine that the gantry always gets out of level this may not work as well as probing a new mesh at the start of every print. As each servo pin has its own number, BLTouch will be controled with the servo pin number as following. Tabs / Bridges LightBurn will now let you Harness the power of your 3D printer and move up to better quality prints with Simplify3D Software. 1 mm. G30. . * * Example: `M851 Z-5` with a CLEARANCE of 4 => 9mm from bed to nozzle. You will want to add that number to the number you wrote down after the auto-home. You might also use the connector of your Z probe if you do not need a 5V power supply as the middle pin is missing. Now, you're going to move the Z-axis down by small increments until the nozzle just grips a piece of paper you place underneath. Download Lulzbot Cura. It then raises 10 mm and stops. Haas Tool Offsets and Work Offsets Filtering Option. If I remove the adapter board and replace the original z connecter the printer works properly. The Z offset can be a bit tricky, as the probe of the BLTouch extends below the nozzle when activated, so you’ll need to find the distance between the probe and the tip of the nozzle when the probe is fully extended. Make sure the probe stays perpendicular. 2 Z-35 F20 G92 Z0. It seems that adjusting Z offset with command e. Now, we can actually do the autoleveling using cnc-gcode-controller: * Z Probe to nozzle (X,Y) offset, relative to (0, 0). Press the “WEAR” soft key 5. * Only integer values >= 1 are valid here. Raise Z and deploy the probe. The Z-offset (set by M851 Z-x. Enter the command M564 S1 in order to re-enable your axes limits. Likewise, manually setting the probe attenuation is prone to user error. These axes tend to drift down if brake does not stop axis quick enough before power down. 3mm. I dont understand where the problem lays. If the M600 is triggered under 25mm it will do a Z-lift of 25mm to prevent a filament blob. (The offset is the distance between the nozzle and the bed when the switch is pressed. After a reset I executed "G28 Z" followed by a "G0 Z". 1mm steps, with the probe always touching the mark (it may be necessary to adjust X and Y as well) until you hear the "click" meaning the mechanical endstop was trigged. 5000 y 0. The nozzle moved down and the gap between the nozze and the sheet of paper was larger than before. face of your part and hit "Z Offs. firm files I dont know how to change the settings for the probe offset. the paper can still be moved at Z=000. Press the “OFFSET” soft key at the bottom of the screen 4. If the z-origin doesn’t get carved it’s easy. Deploy your Z-probe! The red LED on the sensor will only light up when it detects a metal. Click "Offset - Current Z" - this will set offset Z 5. Also, ensure you are probing COLD -- failure to do so can destroy some probes, including the ones linked to at the start of this guide. When i select the GOTO switch the Z axis only lowers 10 mm and doesn't take into account the sensor thickness. home the z-axis), you will specify the nozzle height above the bed in the appropriate, seperate G-Code command. To verify your current settings during calibration just an M666 will show the current offsets. // IF YOU HAVE A CUSTOM PROBE MOUNT OR ONE THAT IS NOT PRE-SUPPORTED UNCOMMENT THE // CUSTOM_PROBE OPTION IN YOUR PRINTER SECTION AND ENTER YOUR PROBE LOCATION BELOW // ===== # if ENABLED(CUSTOM_PROBE) /* * * Z Probe to nozzle (X,Y) offset, relative to (0, 0). 5mm On a vision system always measure the ring first with vision and always say YES its moved. Setting the correct Z offset. M600 - Initiate Filament change procedure M600: Filament change pause. 2. 2; Re-enable the soft movement limits using M211 S1 I am having the same problem. TIP: The auto-leveling probe is inductive and usually detects the bed a few mm before actually touching it. Now you have all the calibration numbers you need to probe. After successful pprobing, we reset Z to 0. Yeah. 0966 z 84. After installing the BLTouch, I manually leveled the bed using a piece of paper. I tried all your suggestions, but the probe won’t respond except for the initial self-test. Prusa i3, Z inductive probe. Move the bed away from the nozzle G1 Z20. Note: this method works best with setting the first layer height as 0. 2 DLL from the system path. If the paper won't go in at all, decrease the Z_PROBE_OFFSET, reload the firmware, do a "Load failsafe", "Store memory" and try again. I think a properly level bed and Z0 must still be performed before using this, but it could be used used for entire setup of squash as long as all the S3D profiles Finally, the Z value of the probe offset should always be zero! The leveling algorithm will only measure the deviation in height and not absolute values. Given that the source for the "4. Your vision probe should always have a TIP location of 0,0,#. I am assuming that I have to use the angle correction to compensate the initial G68. G28. So for a cutting a plate, your screen looks like The code looks like this, but i must check that : G91 G38. The UV scale & offset used for a lightmap. If not, then you probably want to move the probe up or down to fix this. The absolute (non-negative) of this value is your Z-probe offset. if so you must use gcode or lcd to change z offset. Click "Measure Offset Z" again to release it and restore normal mode. For the X and Y values, measure from the point of the nozzle to the center of the sensor. LB Version 9. * X and Y offsets must be whole numbers. Failure to do so will cause your nozzle to crash into the bed, and hardware damage can occur. The command G92 Z19. This means that sometimes a group of probes might be needed along a uniform wall if it is not axis-aligned. Press the Home Z button to home the Z axis. This will report the distance travelled by the probe. Z Probe Offset Control. Go to Prove Z-offset. (A straight Z move to the machine limits with No X or Y moves. If I’m right the probe is connected to te Z_MIN_ENDSTOP_PIN (I pulled out the z min endstop en replaced it with the bltouch connector with the black and white wires, so shouldn’t it respond to the Z_MIN_PROBE_USES_Z 2) control > bed leveling>probe z offset and set it to 0. This usually occurs on a Z-axis of vertical machining center or X-axis of turning centers. There was a point in time that during the first 4 points it searches for in the calibration process, it would pass the first one but not the second. I have the following settings in my config: #define X_PROBE_OFFSET_FROM_EXTRUDER 25 #define I have discovered that the Z-probe offset algotihm is not working for newer Marlin FW. Had prints starting too high, so adjusted print bed raising it some. This will also occur if axes are moving and the main breaker is cut off when they are in motion. (the offset number you use will depend on what M212 is currently set to and how much you need it to move) 1. Hi everyone, I am running into an issue with the replaced sensor, NPN NO LJ12A3-4-Z/BX-5V, and it will not pass XYZ calibration. Version 5. z In air temperatures exceeding the specified operating (XY&Z are all Zero) And BTW this a dedicated offline programming seat, not the computer where the probe was created. Then ask the probe to go find the bed. To test if the changes were successful, start a new print on your 3D printer and watch to make sure that the automatic bed leveling process executes at the start of the print. From the code it looks like you cannot change z probe offset x and y with M666. 2. You can also raise your offset with a positive number "M212 Z0. 57 – Exact Stop Canned X-Z; 58 – Cutter Compensation; 59 – Probe Offset X+; 60 – Probe Offset X-61 – Probe Offset Z+; 62 – Probe Offset Z-63 – Tool Probe Width; 64 – T. void retract_z_probe() { feedrate = homing_feedrate[X_AXIS]; destination[Z_AXIS] = current_position[Z_AXIS] + 27; prepare_move_raw(); destination[X_AXIS] = 65; // move to "retract shim" destination[Y_AXIS] = -58; destination[Z_AXIS] = 27; prepare_move_raw(); // push up z probe feedrate = homing_feedrate[Z_AXIS]/10; Connecting your Z-Probe Switch Using one of the homing limit switch ports, connect the z probing limit switch in series with the existing limit switch. " Click "Measure Offset Z" again to release it and restore normal mode. Positive would reduce squash by raising head, and Negative would increase squash by lowering head. If CurrentOffset = 1 Then ZOffset=GetVar(5223) ElseIf CurrentOffset = 2 Then ZOffset=GetVar(5243) ElseIf CurrentOffset = 3 Then ZOffset=GetVar(5263) ElseIf CurrentOffset = 4 Then ZOffset=GetVar(5283) ElseIf CurrentOffset = 5 Then The Probe is too low. Since both limit switches should be in the normally closed setup, the loop will open if either switch is triggered. The position of the pins on the board is described in the picture: I configured Marlin 1. G28 (Home XYZ) (Move Z at least 30mm away from the bed if it's not, and attach probe if you have a removable probe) G32 ( Probe the grid ) (Remove probe if you have a removable probe) M500 (to save probe results) G28 (Home XYZ) (jog down to touch the plate) M306 Z0 M500 (to save homing offset) G28 (Machine is now grid-levelled and knows it's $\begingroup$ I came here to solve an issue during an MMU2S tool change from PLA to TPU where TPU like some other flex materials needs a slightly higher Z offset. Then it worked. The change in mounting means the calibration wizards will fail, only calibrate the Z height. Tiny Machines 3D is a Houston, TX based company aiming to provide great working 3D printers, upgrades and filament to new and old printing enthusiasts. This number is completely arbitrary. So I tried to add more Z offset, about 0. To do this just repeat the steps below in the “Steps to generate and store the bed leveling mesh” section. xx is needed to set the offset between the nozzle and the sensor trigger point (to the bed). 0, your mileage may vary), so that the Z=0 position corresponds to the nozzle tip. The probe should trigger and the Z movement should stop. We tested a lot internally, but a number of users on low resolution systems, and some Macs, had issues with it, including some network drops and performance issues, so we've rolled it back to the one we had before. I am however having significant trouble calibrating my whole printer, and am getting prints that dont stick and very inconsistent results, such as the hot end being much too close to the bed along its left hand side, even after the insane detail probe. 20150930. In this case, the printer has set the current position (home position) to be Z = 0. Start printing, checking your first layer adhesion and the correcting your M212 until you are happy. 1 If your M212 value is set at Z0 and the layers still appear smashed, try using the wood wrenches to adjust the leveling probe closer to the bed. If the 4. com NEW AND BETTER VIDEOS ON Z OFFSET: https://www. In fact, once it's in EEPROM, how do you change it at all? Seems like the only way is to put it in the compiled code, define Y_PROBE_OFFSET_FROM_EXTRUDER 58 // Y offset: -front +behind [the nozzle] define Z_PROBE_OFFSET_FROM_EXTRUDER 0 // Z offset: -below +above [the nozzle] This is the default from Skynet 2. Now that the firmware is flashed, and the sensor is installed we can set the probe offset. As you see i added the 50mm's at the back of the bed. 0000 z 84. This is what I do for my thc. Suddenly I got an offset of -1. But sometimes it also says: x_min: TRIGGERED y_min: TRIGGERED z_min: open z_probe: open. 4mm, then note an average Z offset of 000. I hope someone can help. Soft limits typically are placed just inside the working area in a way that the home or limit switches will not be activated. This may be required when the z probe needs some force to trigger and this bends the bed down. 25 first layer with PETG. Now, I would like to be able to change my Nozzle To Probe Offset after changing the BLTouch mount that I am using. 10 will set the “0” position for the Z Axis 19. Removable probe MUST be attached for this to work. 0 (or maybe -3. It will then retract and calculate the Z zero taking into account the height of the sensor. 1RC2; mini-sensor board by dc42 for auto-leveling Ormerod common modifications: Mini-sensor board by dc42, aluminum X-arm, 0. Jog the X and Z axes so that the tip of a turning-stick tool [2] is near the probe stylus [1]. Keith If this is not working then you have an issue with how you are entering the data into the tool table. Alternatively, you can set Z to zero for now and fill it in later, or leave it at zero and save the value to your controller’s memory after setting the Z offset. Load the specified Test Pattern to check for correct operation. Inspect the foot pedal to see if it’s working. 2, 208. 67. Check if you've got the eeprom enabled in configuration. for V-Series. Because you are using the tip of the master tool as your zero the offset of each subsequent tool will be the difference in height plus or minus. Octoprint plugin adding Z probe offset setting on Marlin based 3d printers An illustration of what an existing home offset looks like, which can be compromised after build platform re-levelling. stl as a sample print file. 2mmAlso, if you can't move your nozzle below 0 in the Move Z menu, send the following G I am trying to get my Probe working in Mach3, so I entered 2 tools into my tool table, tool 99 (my probe) at 6. That gives you a safe way to measure the Z offset. I had to tell it to use some “other” pin for the probe, and oh by the way the pin I want to use is zmin. g. G30 Fxxx will run the probe at xxx mm/min overriding the slow_feedrate. An alarm will occur if the "Probe" input does not switch before the endpoint is reached. Check the Pin. M212 Z[Z offset] M500 ; to save. G92 Z0 sets the new position to be Z0. 55 If you do not know the offset value, you should leave this offset at 0 for now. 1) increments. I then set G59 offset to all 0's in the control, which then mirrors the MCS system. If it is nonexistent or not high enough, try setting the power higher. Flashed EEPROM clear. Put in the value you recorded earlier (ex. If you are also using the probe to measure the absolute height above the bed (i. assign the Z probe to Z-min (this is the proximity sensor) #define NOZZLE_TO_PROBE_OFFSET { -27, 5, 0 } Typical probe cycles for machining centres Typical probe cycles for machining centres Simple to use canned cycles for basic features Inspection probe Inspection calibration Bore and boss measure Probe XY offset calibration Web and pocket measure Stylus ball radius calibration Internal and external corner find Probe length calibration Im sure the firmware from here will not work for my setup and since I cant edit the . 1 and then M500 only makes probe readings change - I can see different probe values when changing Z probe offset, but height still stays the same - currently too low. Then, I used the menu options on the printer to set the Z offset. The vision probe is the Master that everything else is offset back to. The result is that any movement command after this will be lowered by 0. In layman terms, Z-probe offset is defined as the Z height of the probe with reference to the bed and nozzle. #define BLTOUCH #define NOZZLE_TO_PROBE_OFFSET { -23, 0, -2. Initiates Filament change, it is also used during Filament Runout Sensor process. 71 } #define INVERT_X_DIR false #define INVERT_Y_DIR false #define INVERT_Z_DIR false #define INVERT_E0_DIR false #define INVERT_E1_DIR true //#define MIN_SOFTWARE_ENDSTOP_Z. But I have no idea how to change this behavior or if there is another way to solve this without changing my inductive sensor position every time (which is exhausting, and innacurate, at best). I want to probe a z surface and everything seems to be ok till the line "cycle 978 " ,i get a red light and alarm with the message : Block 937 :Probe not calibrated in active plane or wrong calibration data record. 28-05-2013 #3 cropwell I am not sure what will happen if your code specifies tool #1 again. regardless of the setting, the bed never moves and remains about ½ inch below the extruder which makes it impossible to print because the bed never comes close enough to the extruder. The tip of the nozzle should now be very close to the surface of the bed. 1- BLTouch-TMC2225. These are other open DNS servers on the internet. It’s more about how these work together to provide a smooth operating system. This is a problem for me because my ideal offset seems to be right in the middle, and I'm left with either poor adhesion, or over-squished first layers. localToWorldMatrix: Matrix that transforms a point from local space into world space (Read Only). Then verify a positive movement is away from the end stops. If it is not grounded there can be electrical interference that can cause the sensor to not work a. after few tries, the bed is ~2 inches above the bottom of the Solidoodle. 04mm from the Z height offset (-. " The connections to the USB interface is as follows: - The spindle is connected to the gnd terminal (which is also connected to the end mill). It will not work with other materials. The probe tolerance in millimetres, anything less that this will be ignored, default is 0. 4). I went into the offset tab in Mach3, I changed the tool from 0 to 99 which is my probe, and I am using the following macro for Z: If they do not match then the kit will not work correctly. Note: the offset may be positive or negative. If e. just as if it gets accumulated over and over. As each servo pin has its own number, BLTouch will be controled with the servo pin number as following. ")); return;} if (isFirstCyclePoint()) {repositionToCycleClearance(cycle, x, y, z); // return to initial Z which is clearance plane and set absolute mode var F = cycle. Found it more useful than setting it live. Import, repair, slice, preview and print… all from one integrated desktop application. – Probe offset is not working properly for the 1169A. 4 // offset with 2. #define Z_SAFE Work probes for Wireless Intuitive Probe System (WIPS) do not work in the wired probe systems (VQCPS). #define MIN_SOFTWARE_ENDSTOPS Now chose your bed levling procedure. I don't want to update the firmware and screw up the PI. #define AUTO_BED_LEVELING_BILINEAR. Make sure the power cord your printer uses has a grounding plug. Look at the adjustment valve and check the hydraulic power. I am now working on a totaly new idea based… Continue reading New Z probe offset The red LED on the sensor will only light up when it detects a metal. You have to push the appropriate offset button before engaging the leveling Follow the directions in the Probe Calibrate guide to set the x_offset, y_offset, and z_offset config parameters. I do not know how you got any good prints with a z offset of 0, that shouldn't work out. The procedure will be to set the laser head so that the distance measurement is >= 45 mm and then hit the Z Focus button. M501 ; to check your save. The offset values work for me. Change it to "TMC3in1=0". The work probes can be differentiated by: The VQCPS work probe (P/N 60-0024) has a square Haas logo. You can use an input on your CNC Controller, but if you don&rsquo;t have free inputs because they are used for Limit Switches like in my case. 2. 10mm below it’s current position. 10 but it does not. The sequence to determine the offset is: M851 Z0; // Set the Z offset to zero height G28; // Home Z in the middle of the bed G1 Z0; // This will move the head to zero height; M211 S0; // This will disable the end stops so that you // will be able to proceed lower than Z=0 is you z-height correct? if its to high it would crash into the bed. You will need a “JST XPH-3” 3 pin connector. Because probes wear out, and because the auto-sensing circuitry is not compatible between different oscilloscope makes, auto-sensing probe scaling is not foolproof. 0. 1. So Haas has a useful function of filtering all those offsets which are not used by the program. Or use a caliper and measure bit length from collet and calculate. Optional D<delay in cm> to set delay in centimeters between sensor and extruder If you can update your firmware, this is a cheap way not to have to add a Z probe to your printer. This will create a -0. c – Fine Tuning the Z Offset. Most of the times it says: x_min: open y_min: open z_min: open z_probe: open. I believe this is because the inductive pinda works differently on that. Z-position on a work piece as accurately as possible. Now prints start too low, squishing filament into bed. In every Cheetah 5. Then tighten the probe. The LCD display should show Z = 0 From the display go to the Menu then Prepare/Move axis/0. If this is the X-axis, you can loosen the mounts below the work surface and slide the work surface to the left or right. Well. 1). 1 from this value to account for the thickness of the paper. Home the Z axis again. 12 to 14 we updated to a newer version of the framework LightBurn is built on top of. 1, 4. dwell * 1000, 99999); // in milliseconds And then, see what values you get back. 04) = -1. 4 mm nozzle E3D like, 2nd fan, Z stepper nut M5 x 15, Herringbone gears, Z-axis bearing at top, spring loaded extruder with pneumatic fitting, Y belt axis tensioner Description. 20. So I executed "M851 Z-1. But at one point simulation used to work, i just cant remember exactly the last time it worked correctly but ill guess 4 months ago, and nothing major that i'm aware of has changed in that time. The nozzle should touch the bed. Try to be as accurate as possible. I tried looking at the release firmware from Raise3D, i changed the values for the BL Touch there, but the firmware wont compile correctly. If some old Z offsets are still in EEPROM and you start to configure printer you could potentially have the nozzle hit the bed because of old Z offsets were not erased. There is nothing better to calibrate the z-probe offset than to tune it with a live print. If you are having issues with the EZABL not triggering when connected to the Z-Stop header you can use the servo header pins. If the tool does not align with the center of the stylus, turn the top 3/8-24" x 2" setscrew [3] to move the stylus up or down. I thought i'd try fusion 360 instead and have been having an issue where my part is either way off in space or the offset heights (feed, travel, clearance, stock, etc) are either below or above where i zero xyz on the stock material. However, they are likely to disagree on where Z=0 is. 0000 d 0. Some people use an endstop and Z-max and also a Z probe. 200. To raise the nozzle to print on a surface, you’ll want to use negative values of Z offset (Z-0. 2. . The Z axis will lower slowly until it contacts the sensor. Step 1 Prusa i3 MK3 Firmware Modifications Because the Prusa i3 MK3 already uses an E3D HotEnd the firmware change for Hemera consists of changing the E steps per mm and entering new nozzle to probe offset values. It’s useful to be able to adjust the height of a mesh. If the spindle is not started, please make sure that; connection is right; And VFD belong to analog voltage control Make a note of the Z offset. My goal in the end is that I want my mesh to be higher, so that all I need to do is issue a M420 S1 to instate the mesh after a home command and walk away. 3. Turn the Z axis with your hand until the nozzle hits the credit card. com. A crash can also cause this to happen. This menu option is only visible while the printer is printing. In this example, I have it set up to home axes in the following order, Z(1), X(2), Y and its slave(3). I recommend you do this anyways as it will help ensure smooth operation of the printer. . 15m) to get -0. -2. This is used if your nozzle is not exactly at the same position as where your tool would be. So I disabled the endstops again and lowered the nozzle. This command can be used to enable one or more steppers (X,Y,Z,E). 2. It will be snug fit. 127 ILLEGAL DIR. Hope someone has an answer for this. $$ $0 = 10 (step pulse, usec) BLTouch sensor wire soldered to original Z-axis end stop wire Helping hands to the rescue stripped and ready to be soldered. That's the only reason that we allow a Z probe to be used as an endstop. That is why the Z probe XY offset from Hi, I have spent time levelling the bed on my 2+ with PLA and now want to print with PETG, but PETG requires a greater Z offset (an extra 0. Demo Request Form WinCalXE software is a comprehensive and intuitive on-wafer RF measurement calibration tool to achieve accurate and repeatable S-parameter measurement. This commonly happens to me when I forget to SAVE changes, and recycle the power to the printer. Instead, use a known height block, lower the tool so that the block would not slide under, and start raising it up slowly until the block just passes under. Press the OFFSET hard key on the operator’s panel. The instructions included with the printer that tell you to mount the proximity sensor 2mm higher than the extruder tip don't match the Z probe offset in the firmware. Im sure the firmware from here will not work for my setup and since I cant edit the . Move hot end to several positions of the bed, starting from the 4 corners. I did use the 2mm and found the z-offset at around -2. I would recommend using a different physical pin besides zmin, and I think it would have been much easier to configure. ) There’s another Z-offset button that sets it to the default offset for using the leveling pad. What's wrong is to configure a Z probe as if it is a Z endstop. 4 nozzle and Titan Aero Extruder at OSE The height measuring distance for the probe function is for example 100mm in z axis. 0) If your firmware is a marlin derivate and is not listed as tested, please report it as a working one in order to add it to the list, or report any issues. 5mm (Z nozzle offset) - 1. Adding even more Z offset does not work either, the printer prints the first layer at 0. 9 + (-0. Reply. Needs to go up Put a credit card under the probe and then lower the hotend until it just touches the bed. 1mm/Move Z Now move the Z axis slowly down until the nozzle is the right distance from the build plate (folded piece of paper or thin card). z probe offset not working
