Here is what I have in Marlin 2.0 – I’ve tried everything, so please let me know what doesn’t look right. If you have a capacitive sensor, electro-mechanical, or just mechanical sensor for Z, you can search for that in "Configuration.h", uncomment to enable it and then upload the firmware to the board. @section extras . It’s assumed that you have the following equipment: BTT SKR 1.4 Board. * To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. Trish Trish. But it then goes to the center of the bed. #define Z_SAFE_HOMING • Uncomment line 110 - #define CUSTOM_PROBE • Go to line 401 and set X offset to mount offset (recommended mounts use -40 for the X offset.) In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. • Go to line 402 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) Marlin [2.0.5.4 Z_Safe_Homing not centered, Bltouch going off bed. It seems to be driving ok apart from the steps per unit seem to be out. Marlin 2.0.6.tar.gz: 2020-07-27: 4.5 MB: 0. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. Thanks for any help. @section extras. The current position is adjusted to align to the new home offset values. Marlin 2.0.5.3; Filament Runout (Connect to E0DET pins) Square Wave Stepping (Beta Feature) * Create a 50/50 square wave step pulse optimal for stepper drivers. Creality offers the firmware on their website as a .hex file - which is hard to edit. Please Help going nuts! Z_SAFE_HOMING. dual z marlin 2.0 SKR tronxy x5s. This is a no-brainer for every CNC owner which finds it logical for Endstop and E-Stop switches being de-facto limits which unconditionaly stop any CNC movement (unless disabled with M121). Use center XY for Z Safe Homing default; Independent X2,Y2,Z2,Z3,Z4 endstop inverting; Add a custom nozzle wipe G-code option; Board / HAL. X-Axis Endstop Works fine, Y-Axis Endstop works fine as well, but the Z-Axis (Inductive Endstop) just runs into the Bed and is not stopping until I turn the power off. Use M206 to apply a persistent offset to the native home position and coordinate space. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. This will let you adjust the Z to a negative number for your offset. Marlin 2.0.4.zip: 2020-02-21: 5.4 MB: 3. define X_BED_SIZE 230. define Y_BED_SIZE 230 // Travel limits (mm) after homing, corresponding to endstop positions. Features Highlight . Totals: 3 Items : 10.6 MB: 5: For this release we focused on compatibility with a wider range of boards and controllers, especially STM32-based boards, color screens, and touch screens. Ender 3 or 3 Pro; Preparation. It’s safer to leave Z as 0 here are calibrate this yourself later. Everything worked really great until I arrived at Autohoming. i.e. Importantly if you using a BlTouch or probe, search for and enable Z_SAFE_HOMING. G34 test points can now be auto-assigned; Z_AFTER_HOMING for a standard raise after G28; Individual edge insets for corner leveling; Separate config for secure data (Excluded by .gitignore) Boards / Pins. BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring). Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . //# define MIN_SOFTWARE_ENDSTOP_Z… I installed a BLTouch bed leveling probe on my printer which uses Marlin 2.0.5.3. Z_SAFE_HOMING. Z Safe homing; Advanced pause and filament change; It’s assumed that you have the following equipment: BTT SKR 1.4 Board. Ender 3 Pro or 3. See examples below. Today I flashed my Anet ET5 with the Marlin 2.0.X Bugfix Branch, following the Tutorial DrVax made (great Tutorial ,I am probably just stupid). Z_SAFE_HOMING. I can not get this thing to home the z-axis properly, much less complete G29 for autobed leveling. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. For 3 days I have been trying to get my MPCNC build working using Marlin + RAMPS 1.4 and now I am about ready to light this thing on fire and push it into the driveway. * - Use 5V for powered (usually inductive) sensors. #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28). I recently upgraded from an Arduino to an SKR 1.3 running Marlin 2.0 and have been trying to make the printer auto level. When the print head strikes the bed the Z-min endstops open signaling that the bed is touched. README.md: 2020-02-21: 2.9 kB: 0. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. It’s assumed that you have the following equipment: BTT SKR 1.4 Board. Now the printer seems to be of two minds when it comes to finding the origin. #define Z_SAFE_HOMING @section extras. Without this option enabled the nozzle will crash into the bed when homing. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Z Safe homing; Advanced pause and filament change; Classic Jerk or Junction Deviation (see note below) Read more on changes/fixes in the official Marlin 2.0.7.2 change log and Marlin 2.0.7.1 change log. Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. When I do a G28 to test the print head goes as expected to the front left of the print bed. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Without this option enabled the nozzle will crash into the bed when homing. Ender3 Pro Octopi Marlin [2.0.5.4] SKR1.4 turbo w/220 … * (By default Marlin assumes the Z-Max endstop pin.) README.md: 2020-07-27: 12.6 kB: 0. #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". For the whole day I am trying to configure Marlin bugfix-2.0.x to achieve seemingly very simple things: Always monitor endstop switches when moving. This build is a suppose to be a dedicated, large format 3D printer. * * - The simplest option is to use a free endstop connector. Not sure what I have screwed up. In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER.

So search and enable Z_SAFE_HOMING if using a BlTouch or probe. Please Login to Comment Gnattycole . I want the print head to end up at the front left and that spot being 0,0,0. The idea of Z safe homing is that it is forced to home Z in the middle of the bed (bed size/2) so the inductive probe does not try to trigger in thin air. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. So search and enable Z_SAFE_HOMING. I have the feeling the distance is multiplied by 2 for some reason. Not sure if anyone has successfully cracked this but I'm trying to set up a dual Z drive using the E1 port as a Z2 stepper driver. Without this option enabled the nozzle will crash into the bed when homing. * Enable this option for a probe connected to any pin except Z-Min. I left Z_SAFE_HOMING enabled and instead of going at the middle of the bed, it goes at the top end right corner ({30,30} instead of {15,15}). Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. And your Z-Safe homing config look like this. Description. Last Bed Leveling results Recv: echo: G29 W I0 J0 Z-0.09000 … Dec 11, 2019 .

It’s safer to leave Z as 0 here are calibrate this yourself later. I have a Robo R1+ which uses the nozzle contacting the glass print bed to level the printer. Every time a setting is changed on a 3D printer the information can be lost if it is not saved. #define Z_SAFE_HOMING. According to Repetier Host it runs on Marlin 1.0. If compare to the latest (v1.1.9) Configuration.h file from GitHub, here are the changes: x and y vibrate when moving to the z safe homing point by macalikm: 112 2: 12/02/2020 04:02PM Last Post by macalikm: endstops always on per endstop? BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring).

In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. After the final adjusted firmware upload, and bringing the sensor up, I see that the extruder pushes the bed down a bit when I auto home and then the LCD screen says probing failed.
