Description. #define X_BED_SIZE 220 #define Y_BED_SIZE 220 // Travel limits (mm) after homing, corresponding to endstop positions. 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. So search and enable 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 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. Every time a setting is changed on a 3D printer the information can be lost if it is not saved. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. * To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below. README.md: 2020-07-27: 12.6 kB: 0. Please Help going nuts! It seems to be driving ok apart from the steps per unit seem to be out. 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. Undoubtedly without the EEPROM option being enabled, many of the Marlin … Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . 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. It’s assumed that you have the following equipment: BTT SKR 1.4 Board. #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.) 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. So search and enable Z_SAFE_HOMING if using a BlTouch or probe.

This build is a suppose to be a dedicated, large format 3D printer. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. // - Prevent Z homing when the Z probe is outside bed area. BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring). 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 a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. @section extras. Removed Safe Homing ( printer no longer homes Z in the middle of the bed, I can't see this being beneficial if you are not using a probe.) #define Z_SAFE_HOMING. 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}). #define Z_SAFE_HOMING. define X_BED_SIZE 230. define Y_BED_SIZE 230 // Travel limits (mm) after homing, corresponding to endstop positions. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. I have the feeling the distance is multiplied by 2 for some reason. * (By default Marlin assumes the Z-Max endstop pin.) 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. Marlin [2.0.5.4 Z_Safe_Homing not centered, Bltouch going off bed. But it then goes to the center of the bed. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing. Instructions are in the comments.
