BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring). When the print head strikes the bed the Z-min endstops open signaling that the bed is touched. 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. Trish Trish. Undoubtedly without the EEPROM option being enabled, many of the Marlin options will be lost once … Thanks for any help. 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. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). 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). Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. I want the print head to end up at the front left and that spot being 0,0,0. 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. 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. //# define MIN_SOFTWARE_ENDSTOP_Z… This feature is so sensitive that it can actually take the place of traditional endstops. Z_SAFE_HOMING.

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.) I have a Robo R1+ which uses the nozzle contacting the glass print bed to level the printer. It’s safer to leave Z as 0 here are calibrate this yourself later. 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. 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. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. // - Prevent Z homing when the Z probe is outside bed area. But it then goes to the center of the bed. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Now the printer seems to be of two minds when it comes to finding the origin. Last Bed Leveling results Recv: echo: G29 W I0 J0 Z-0.09000 … 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}). Instructions are in the comments. Bed size: 235 x 235 Nozzle is at front left corner of bed at (5,5) // The size of the print bed.
