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. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. Instructions are in the comments. So search and enable Z_SAFE_HOMING. Trish Trish. It seems to be driving ok apart from the steps per unit seem to be out. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Z Safe homing; Advanced pause and filament change; It’s assumed that you have the following equipment: BTT SKR 1.4 Board. dual z marlin 2.0 SKR tronxy x5s. When I do a G28 to test the print head goes as expected to the front left of the print bed. Use M206 to apply a persistent offset to the native home position and coordinate space. If compare to the latest (v1.1.9) Configuration.h file from GitHub, here are the changes: This effectively shifts the coordinate space in the negative direction. 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. //# define MIN_SOFTWARE_ENDSTOP_Z… It’s safer to leave Z as 0 here are calibrate this yourself later. Instructions are in the comments. 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. #define Z_SAFE_HOMING. Z_SAFE_HOMING. I can not get this thing to home the z-axis properly, much less complete G29 for autobed leveling. In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. #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.) Every time a setting is changed on a 3D printer the information can be lost if it is not saved. 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. * * If using a Probe for Z Homing, enable Z_SAFE_HOMING also!
