🥉 Marlin Z Axis Not Homing

The endstops do not restrict motion when not homing. Given all of that. My guess is that one endstop on your Y is not connecting. You can check with M119. You can also try swapping Ymin and Ymax to confirm. If you do, the other motor will start homing, but you'll still have a broken wire somewhere. 1 Like. Sorry if this solution has been posted before, I couldn't find it. I just recently got an Ender 5 Pro for Christmas as many others have, set up went okay. No BLTouch but the 4.x silent board. When I select auto home, the z axis drops a little, the x and y go to the back right corner as they should, but then the z just just drops a little more Z axis homing with bltouch sensor is not working properly. Replaced a dead SKR minie3 V1.3 board with a new V.2 board. the BLtouch does it's little dance test, and I can trigger testing through the touch panel. I can 'drive' all axis through the touch panel properly. When I tell the printer to home, the X and Y axis home properly, but the Z 1. Y axis operated in an inverted manner. 2. Y Homing went towards -Y, instead of +Y. Changing INVERT_Y_DIR from false to true did fix the inversion issue. Changing Y_HOME_DIR from -1 to +1 did not fix the homing issue. When set on -1, it would, if allowed, move to the maximum -Y value without stopping. Seems the home position is not correct with X-axis, despite the fact that I did set the printer dimensions in the file. Bed dimensions have no influence on homing since homing put the printer to XYZ 000. And zero is always on the endstop. Z-axis endstop not functioning after Marlin Firmware installation. 3. Anet A8 with Marlin firmware The correct way is Z wire going to V "soldering point" and the other wire going to S "soldering point". I've managed to loosen the wires from the terminal and place them in a correct way using a flat screwdriver that came with the other Ender 3 tools. After switching wires to correct position the z axis started to autohome correctly and z stop This Issue Queue is for Marlin bug reports and development-related issues, and we prefer not to handle user-support questions here. (As noted on this page.) For best results getting help with configuration and troubleshooting, please use the following resources: Marlin Documentation hosted on MarlinFW.org; Marlin Forum hosted on RepRap.org Using the M203 command to set a new Z max speed value and finally saving it with M500 to the EEEPROM. You probably realize that by changing this max feed rate value in the EEPROM we can actually change the fast probing speed for the z-axis to any value equal or below what we have set to Z_PROBE_FEEDRATE_FAST. So you have 3 options. Re edit Marlin configuration.h and recompile etc. If you connect with pronterface or Octoprint and use a terminal window to send the command to temporarily disable soft end stops. EDIT (M211 S0 ) Set the Z off set to something larger than the actual offset . Example 3mm. 5Pqv.
