I spend some time trying to troubleshoot this issue w/ Z axis not homing to Z_Min endstop, but cant find the issue w/ my config. The Z axis moves in the right direction either to Homing or to moving direction +/- with controller, but the Z home command won’t lower the axis till it triggers Zmin_endstop. To illustrate a bit, once I fire Z home command, Z Axis moves down a little bit, then stops, bump up and go back to that first stop. Just as it does if it had hit the Z mechanical endstop. If I keep sending Z home command, it goes on down keeping the same patten. Cant anyone look at my config and give me a light on this. Thank you in advance.
Without and switches being pressed, send m119 to the machine and copy paste the results. Also (I’m on my phone so i can’t look at your config), what firmware are you using and did you modify it?
It’s a week ago old version Marlin 2.0. I did modify it to my board MKS Gen_L 2.1. I did test M119 prior to this post and everything is triggered when home except Z that is always open. Before I had in config. (Z_MIN_ENDSTOP_INVERTING false , ) and Z was always triggered. Thank you for replying.
