Machine: K40, came with M2nano, previously replaced with OMTech K40+ before switching to C3D (for Z-table needs).
Board: Cohesion3D LaserBoard
Problem/ Question: The board seems to have trouble homing. With the OMT board, I hit Home, and it would go to the end stops, bounce off them twice, then retract 5mms as expected.
With the new C3D board, the laser head goes up to the X end stop and stays pressed against it. If I press Home again, it will back the head off and then press back against the end stop, never retracting after engaging the switch.
endstops_enable is set to true.
alpha_limit_enable, and beta_limit_enable are currently set to false. I tried setting them to true (same as the OMT K40+ board), but if I do that, the head hits the end stop and triggers a lock and freezes. In either case it doesn’t go to the alpha_homing_retract_mm / beta_homing_retract_mm position.
