I have an old Prusa Mk3 that I'm going to repurpose into an XZ motion system for a camera. Since I won't be doing any bed probing, I need to add a z-endstop switch. I have a switch and I see that the Einsey board doesn't have anything plugged into the x or y endstop pins since the printer uses sensorless homing for those axes. Does anyone know what firmware changes I'd need to do to take advantage of those free pins to add a z-endstop? Thanks.
