I dont have a PC.... just the mac.
We were trying to do the buildplate leveling/calibration when it goes to that corner and doesnt stop.
This is a new development as the first time we calibrated it homed correctly (front left). Then we had to adjust the Z stop because we were having extruder issues (prints were coming out stringy). After we adjusted the nozzle we tried to recalibrate and the nozzle homing onto the build plate clips - and then did the thing where it seemed to home in the back right corner and ignore the limit.
