Hello,
My printer has ~2000 hours on it and has been working great up until now. I had a print fail due to a Z-axis error. When i tried homing after discarding the print, the bed went straight up into the nozzle and kept driving once it made contact. I reset the machine, repositioned the build plate, and the bed continues to crash into the nozzle and keep driving. I have already replaced the Eddy Sensor, which did not change anything. What else could this be?
