Ender 3 V3 KE bed issues

New printer. Assembled and initially setup fine but then:

  1. Tried to print the Boat and during calibration the plate would go too far FORWARD and the head would try and descend off the rear of the plate. Threw a code and stopped. Tried several times and no change. NOTE THE plate calibration during setup ran fine.

  2. Moved the printer and tried calibrate again as usual…now the plate moves REARWARD and the belt starts slipping as it continues to try and move back, like the limit switch isnt working there.

Any suggestions other than repackaging and returning it?

Check for something blocking the limit switch, found an errant screw on my bed that caused a little issue. Dunno where the screw was from, I’m an engineer so could have come from anything I work on.
