"endstops hit: Z" stops any axis movements, how to reset?
When I home all axis, lcd screen posts "endstops hit: Z", and control of all movement stops. I've tried disconnecting computer USB and restarting Printer and reconnecting USB but nothing changes. I turn Z axis threaded rods to move X axis assy up to above Z endstop and then regain control of directions for all axis but lcd still displays "endstop" error. What have I done wrong and how to fix.
