I own a Comgrow Creality Ender 3 3D Printer Aluminum DIY with Resume Print 220x220x250mm
I am a newbie and last night finally got a halfway decent print, but tonight I went to Auto Home it and it just keeps trying to move down, down down even though it physically can't go any lower. The z-axis just keeps trying to spin down. The long threaded metal rod just keeps turning like it needs to keep moving down. Any ideas?
