I picked up a used Ender 3 V3 KE, and it’s having issues. When I try to print, as soon as it starts to move, it re-boots. In the setup menu I can move all axis, I can heat the nozzle, I can extrude, I can retract. I even leveled the bed, and set the Z-axis offset.
But as soon as I try to print, it shuts off, and reboots.
