My Mini 2 (non ES) is having issues moving the bed around. During initialization the bed will move up/down, left/right, and forward/backward without issues. While calibrating up/down works every time but only sometimes will it function in all directions; about 70% of the time it will not align to the little tab to complete the circuit on the screw head. While printing the deck will move up to the nozzle and begin to print but will only move left/right so it just keeps printing over the same location varying the distance it moves for the ‘layers’ that it is trying to print, but does not move the bed down nor forward/backward. I was thinking of trying to re-flash the firmware on the unit to hopefully fix any odd glitch stuck in there, however I cannot find a firmware download for this unit. Anyone have an idea what else to try?
