My operator powered our lathe off with the tailstock still coupled with the turret. After power on, we get no function out of the lathe. It will not jog, handle, rapid, or move anything period. The tailstock buttons are no longer lit up and don't function. Does anybody know how to fix this? Is there a recover? Does anybody have a fix? I could use a brief explanation.
