Again. I'm 99% certain that the problem is not lub related. If it were I would see or hear the steps attempt to move. I do not. A lub problem is not a sudden failure in most cases. It had been only a few days since the steps were working perfectly with no rubbing or grinding associated with a lack of lubricant.
When I get time I will roll up onto blocks so I can check all the nasty looking wires and connectors. If this inspection doesn't expose a problem I will see if the motor is getting power when it is supposed to. Once the motor is disconnected I can test the armature and field circuits.
I thought the same thing too, there was no noise. But the controller has an over-current protect so it will not supply unlimited current to the motor if the steps are jammed. My experience was exactly the same, the steps worked perfectly, then they didn’t.
