OK, so I have the machine plugged in again, back on the original circuit. The motors are locked up and holding position. Nothing is connected to a computer. So far, no weird noises. I need to run a few more errands this afternoon so I’ll hook the computer up later and see if that introduces the clunking.
While I’m here, do I need to be concerned about the driver getting hot? After a while the enclosure I have the electronics in gets warm to the touch, which means the driver is getting pretty toasty. Is it rated for that kind of heat or should I be looking at a solution to this?
