Hello guys,

I've been trying to diagnose a skipped steps problem, that I seem to be having part way through operations, after around 20 - 30 minutes of machining.
The X axis will randomly jam for 3-4 seconds, performing an identical cut that it just completed 70-80 times successfully, and then resume moving partway through the cut, now displaced be a few cm's.

I thought maybe it was caused by a lack of torque, and now I am wondering if it is the case, due to motor overheating causing a loss in torque?

Aside from reducing the peak current from the driver, what other things reduce heating?

Reduce acceleration? or speed?
