Hello, I have a stepper motor that seems to not run occasionally. Other times it works fine. Of course this motor is on a twin X axis, meaning that the x-axis has two stepper motors each with the same signal. When one fails, this moves only 1/2 of the machine, which is very very bad! Basically worst possible one to go out.
Is this a normal symptom that you guys have seen? I'm wondering if I need to order a new motor, or I need to investigate something else. When they go out, do they act flakey and then finally give up the ghost, or do they just go out immediately!
This is a NEMA 34, 1290 oz motor. It's moving a gantry that weighs probably 250 lbs.
