Had one of my Nema 23 motors going bad on my Open Builds machine using the original Black Box controller. It was the X motor and wasn't always coming back to the start position. I found that I was able to turn the shaft while power was being applied to the motor. I order several Nema 23's from Amazon. What was delivered was a somewhat larger (in length) motor and was labeled a "57 Series" motor. The specs were equivalent to a Nema 23 as close as I could tell. When I connected the new motor it did not work as expected. Wiring was correct and the 2nd motor exhibited the same operation. I did swap out one of the other Nema 23's and the Black Box ran it fine. Any ideas?
Very unlikely to be the motor, more likely: docs:blackbox-x32:faq-identify-motor-coils [OpenBuilds Documentation] one of the 4 wires not making contact throughout Still sounds like wiring
