In the middle of a very long program the left motor stopped working. Here’s where it went wrong:
With the sled on, it jerks the sled like it’s trying to move and gears are slipping. Without the sled, it moves, but makes grinding noises.
I ran the motor test, and all motors passed:
I’m hoping I can still salvage this piece by flipping it over and cutting the other side. But, this is seriously bad. I suspect the gears in the motor are stripped. Anyone have advice on troubleshooting this? Should I open the motor gearbox and check it?
