[Swansea Hackspace] Stepper Motors

[Gerrit Niezen]

Yes, buzzing motor in my case meant the current limiting on the stepper motor driver was configured incorrectly, meaning it required a higher voltage and current to run than what was expected.

I'm not fussed about the feedback, buzzing motor usually means bad config.  Look at the Gerrit's motor, and he sorted that, was just configured wrong when we had the attempt at it.  I believe its working fine now since he looked at it again?
