M542 driver - motor vibration at low speeds

[birchy]

you've probably been at this longer than me anyway.

Linux - probably...CNC - almost definitely not...

I'm beginning to think that the resonance is a feature of the cheap setup rather than a fault? I'd be interested to see what Jonathon and John S have to say about this, as I know they use these drives and motors on a regular basis. The motor is bolted to 200Kg+ of metal so I'm surprised there's any noise. I'm thinking I might need to isolate the motor bracket from the main machine using some rubber sheet. Having said that, the issue is with the motor setup rather than something mechanical. Pics for reference:
