M542 driver - motor vibration at low speeds

[EddyCurrent]

Sorry for assuming you used Mach3, from my limited knowledge the settings appear to be okay, you've probably been at this longer than me anyway. I would be into trying a different motor and swapping the M542 just to eliminate those from the equation. If you think it's maybe a screening problem why not run a temporary cable between the motor and M542 that is well away from everything else. There was another thread a few weeks ago about rubber mountings and I suggested using heatproof silicone sheet like this SILICONE RUBBER SHEET 200MMSQ, 1,1.5,2,3,4,5,6,8,AND 10MMTHK | eBay, but the opinion was to bolt the motors straight onto metal.

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:

As a matter of interest are you using ball screws or the original screws? Big credit to the neatness of the panel. ..Clive
