Motors loud when running

mokash

Hi everyone, I recently converted my Voxelab Aquila (ender 3 v2 clone) to a duet 3 mini 5+ using the ender 3 guide and now
my motors a making a very strange sound. They aren't loud like the A4988, they are loud in the sense that they sound wrong. They sound like air leaking from a tank, but with a shallow high frequency beat. Its way louder than my other boards and sounds very wrong like something is not the way it should be.

The sound is only there during movement, the motors are dead silent during idle. Iv'e tried different modes with similar results e.g. M569 D0-3 ; M350 I0 and I1; and different micro step configurations

I did have issues with the 5v rail because Creality decided to mess with all wire colors on their version of the bl-touch but once I sorted it the board worked fine. I doubt I caused any damage but worth mentioning.

What firmware version are you running? You should probably be running 3.3 RC2 to take advantage of some bug fixes for the mini5 drivers.

You can take a look at the stepper tuning page here
