Noise on Power Up (steppers)

Recommended Posts

Posted · Noise on Power Up (steppers)

Hi folks

I got Marlin1.1 on my UMO+.

Since Marlin the UMO make short loud noise on booting up (about half a second).

sounds like turning on all stepper-coils at the same. brrrrrrrmmmmmm!

Why? And how can I turn this off?

Thanks

Sounds like a bug in Marlin 1.1 - especially if it didn't happen with the older release.

You could try upgrading again to the latest release: 1.1.4

Also check on the Marlin Firmware Forum if its been reported as an issue:
