[BUG] Screaming stepper motors with stock drivers #56

Closed gitmacer closed 5 years ago

gitmacer commented 5 years ago

Describe the bug Always when the motors are powerd with this firmware they are screaming relativly loud to hold its position and while moving. As soon as I stop the motors the sound will disapear. For now I switched back to the stock firmware where the sound is a lot quieter till I know how to fix that.

To Reproduce Steps to reproduce the behavior:

  1. Start printer
  2. Move axis by any value
  3. hear error

Expected behavior The same noise level as the stock firmware

Printer (please complete the following information):

For the stock drivers version of this firmware, the usual A4988 configuration is in use. Just like on Anycubics official (1.1.0) firmware. Hence this is not a specific issue of this particular firmware but more likely of Marlin 1.1.9 in general.

Anyways, I've never had anyone else report noisy stepper drivers when switching to this firmware so I have no idea what could be the issue here. Please head over to the official Marlin firmware repository and ask there.
