My motors are fairly noisy when idle. The noise stops when I do M18. It's not noisy at all when moving.
These are the motors: https://e3d-online.com/motors-high-torque-motor
Datasheet: https://e3d-online.dozuki.com/Document/122/.pdf
The machine is a delta printer running on 24V. Only the axis steppers (no extruder) and endstops are plugged in at the moment.
I have tried this (from https://duet3d.dozuki.com/Wiki/Reducing_Stand-Still_Noise) :
M569 Fx P0
M569 Fx P1
M569 Fx P2
where x ranges from 1 to 15. F1 to F12 sounds like a loud noisy fan, F12 being the least noisy. Higher F-values produce a high-pitched sound.
I've also tried M906 I0 hoping that it will shut off the motor when idle but that didn't help. The I-value doesn't seem to have much effect on volume.
M569 C65968 P0 gives an error probably because I am on RFF >= 2.02; is there a F-value equivalent?
Config attached below. Geometry setup is still a work-in-progress.
Movement is extremely slow because of initial setup, but that shouldn't cause loud idle noise right?
Is it supposed to be so noisy when idle? It's unusable as-is because the noise is loud enough to be a distraction.
