Config for silent printing mode

pipersw

Hi.
I use a macro for reduce noise during printing when I need.
I use this macro :

M203 X3000 Y3000 ; Set maximum feedrate speeds (mm/min)
M201 X500 Y500   ; Set accelerations (mm/s^2)
M220 S50          ; Set speed factor override 50%

The printing moves are slower and quieter, but the travel moves and extruder noise are not quieter as I want.
The printer is in an enclosure, with Duet2wifi and latest RRF 3 beta firmware.

How reduce more the noise ?

You could lower the motor currents themselves.

Aside from that, you could implement some vibration damping to keep the entire frame and table and enclosure from acting as a reverberator.

Also, check that you have microstep interpolation enabled, by sending M350 without parameters.

Interpolation is enabled, I will reduce to 800mA my 1.68A motors.
I put some dampers under the printer. Damper on steppers don't reduce the noise.
