It did not make difference. incorrect steps remain in this mode.

jay_s_uk

you've got the drivers set to 400 steps per mm, and i believe originally, you were looking at using 3200 steps per mm.
have you tried switching back to that?
That should reduce the amount of noise you are hearing

It was actually the previous setup. The sound and problem with the same setting remained at 3200 settings.

The reason 400 setting is on, I have added a 1:40 Gearbox. Therefore, 400 was an appropriate setting.

The new setup;

M92 X114.29 Y114.29 Z114.29 E274.00                   ; set steps per mm (400/140) * 40 = 114.2857 ; 400 step per rev ;; 140 mm one rev pulley ;1:40 ratio gearbox

However, It could be higher steps/mm with smoother settings variation, I would try. But Due to the high gearbox, it needs high-speed rotation to need on the motor. So, the lower step is lesser the signal density.

But the actual issue is not noise. Hearing noise is just a sign.
The actual issue is within the recommended P values noise into the signal output of the breakout board. I can connect an oscilloscope to prove it. Some missing steps cause less travel than the actual distance.

The Motor Control Problem resolved! ( interns of calibration and successful machine move ) ( But I still need your valuable help on bed calibration Should I open a new thread?)

Thank you very much for all your contribution.

Solution: I have just upgraded to the latest beta Firmware and DWC.

Conclusion:
But the configuration remains as (P 2-3-4) I was using. The recommended P 5-6-7-8 values causing problems. If it is not an issue with "Duet 2 Wifi r.104" It is something with the firmware I believe.

The Problem with recommended configuration P-values causing missing steps and noisy move. Each axis even the same amount moves command, they move different distances.

By the accidentally found settings and new Firmware update problem is over!

So this is the code that is working so far:

; Drives
M569 P5 S0 R0 T3:3:5:0; Extruder drive 0 goes Forward
M569 P2 S1 R0 T2.5:2.5:6:6; X: A drive 1 goes Forward
M569 P3 S1 R0 T2.5:2.5:6:6; Y: B drive 2 goes Forward
M569 P4 S1 R0 T2.5:2.5:6:6; Z: C physical drive 3 goes Forward

M584 X6 Y7 Z8 E5; set drive mapping
M350 X1 Y1 Z1 E1 I1; configure microstepping without interpolation
