Step Motor noise TMC2660

Cattalyste

Hello all,

I have a Duet Ethernet PCB 1.04 on an ender 5 plus (carthesian) and my firmware is : V3.1.1

These are my settings for the motors :

M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X79.42 Y79.46 Z800.00 E129.00 ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E1200.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E250.00 ; set accelerations (mm/s^2)
M906 X900 Y940 Z900 E960 I40 ; set motor currents (mA) and motor idle factor in per cent
M205 X8.00 Y8.00 Z0.40 E5.00 ;Setup Jerk
M84 S30 ; Set idle timeout

My printer is still very noisy (from the step motor), i already try to take a look on TOFF for the tmc2660 and yes when not moving it's more silent but not on movement.
For exemple on the X or Y axis I pull out the belt and make a moove to see if it was a mecanical problem with vibration but it's not that.

I use G1 X0 Y0 F3600 and then G1 X175 Y175 F3600 to test the noise. So a speed of 60mm/s that is not that fast for a 3d printer ?
So can I tweak something ? Or may I have to change motor to higher current one or with more/less inductance ?

Thanks you if you can give me some help !

tmc2660 do not support stealthchop. that is what makes silent moves.
only the duet maestro and the duet 3 support this.

Cattalyste

yes I use M569 P0 F# and i put from 1 to 3 dependant the axis but I don't touch the D parameter and let it on 2 (spread cycle)

@Veti
Stealthchop is only working at low speed if I'm right so we can't get silent step motor at speed like 40-50 mm/s ?

@Cattalyste said in Step Motor noise TMC2660:

Stealthchop

there is no stealthchop on the Duet Ethernet PCB 1.04

Cattalyste

@Veti

Yes but I want to see what I can do if there is no other solution. In the other hand I saw many creality user report creality stepmotor were noisy with duet board !

Cattalyste

(By other solution => changing board for maestro if that’s the only solution)

Veti

i run stealthchop2 on my maestro at 60mm/sec

however at that speed the noise difference is minimal.

@Cattalyste
Please check your X and Y steps per mm.

I have an Ender 5 Plus as well. X and Y should be 80mm/s each.

M92 X80.00 Y80.00 Z800.00 E394.22

I have a Hemera so my E steps are different.

I had an old Duet Ethernet and now the Duet Wifi on it. I would say both are very quiet even at 80mm/s.

Hello thanks I will try your step and a calibration cube ! Can I see your input for acceleration, speed variation, and current ?

(The noise will vary with motor specs and supply voltage as well)

Here are the values. Sorry it took so long but I don't check the forum often.

Please remember I have a Hemera so the extruder settings will not match your hardware. I am using the stock Creality X, Y, Z motors so the rest should be ok.

; Maximum values
M201 X500.00 Y500.00 Z100.00 ~~E1000.00~~ ; set maximum accelerations
M203 X6000.00 Y6000.00 Z300.00 ~~E6000.00~~ ; set maximum speeds(6000 = 100mm/s)
M566 X480.00 Y480.00 Z24.00 ~~E300.00~~ ; set maximum jerk
M906 X672 Y800 Z672 ~~E850~~ I30 ; set motor currents (mA) and motor idle factor in per cent
