What is your Duet2Wifi Extrusion speed?



  • What setting are you using for extrusion rate/speed?

    Im having problem with too much extrusion and extruder is eating away fillament then not moving because of a divet.

    I bumped my m92 from E1025 to E700.

    heres my settings;
    ; Drives
    M569 P0 S0 ; Drive 0 goes backwards
    M569 P1 S0 ; Drive 1 goes backwards
    M569 P2 S0 ; Drive 2 goes backwards
    M569 P3 S1 ; Drive 3 goes backwards
    M671 X421:-111.5 Y162:162 S5 ; leadscrews at mid left, and mid right
    M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
    M92 X80.00 Y80.00 Z400.00 E700 ;E1025 ; Set steps per mm
    M566 X600.00 Y600.00 Z12.00 E120.00 ; Set maximum instantaneous speed changes (mm/min)
    ;M203 X9000.00 Y9000.00 Z180.00 E1500.00 ; -origional- Set maximum speeds (mm/min)
    M203 X12000.00 Y12000.00 Z800.00 E800.00 ; Set maximum speeds (mm/min)
    ;M201 X3000.00 Y3000.00 Z250.00 E12000.00 ; Set accelerations (mm/s^2)
    M201 X3000.00 Y3000.00 Z250.00 E700.00
    ;M906 X1250.00 Y1250.00 Z1250.00 E1250.00 I30 ; -origional- Set motor currents (mA) and motor idle factor in per cent
    M906 X800 Y800 Z800 E800 I30 ; Set motor currents (mA) and motor idle factor in per cent
    M84 S30


    See how thick the extrusion is and supports are suppose to be lot thinner.

  • Not teaching you to suck eggs...
    What extruder are you using? Bowden or DD?
    Have you done all of the calibration? Feed and flow rates?
    This is the process I use https://mattshub.com/2017/04/19/extruder-calibration/
    I think its for Marlin fw, but the principle is the same.

  • -Bowden- Titan Extruder Clone with Duet2wifi



  • Titan with a 1.8 stepper should be in the 400-420 step range and double that if using a 0.9 degree stepper motor with the 16x microstepping. I have a bondtech BMG clone extruder on my ender 3 with a 0.9 degree pancake stepper motor...my esteps after calibration are 846.90. Also your acceleration is very high for your extruder which could also be causing issues. I have the max speed and acceleration for my extruder at 3000.

    M350 X16 Y16 Z16 E16 I1 ; Configure microstepping with interpolation
    M92 X80.00 Y80.00 Z400.00 E846.90 ; Set steps per mm (gregs wade was 604 steps)
    M566 X500.00 Y500.00 Z30.00 E600.00 ; Set maximum instantaneous speed changes (mm/min)
    M203 X10800.00 Y9000.00 Z300.00 E3000.00 ; Set maximum speeds (mm/min)
    M201 X1000.00 Y1000.00 Z500.00 E3000.00 ; Set accelerations (mm/s^2)
    M906 X700.00 Y700.00 Z700.00 E960.00 I30 ; Set motor currents (mA) and motor idle factor in per cent
    M84 S30

    EDIT: I see you commented out those high speeds...I didn't see the semi-colons at first glance.
