Driving Servo Motor with Duet3d



  • Hello Everyone!

    I have a duet3d driven cartesian printer which worked superfine with high quality prints using stepper motor.
    Recently i switched to servo motor (JMC IHSV57 integrated AC servo motor). I have some problems driving the head due to the parameters.

    Can someone help me with the duet parameters in M569 command with the above graph ?

    currently i use: M569 P7 S0 R1 T2.5:2.5:7:0

    The motor moves smoothly but the position feedback is high and the overall movement of the head is not normal. It always tries to correct the position and if i give another command for movement, the motor stops because of driver overload as the previous correction of position is not completed yet.

    Has anyone used these motors with duet before ?
    Thanks for the help.

    Cheers,
    Phani

    M350 X1 Y1 Z1 I0 ; Configure microstepping without interpolation

    M92 X200 Y97 Z4000 E94:94 ; Set steps per mm

    M566 X2000 Y80 Z15 E20:20 ; Set maximum instantaneous speed changes (mm/min) - Jerk speed
    M203 X4000 Y150 Z300 E9000:9000 ; Set maximum speeds (mm/min)
    M201 X1000 Y40 Z250 E1000:1000 ; Set accelerations (mm/s^2)

    Any Suggestion for correction ?
