New Steppers Settings in Config.g



  • Hey guys! I just received new steppers that I purchased for my duet3d wifi upgraded rostock v3. I was wondering if anyone can help me on setting the right settings within the config.g file. The steppers I bought are 17M19-2004S, the specs are as follows:

    Electrical Specification
    Manufacturer Part Number: 17HM19-2004S
    Motor Type: Bipolar Stepper
    Step Angle: 0.9 deg
    Holding Torque: 46Ncm(65.1oz.in)
    Rated Current/phase: 2.0A
    Voltage: 2.8V
    Phase Resistance: 1.4ohms
    Inductance: 3.0mH ± 20%(1KHz)

    Can anyone lead me in the right direction, I would greatly appreciate it. Thank you!

    Juan

    I suggest you set the XYZ motor currents in M906 to 1200 or 1300mA and leave the microstepping at the default x16 with interpolation enabled.

    Thanks for the input! I have made the adjustments and they are now working nicely. The only thing now is that when I send G32 to do calibration the hot end lowers to about the mid height of what it used to do and starts probing with no success. For reference the steppers I had were the original 1.8deg steppers from Rostock v3. Any ideas?



  • you need to double the steps/mm in the M92 commands for the axis that you changed the motors on!
