RFF3 Micro stepping

  • Hi everybody

    I'm using E3D Tool Changer with Duet Ethernet+Duex5, RFF3.

    I'm trying to enable microstepping 1/16 for extruders.

    At the moment the config.g have :

    M350 E8:8:8:8 C8 I0

    I tried:

    M350 E16:16:16:16 C8 I0
    M350 E16:16:16:16 I1 C8 I0

    without success (not enough extrusion)

    Did I made it wrong ?

    Do I have to configure an other paremeter?


  • did you change your steps per mm?

    the first would be ok
    the second should be
    M350 E16:16:16:16 I1
    M350 C8 I0

  • Stupid guy I am...Did not change step/mm !

    If you're using x16 microstepping you should enable interpolation for the quiet and smooth motor operation. Not much reason to use anything but x16 with interpolation on the Duet Wifi.
