Dual extrusion help



  • Ive upgraded the tevo little monster with a duet wifi and chimera hotend form E3D everything seams to work so far but the extruder for the Left side extrudes almost 10X the filament called for. I extrude 1MM and it moves 9.02mm normally I'd go in and change the steps per mm and be done with it but I don't know what I'm doing and I used a downloaded config.g file from a group of people that have already converted the LittleMonster to the duet wifi I just took it a step further by adding dual extrusion to the upgrade. what do i need to do to tune the 2nd extruder here is the config.g

    thanks in advance for the help

    Try changing these lines:

    M350 E32 I0 ; Configure microstepping without interpolation
    ...
    M92 X160 Y160 Z160 E837 ; Set steps per mm
    
    

    to:

    M350 E32:32 I0 ; Configure microstepping without interpolation
    ...

  • I changed the lines and adjusted steps per MM and it works!!!!!!! thank you so much
