Ultimaker Original Plus - Inverting Feeder


Recommended Posts

Posted · Ultimaker Original Plus - Inverting Feeder

Hi,

I just modified my feeder so I could use 1.75mm, it's extruding pretty ok but in reverse... (the feeder isn't the one that comes with the printer).

So I have 2 questions for the experts out there...

To Invert the Extruder Motor, do i MUST compile a custom firmware?

And... If that's the case... What I need to edit on the firmware so the Extruder motors go inverted?

It's this on configuration_adv?

#define INVERT_E_STEP_PIN false

Thanks m(^o^)m

    I don't believe that is the correct value to change. It controls whether the step pin is active high or active low. do NOT change that one. It does NOT control the direction.

    You can do one of the following:

    Switch any 2 of the four wires will (permanently) reverse the direction of the motor thus no need for custom firmware.

    or change:

    INVERT_E0_DIR

    in configuration.h.and recompile.
