Extruder motor doesn't move
-
You'll need to alter the config manually to add non-standard mappings.
-
@phaedrux Could you please explain how to do that?
-
If you're using E2 that equates to driver 5 on the duex.
So in your M584 command, For the extruder drives you would list all the extruder that will be connected to the main Duet drivers and then add 5 for the expansion header.

@phaedrux Hi, my extruder motor needs 5V, while the Duet board output is 3.3V, I'm thinking of buying a breakout board like this:

Will it work? -

I'm not sure what you mean by this. The stepper motor drivers are constant current drivers. The rated voltage on the motor isn't a requirement.
-
@phaedrux I'm not using motor drive output, I'm using the expansion portion of the board, which is 3.3V output. But my extruder motor needs 5V.
-
@phaedrux Since I'll use the E2 of the expansion to wire my extruder motor, how to modify the config code to use the E2? I won't use the E0 and E1.
My config.g Driver code is below:
; Drives
M569 P0 S0 ; physical drive 0 goes backwards
M569 P1 S0 ; physical drive 1 goes backwards
M569 P2 S1 ; physical drive 2 goes forwards
M584 X0 Y1 Z2 ; set drive mapping
M350 X16 Y16 Z16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z400.00 ; set steps per mm
M566 X900.00 Y900.00 Z60.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 ; set accelerations (mm/s^2)
M906 X800 Y800 Z800 I30 ; set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout -

I already answered that I think.

Do you mean your external driver needs 5v?
-
@phaedrux Yes my external driver needs 5V, will this breakout board work for my case?

Can you link to your external driver?
