Hi everyone.
I try to turn my Pro B into a dual extruders one.
I've the GT2560 rev A+ board.
I've modify the "configuration.h" and "configuration_adv.h" files this way :

#define EXTRUDERS 2

But, unfortunatly, the E2 motor don't turn. Even in manual mode nor when I print with this extruder.
I've swap cable, motor, driver. Nothing change.

Have ideas for helping me ?
Thanks.

Remi.

You need to change the value of the pins.h also
You can try to upload the firmware for PRO C

I have the same problem, I'm not getting any power from the GT2560 for the second extruder, both hotends works fine, very annoying and still looking for a solution, will be keeping an eye on your post for a solution, good luck

probably just a silly question but have you installed a stepper driver for E2 as the pro b only comes with 4 stepperdrivers
