Hello,
I have a prusa I3 pro x with a gt2560 board. I added a second mk8 extruder and installed a motor driver chip and got everything connected. I uploaded the I3 pro x duel extruder firmware. The problem I'm have is only extruder #1 turns. Extruder #2 does not spin. does anyone have any insight on this or a way to get it working?
Thanks,
Jason

Hi,Jason
Did you heat up all the extruders when testing extruder motors?
And you can refer to the following post to make some troubleshooting:
