Tesseract, I had the same problem initially with the extruder motor not working. It was firmware disabled because the temperature was not up the the minimum. There's a setting min temp and mine is set at 165 degrees. Once the print head is above that. E worked fine. I did as you did, swapping the E motor to the X drive and it worked; then I noticed a message in Repetier Host saying something like "below min temp". The min temp setting might be in Repetier but I thing it is Marlin.
Thanks for the info on Andy's firmware. I'll give it another try.
