Hi. I bought a makerbot 'struder controller and mobo about 6 months ago. Initially had some trouble getting it running, so shelved it. Now I'm playing with it again, and have been making some progress. But! The h bridges on the extruder don't seem to be working at all. I've successfully loaded the controller tester on it [1] and the MOSFETS drive a motor just fine. The LEDs associated with the H bridges light up, but there's no voltage at the terminals.
Oh, I also tried the drive-a-stepper-with-your-extruder trick [2] -- also no dice.
Any thoughts?
Thanks in advance,
Liav.
