Ok out of the blue my extruder stopped extruding. This is what I have done so far.
Swapped stepper driver board with a known good board. This did not work.
Plugged extruder motor into x axis driver and find the motor works fine.
Plugged known good motor into extruder driver on ramps board and no go. Hmmmm
I have a spare ramps board. Swap the spare ramps board and no changes.
Change E0 to E1 in pins.h and this did not work. But to verify I plugged extruder motor again into x axis driver on ramps and the motor worked. Connected x motor into E1 and no go.
I hope the above makes sense.
In short each individual component works fine. E0 and E1 do not seem to function regardless of what driver or motor are connected. I thought for a moment the Arduino could be the problem but I find that unlikely since I'm seeing this problem on both E0 and E1.
If anyone has an idea I have overlooked as far as shooting this goes please share with me. Or if you have dealt with this your self.
