Hey guys, I ended up just buying Simplify3D and noticed (don't think it's related) that my extruder motor is no longer turning during a print. When I heat up the hotend and manually turn the gears plastic is extruded no problem. When I try to print or command the extruder motor to extrude it simply does not turn and I don't think I'm getting any failure or error messages in the terminal. All the other motors work just fine during a print.

I do notice that I hear a sound coming from the extruder motor when I command it to extrude a very soft whine tone that lasts for the same amount of time it should be extruding.

Things I've tried:
Extrude via Octoprint
Extrude via USB connection to PronterFace
Extrude via USB connection on Simplify3D
Measuring each stepper driver trim pot setting (0.38V Makerfarm i3v 8 inch manual recommends 0.39V)
Measuring the 12V bus from the power supply (11.74V)

If anyone has any ideas of things to try next that would be much appreciated!
