Ok, just spent the last 2hrs getting the volcano installed, and it is working. However, my extrusion is not? The nema motor is not moving when I command it too. What is the best way to trouble shoot what is going on. I can heat, I can move, x,y,z. Fans are all good, just no extrusion. I can pick up a 0.9° stepper tomorrow at lunch, but no clue how to modify the firmware. Let me know. I'm thinking I pulled a wire free internally to the stepper motor when messing with the loom.
