Well, dont I feel like a real idiot.........The red wire on the E0 connector that plugs into the Duet was broken inside the connector. I found when I was moving the connector to E1.....

@dc42 thank you

I have the wires directly connected together, and it was working prior to yesterday when I uploaded firmware again. I have also tried 3 separate steppers. Can I use extruder 2 to test? How do I activate that driver and set it up in firmware?

Look up M584 in the GCode wiki page.

That didnt help much.... anyway.
How is the duet output color codes? green/black=coil 1 and red/blue=coil 2?

hooked wires up directly, bypassing terminal block connector and still getting the "fighting" Could this be a firmware issue?

Unlikely unless you have set the acceleration or speed much too high. It sounds like a bad connection, faulty motor or a blown driver. Your reading of .887Mohms definitely means you had a bad connection or a faulty motor at that point. Can you test the driver by connecting a different motor to it, using a different cable?

just checked impedance on the stepper while still connected to the DUET. Coil 1 reads .887MΩ and coil 2 reads 1.2Ω. Think my driver is bad? I checked the stepper motor and both measure the same impedance.

My extruder stepper seems to be fighting itself (grinding and not turning) I have the stepper wired directly to the DUET board and double checked that I have each coil wired together, and that i have those coils wired to the black & green (coil1) and the red & blue(coil2) respectively. Any idea what my issue could be, I am thinking it is a firmware issue.

new issue….
when i load an .stl file and try to print, the connection terminates.

Added the S2 command to those files….
homed x - no error
homed y - no error
homed z and....

G28 Z

Error: G0/G1: insufficient axes homed

however when I use Home All
no errors and homes great

I added S2 to the homez file and seems to work fine now

thank you
