Solved Extruder not working on new install (upgrade)
My extruder stepper motor just vibrates with minimal movement of the filament. Turning the mA up from 500 to 1000 makes it vibrate with a very fast, loud clicking but the filament moves. Previously working fine on my OEM Tronxy controller at 500mA and running smooth. I tried swapping motors and got the same. Tried the motor on the X axis and it worked fine. I tried swapping wiring with the same result. So, I'm sure its not the motor or wiring. config appears to be similar to many other working setups. This is a new installation replacing a working OEM setup. Did I get a bad stepper driver? I'm no expert at checking that but no obvious physical signs of a problem. I'm struggling with setting it up as an access point as well but will start a separate thread for that.
Machine: Tronxy X5SA
Stepper motor for extruder: LDO Overthemoon, 1.8deg, 1A. Tried the Tronxy OEM motors too.
Controller: Duet WiFi
Versions: firmware 2.02a, web control 1.22.6, server 1.22
I can't get config.g to upload due to poor internet connection so here is a text copy of my settings if it could be helpful.

I forgot to also say that I checked continuity of the motors and wires where were fine. But them working on other axis should have proven that as well. It is in a printed PLA case (Ocie's Box) with nothing anywhere near it that could be grounding it out. Unless there's something I'm missing in the firmware then I'm not sure what else to check. I don't know how to check the stepper driver itself.

is 100ma for the extruder correct? that seems a bit low.
maybe you mistyped and missed a 0
It looks like your E1 motor output is free. So you can try connecting it to the E1 output instead of E0, then change D0 in your M563 command in config.g to D1. Leave the heater wiring alone. If that fixes it then the E0 stepper driver is probably faulty.

E1 in his current configuration will also only receive 100mA. So it will result in the same problem.
I caught the E0 set at 100mA. It was a typo when I was trying higher settings and corrected it during my testing. My results described above were using 500mA (mA used with previous setepper driver and verified with a voltmeter) and 1,000mA.
I'll try using E1 output when I get home tonight.
E1 worked the same. I decided to break down the extruder and make sure nothing was mechanically causing this because it sure had a mechanical sound. I didn't find anything wrong but when reassembled the problem resolved. Who knows what could have caused the problem at the same time I upgraded to the Duet WiFi but I sure am glad it wasn't the Duet.
Thank you for the help. It's hard to believe the level of support for this product. I have already spread the word to almost everyone I know. I learned a little more through the process and for that I am very thankful. Now if I can solve the access point connection problem I'll be set.... until my next upgrade.
