New extruder stepper motor won't cooperate
-
I've been trying for 2 days now to configure my new extruder. I have a Troodon Vivedino 3D printer and decided to switch from the direct drive extruder (with a CSE14HRA1L410A-01 motor) to the OMG V2 S extruder (SST36C1080 motor). As the old stepper motor extrudes filament without any issues, the new one just vibrates and sometimes spins in one direction, and other times the other direction. I've checked the wiring about 30 times, and checked that the phase wires of the new stepper matches with those of the old steppers. I've also already checked that the wires are not broken anywhere with a multimeter. In the config.g file, I've switched from 688 steps pr. mm to 726mm (also tried 760mm)
M92 X80 Y80 Z400 E760and I have checked that the current is 85% of max current in the stepper motor (here I've also tried various values)
M906 X1200 Y1200 Z1200 E510 I30The driver does not seem to be broken, as the previous stepper still works fine. I've also tried different varieties of microstepping (8, 16, 32, 64, 256), but the internet told me to use 16
M350 X16 Y16 Z16 E16 I1The stepper motor works with both 24V systems and 12V system. The board is 24V. I am seriously out of options... what have I missed? I will paste my config file below:

@olenesheim (I've edited your post to make it more readable)
From memory, the Troodon Vivedino doesn't come with a Duet3D mainboard, so I think you have a clone Duet board, and the official support that I can offer is limited. Also, from your config.g, you appear to be running RRF 2.x firmware, which makes it a bit harder to support you as we have mostly moved on to RRF 3.x now.
The best link I can find with information on the motor is here https://www.my3dtech.com/OMG/sst36c1080-motor/, and links to here for the manufacturers info https://jp.aspina-group.com/ja/products/motors/cat01/001/
It looks like the phases should be Brown/Orange and Red/Yellow, but it does seem that wiring and phases are correct from your tests.So I'd think it's more likely a configuration problem. Looking at the motor specs, the only thing that jumps out at me is the phase inductance, which is 3.16mH. I think the inductance for your motor is 1.41mH. See here as to why inductance is important. This probably means you can't run it as fast as the old motor, and what you might be experiencing is that the step rate is too fast for the motor. What commands are you sending to the Extruder to test it? Your current settings are:
M566 E250 ; maximum instantaneous speed changes (mm/min) (jerk) M203 E3200 ; maximum speeds (mm/min) M201 E3200 ; accelerationsI would try halving all of these and test again. If that still doesn't work, reduce acceleration even more.
