TMC reports error: ... reset=1(Reset) OR CS_ACTUAL=0(Reset?) OR SE=0(Reset?)

(TMC drivers - Klipper documentation)

can you please let me know where I can find these errors if they show up? I have already hashed the stealth chop and can hear the skipping sound but it doesn’t extrude or retract.

My guess is it’s wired incorrectly, or you have a bad connection or wire. I can’t offer any other help. The info at the link is the best information available.

The Manta M8P pins for motors are wrong in the manual. See this.

I have the same issue but can’t access what you’re linking to…

Hello @Buckeyeprof !

If you can’t access, then it is not the same issue.

Please open a new thread with all the required information.

My issue was the same exact issue and I was trying to follow the directions in this thread to fix it. However, when clicking the link in George’s comment that should have lead to a corrected pinout, there’s nothing to view.

So, I replied to George to let him know the link doesn’t contain what was promised or I can’t access it.

See Manta-M8P/Hardware/BIGTREETECH MANTA M8P V1.0 PinOut.png at master · bigtreetech/Manta-M8P · GitHub
Verify your motor connector against this pin-out

The errors that @George mentioned have been fixed in the Manta documentation.

That was the pinout I had and it’s not very informative. I assumed 2B 2A 1A 1B was the same as B- A- A+ B- on my steppers. But it’s actually B+ B- A- A+.

Thankfully the TMC2209s protect themselves from incorrect wiring so I was able to trial-and-error my way to the correct wiring.

You will typically find this 2A 2B 1B 1A or B1 B2 A1 A2 on the printerboard. The meaning of marking is not uniform, but I dare say:

  • The first character typically is the coil / phase numbering (Very important, since mixing the coils has a good chance to destroy the stepper)
  • The second character is the polarity (less important, since it can be reversed in the software)
