Help me! Pancake Steppers don't work....
-
Good morning, I've just finished mounting my new Bondtech X2, but the two original Bondtech pancake don't work....they make this noise, they just vibrate but they don't work....the connections are correct....what's wrong? Mother board Duet 2WiFi. Tried also with original E3D Pancake and do the same. "Normal" NEMA17 works great
here's the link for the MP4 I shot:
Here's a snippet of my config.g

- How have you tested that you have the motors are connected correctly?
- What is the specification of the pancake stepper motors?

I've tried to connect a "normal" Nema17 (not pancake) with the same connectors and it works fine.
Theese are the specs:

Yes, but how do you know that you have connected the pancake stepper motor phases correctly? See https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Connecting_stepper_motors especially the bit about identifying stepper motor phases.
Theese are the specs:
The rated current is 0.7A per phase. In your M906 command you have set 0.8A peak per phase. As the Duet 2 doesn't do standstill current reduction, I suggest you reduce that to 0.7A per phase.

Phases are correct because I've checked them with a multimeter (and if I plug a non-pancake stepper in the same socket it works). I've also checke the stepper pinout correctness with the multimeter
Tried to change current but stil doesn't work...isn't there some other parameter? As I told you even an original E3D Pancake doesn't work...it looks something related to the....well...pancake....
EDIT
The E3D Pancake works....I really can't understand because the wiring is ok -
@thedragonlord Make sure the connector to the driver is making contact to all pins on the driver output connector. I had that occur and a wire had a bad crimp.

they do correct contact

@thedragonlord SOLVED!!! The pinout showed in the Bondtech datasheet is WRONG the phases sequence in the socket aren't A+ A- B+ B- as showed BUT A+ B+ A- B-
Sorry for the disturb guys and thanks for the help! You can mark the post as SOLVED
