just produce a high pitched noise

I do not have the source, but IMHO this sketch is consistent with Wiki and have the information about special notation D2W uses. The rest is up to the reader.

Don't want to seem boring, but according to
"On Duet 2 WiFi/Ethernet these are labelled '2B 2A 1A 1B' on the back of the board, and on the wiring diagram. The '1' and '2' refer to the coil or phase, the 'A' and 'B' refer to the positive and negative."
"+" and "-" are currently reversed.

@gnydick said in Request change to wiring diagrams:

At the very least, you could put a comment on the wiring diagram that tells you 1 & 2 are the different coils and to NOT map A & B to the motor diagram's A & B.

For Duet 2 this suggestion looks reasonable.

Sorry for crossposting, actual info for Duet2 + Ender 3 LCD here: https://forum.duet3d.com/post/207704

Just a little compilation of previous info for Duet 2 (according to RRF 3.2 Pins_DuetNG.h) and Ender 3 LCD connected via EXP3:

The only one thing working not as expected - M300 S3nnn does not change frequency in my setup. Though I did not checked it with stock...
