Improvement request: labeling of stepper motors #5

Closed dirkx closed 4 years ago

dirkx commented 4 years ago

Would be nice to mark pin 1 of the stepper connectors and the 1A,1B, 2A, 2B on the top of the board.

I don't follow completely. Could you markup a screen shot?

12/AB labels - as these are often on the datasheets with wire-colours of the steppers.

And a pin 1 marker - as a lot of connectors have such a marker too.

Sorry for the odd format - but I lack editable versions of the PCB and Creo files.

Version 2 labels the connector with wire colors. They should match the recommended motor. Both wire colors and coil names on alternate motors could have reverse rotation.

That already helps a lot. In general the A/A and B/B moniker of the driver chips works well too. As most motors have that in their documentation with the wire colour - with a fairly stand A coil location relative to either the wire egress or the triangle on the housing.
