X/Y movements reversed. Kind of...

Hello chaps,

So I've got to the commissioning/calibration phase of my D-Bot coreXY build using a Duet 0.8.5 and everything seems OK, except for the X move commands resulting in front/back motion, and Y moves resulting in left/right (via the web server).

I've tried swapping the X/Y connectors on the board, but that makes no difference.
They're wired correctly according to all the diagrams, so I'm a bit baffled here.
I'm running DC42's RRF 1.14 along with the CoreXY sys config.

Cheers for any advice, and let me know if you need more info.

You might have to tell one of your motors, either X or Y to run reverse to get the motion correct. On both my CoreXY Duet printers it looks like the following:

M569 P0 S0;							; (X axis) Drive 0 goes reverse
M569 P1 S1;							; (Y axis) Drive 1 goes forwards

This makes the X move from left (0) to right (300) and Y moves from front (0) to back (300).

Thank you very much. That sorted it out

Well, the other way round in my case.

M569 P0 S1 ; Drive 0 goes forwards (change to S0 to reverse it)
M569 P1 S0 ; Drive 1 goes forwards

ED:
Actually, they should be the same as your settings, but I forgot that I hadn't switched the plugs back to normal
