motor phase A may be disconnected reported by driver(s) 2
-
Hi,
I have an Ender 6 Core XY Printer and have just replaced the Creality Board with a Duet 2 wifi board. Took me ages before I realised that I had to swap the X and Y motors on the board to get it to Home Properly. But when I do issue a G28 I get the following messages:G28 XY
Warning: motor phase A may be disconnected reported by driver(s) 2
Warning: motor phase B may be disconnected reported by driver(s) 2
Also get a message "Response too slow"M115

Any clues?

@gsolomon said in motor phase A may be disconnected reported by driver(s) 2:
Warning: motor phase A may be disconnected reported by driver(s) 2
Warning: motor phase B may be disconnected reported by driver(s) 2Well that error is usually pretty accurate. So check your crimps on driver 2.

Driver 2 is driving your Z motor. Does Z movement work correctly?
-
Also be sure that the jumpers for the ZB connector are in place if you only have one Z motor.
-
Hi,
Yup thanks for that info. The jumpers on the seond Z socket were not in place. I was only doing XY so didn't realise that the Z motor was unable to move.
May I suggest especially with Core XY printers, that if a person is unable to get the XY gantry to move in the correct direction using the settings in Config.g, that they swap the X and Y plugs on the board and try again. It worked for me.But thanks for your fantatsic support. Definitely worth paying the extra dollars for a fantastic control board in comparison to that Chinese crap.

There's a whole section for setting up CoreXY motors
