Inverting Motor direction

MaxGyver

I am not sure if this is related to the beta Firmware. (I am on 3.2.0-beta3)
For some time I have not been able to invert the motor direction by changing the S parameter in the M569 command. First I thought this was a bug in the current Beta, but this seems to be persistent.

Since you're specifying CAN boards in your config I presume you're using a MB6HC + EXP3HC. If that is the case, then you partially specify the wrong drivers in M569. Try something like this:

M569 P0.0 S1                                 		     		; Drive 0.0/Z1
M569 P0.1 S1                                     		 		; Drive 0.1/Z2
M569 P0.2 S1                                		     		; Drive 0.2/Z3
M569 P0.3 S1                            		        		; Drive 0.3/Z4
M569 P0.4 S1                               		       	; Drive 0.4/Y1
M569 P0.5 S1                              		        		; Drive 0.5/Y2
M569 P1.0 S1                              		        		; Drive 1.0/U
M569 P1.1 S1                             		         		; Drive 1.1/X
M569 P1.2 S1                                     		 		; Drive 1.2/E0
M584 Z0.0:0.1:0.2:0.3 Y0.4:0.5 U1.0 X1.1 E1.2 	; set 4 Z drivers and add one U driver -> Must come earlier than M350,M906,M92, M201, M203, M208, M350, M566, M574, M667 and M669
