I recently build a DIY 3 axis router and am having issues with the software set up.I have a TB6560 chinese board powered by a S-350-24 being controlled by MACH3. In the MACH3 initial set up it has you input the Step pin # and the Dir Pin# for each axis that you will be running. I have a 3-axis set up and all of the pin numbers that the manual calls for won't get the motors to run. Depending on the set up the motors will whine or attempt to move but will not. Is there a way to determine the correct pin #s for each motor output without the manual?

I was able to get one axis to jog in both directions but somehow when I changed the pin settings on the other motors I disabled that ability. This makes me believe that my 4 wire Nema 23s are set up properly and are not the issue.

I apologize if I am asking these questions incorrectly or if I am providing incomplete information.

Thanks in advance for any help.
