Hi, Building myself a little router with the following parts and I'm having issues with the spindle control. I am running mach 4 also.

Currently I can get the software to turn on the counter clockwise rotation but not the clockwise. I have wire the CW direction up to the relay as shown in the diagrams but when I click these it doesn't seem to do anything.

I'm not sure exactly what pin should be controlling this relay also. I believe it may be pin 14 but if I set that in the output on the mach 4 software to pin 14 it is always on and will run in forwards with the software enabled or disabled until I take the output off.

Any advice is appreciated and thanks for your help.

Best Regards
