Control Cabinet Wiring

Greg,
The relay diagram has the polarity of the supply the correct way round for the diode and the transistor, you have them reveresed in your first diagram.

Your problem with reversing the spindle is that there is only the one "spindle ON/OFF' output from the BoB you have chosen so it cannot automatically respond to separate FWD and REV start codes from the G-code.

Hi Kit

Thanks for getting back to me.
I am trying to follow previous diagrams but do not really understand.
Here goes what I thought happens.
There is a relay on the BoB that sends a signal to the Keyes Sr1y if you want to switch motor direction. In the NC position, it is wired for Forward and in the NO position, it will use reverse.
Not really sure how other than it is controlled by Mach3.
I was hoping someone more knowledgeable might understand and help.
