I was going to call probotix today, but I've been sick all day. I have not looked to see if the led comes on when I trigger the torch in Mach3. I have not shorted pins 1 and 2 on the torch. If I'm feeling better I may give it a try.

The two black wires at the bottom of the second pic are the 5 volts.

I wired the torch trigger the way tech support told me to wire it, but I'm thinking they told me wrong. I wired the torch the yellow and black wires to the two pins marked yellow on page 2 of the manual. I'm thinking that one of those wires needs to go to the relay #2 switch marked yellow on page 2 of the manual link.

I'm still going to check everything before I do any switching of wires. I probably will ohm that yellow 2 relay on the left hand side of the board.
