Maybe on the back of the PCB if you can't see any exposed pins on the top.

You kind of already have tested one of them pin 10 with your e-stop.

Depending whether you have them configured for pull up or pull down, connect them to ground or 5v, and watch for the indicator to change in Linuxcnc.

They are set up for pull up.

Then you would connect them to ground.

Something else you might be able to try, is connecting a wire from your step/dir output pins to input pins (disconnect them from the drive first). Then check to see if you can see the input being triggered by the output in Linuxcnc.

Ok, I got the multimeter out. I have 5v all the way out to the drivers. I am thinking the drivers are not working right. I will email the company and see how to trouble shoot them. I would like to thank everyone for their help. I sincerely appreciate it. I hope to be making sawdust soon.

You said you've got 5V to the drivers. Did you continue up the chain - put a multimeter on the outbound side of the drivers (The A+ A- B+ to see if the signal is going out, and then again at the motors themselves on the four wires there?

And you know you've got the 5V coming from the board. That's for the signal, but did you test to see if you've also got the main power going to the drivers from your 24-40V power supply? That's the power that will actually spin the motors.
