If you are talking about the EN, yes I have a jumper, which is the same as the C10 in the book. I have 5v there at the EN switch. That is one of the first things I checked. Nothing has changed about the lack of voltage from the pins. I would like to do some more troubleshooting if possible. I just dont know what to do next.

I will check.....what manual are you referring? All I have is the book.

I have a C10 board, identical to the one used in the book, so we should be able to find the problem since there are so many similar applications out there. Can anyone reading this thread off some advice?

This is a message I received from Scott at Mach Support:

The only time you should see a voltage change for the axes is on the direction pints when they change direction - unless you are looking at the pulse train with an O-scope, you will not see any voltage change on the step pins.  If you are seeing inputs activate when you ground pins, though, I do not think you are having a problem with Mach outputting signals - the driver either works or it does not, if you can see inputs it is sending outputs.  My question to you would be does that breakout board need or expect a Charge Pump signal, and if so do you have it configured?  The motors are getting power, but do they need any sort of an Enable signal before they will run?  Also, you may need to adjust the pulse width of your step and direction signals (which you can do in Motor Tuning), depending upon how sensitive your drives are...

I am not sure if the C10 board requires a charge pump signal to run.

I am going to have to take a break and try something different tomorrow morning. I have too many hours on this now. Thank for your help. I'm not sure what to try next.

It looks more like a software issue at this point.

There is only .050v showing when the axis is moving but there is 4.42v on pins on 10, 11, 12, and 13 which is always constant, never a change on those pins. What is this telling me? The port is functional but the software is not regulating the correct current? X, Y and Z show no current while moving.

Can you repeat what I should check now please? I am not sure what we are looking for now. I have spent so much time on this I can't remember what I have tried this time.

Pin 1 is on the long side far right. I have many pins causing changes on the diag screen. Scratch that, I am looking at it backward.

I was at the end of the cable instead of the computer. This made it easier to contact the pins.
