The motors are not moving. I feel the only thing I have accomplished is getting the jumper from the gnd to 5v moved.

Not sure what to do next. Multimeter from bob to driver or parallel port test?

When nothing makes sense, start over and re-examine even the most basic details for mistakes.

In the picture of your bob you have wires red,black,green,red,... on pins 2-9 and their commons. What exactly are the red, black and green, wires connected to?

But even before that, we have yet to determine definitively if Linuxcnc is even comunicating with the breakout board/parallel port combination. Try connecting a jumper wire from one of the inputs to 5v on the bob, can you see that input change state in Linuxcnc when you do that? If not try the same thing only to ground instead. if you still don't see any change. Then you either don't have the parallel port address right, or Linuxcnc isn't communicating with the port for some reason (such as are you sure the port is address 0x1008 and not 0x1000).

Once you've confirmed you have signals going to and from the bob, then you are ready to delve deeper into why the steps are not getting to the drives.

Those wires go to the drivers. They are wire up like Joe stated above.

Do you mean jump the input pins to 5v? Look at the lights in the hal config in the linuxcnc?

Thanks.

OK I have 5v at the drivers.

I ran the parallel port tester. When I used address 0x1008. I was able to see pin 10 go green and red when I pushed my estop button. It is wired pin 10 to 5v. Estop is nc.

So if it was me I'd do this:
pull up stepconfig and create a new profile.
Work through step by step:
linuxcnc.org/docs/html/config/stepconf.html

On Step 5 leave everything as "unused" except for 2 and 3. Configure them for the X axis.
Put your 0x1008 in the box where it's asked for.
On Step 7 put the data in for your motor. If your dip switches are like mine, then microstepping is 2. Most motors are 200 steps per revolution. The rest is determined by your machine - what pulleys or lead screws it uses etc.

Test that axis. If it moves, then fine tune the numbers until you're happy.
If it doesn't, then hit the back button until you get back to step 5. Check the invert box for x-step, then go forward and test it again.
If it works, go back to step five and add the Y axis on 4 and 5 - repeat one axis at a time.
Leave the extra stuff like limits and e-stop for after the x/y/z are working.

None of that worked. I am tired of messing with the pci card. I am looking for a Dell with a built in parallel port. There are a couple on craigslist at a reasonable price. I hope it will work better for me. Thanks for all your help Joe.
