Arc Starts, Arc OK good, No motion

Hi,

Hope this is in the right spot. I have an old, DIY cnc table i've converted over to LinuxCNC with a Mesa 7196e and have had good luck getting everything moving so far, but going into my first cut circle i've run into some issues.

I can get the plasma to turn on with Pulse, i read Arc OK which i would expect. The machine probes the float switch and starts into the cut, pierces, then just stays where its at and doesnt move, with the arc still ON.

Any ideas?

More info,
What config are you using?
What THC?
What mode ?
How is everything connected ?

What config are you using?
- Running PlasmaC (not sure if this is the question your asking)
What THC?
- THC Disabled, but have a THCAD-10 connected, waiting for my external resistors to take my 1:1 ratio down to something usable
What mode ?
- Running in Mode 1
How is everything connected ?
- I'll have to get a block diagram done when I get a few free minutes.

I was able to do a dry run and it moved just fine with the plasma turned off and disabled.

Do you have wiring going to the plasma machine for the ARCOK signal ?
Mode 1 requires ARCOK signal from the plasma cutter, not synthesized by the THCAD.
If you do not have that wired, changing the mode to 0 should get you going.

It's wired and as I mentioned in the first post I do see on the dashboard interface a good light for ok arc.

That does not answer any of my questions.
