Only cutting partial cuts

I’m trying to cut out some letters in 1/8" steel with my CrossFire and ViperCut 30i cutter. I have water table with slightly less than 5 gallons of water in it.
When I start my program, the plasma cutter fires and starts the first letter, but stops firing after a little over an inch of travel. It re-fires when it goes to the next cut and stops firing at about the same distance as the first one.
I thought maybe it was my .tap file, but I also tried it on one that I’ve already successfully cut and it did the same thing.
The plasma cutter is set on 30 amps and I’ve tried it with tip set using both shims.
Any ideas where to look or why it would be doing this?

The water table takes about 50% more water than that.

You should use the thin shim.

How fast is it running? Does it pierce through?

Try moving the clamp to the metal if it’s not already there.
