I'm also curious what kind of plasma cutter you are using?

Has increasing the arc_ok delay helped?

The fact that ignoring the Arc Ok causes it to work is telling. It tells me that there's something going on with that circuit, be it with "bounce" noise in the software, or with the physical circuit.

If increasing the arc_ok delay does not help, there is a section in the docs about contact load, which may help you as well.

arc_ok delay did not solve it.....same thing first pierce perfect, second pierce error & pause.

Is there any difference if you change the "pe" value to 0.0
From:

(o=0, ph=0.12, pd=0.2, ch=0.06, fr=100, th=1, cv=99, pe=0.2, jh=0, jd=0)

To:

(o=0, ph=0.12, pd=0.2, ch=0.06, fr=100, th=1, cv=99, pe=0.0, jh=0, jd=0)

Edit the gcode file, it is around 20 lines from the top.

One other thing that I see is that you are using really long lead ins and lead outs. The lead outs especially will be a problem because they require cutting over either something that was almost certainly already cut, or a bit of material that will have dropped out. For the gorilla file, a lot of the lead ins and lead outs get really close to a cut line for another part. And there are some lead ins and lead outs that overlap each other.
