G0 Z4; Move to Pierce Height

You sure you arent just piercing too high? 4mm is a big gap (did you check the Plasma manual for recommended pierce and cut heights), try 0 for pierce and cut height
Seeing as Lightburn doesnt have any Z moves, thats the only (last, remote) difference I can think of

If your inverter cannot maintain such a big gap, the arc will die

 

What's your current settings?

$110=3500.000 ; X-axis maximum rate, mm/min
$111=3500.000 ; Y-axis maximum rate, mm/min
$112=1000.000 ; Z-axis maximum rate, mm/min

Max Rate limits top speed - but make sure your CAM operation's feedrate is sufficient as well (you type the number in there)

Set $11=0.010 ; Junction deviation, millimeters - one of the profiles you loaded set it to 0.020 in your last backup you posted. Dial it back to default

and set Steps per mm back to default:

$100=199.1 ; X-axis steps per millimeter
$101=199.1 ; Y-axis steps per millimeter
$102=199.1 ; Z-axis steps per millimeter

Then don't forget to check:

I am heading out, see you tomorrow

 

See above, would explain the plasma dying mid cut on hello world too

 

Matches the symptoms of classic wiring issue indeed (only 3 of the 4 wires making good contact, or coil pairs incorrectly identified) - we have a detailed FAQ page here: docs:blackbox:faq-identify-motor-coils [OpenBuilds Documentation]
