I ran the g code single line by line and everything works perfect
But as soon as I cycle start it turns to custard
I’m thinking it’s either coms port speed or another crap control board
Though it’s weird that it does exactly the Same error at the exact same point every time

Are you using a macro in Mach3 to do the probing? Macros seem to have a problem skipping ahead when doing moves.
It also could be that you're probing too fast causing it to overshoot the switch. What is your feedrate on your G31 move? I would think this problem should show up on single step as well as run.

No macros
But there’s a weird jump in line numbers when I run in single line mode and step to the next line
As in the vid here

M06 is a macro. It's Tool Change in Mach3 T1 is tool 1.
Check the macro folder under the Mach profile and see what is going on in that macro.
I also see S500. That's.a spindle speed command. Usually not used in plasma.
I don't think these codes are in the Mach3 plasma post. Are you using this post?
