Hello. A fellow friend of mine uses Lantek for his machines, which doesn't come in very handy with linuxcnc itself for a retrofitted plasma machine.

For example, the generated machine code looks like:
%1806
(JOB000476)
G71
N3 G90 D1 T1
N5 G00 X22.5 Y-1186.4
N7 M21

And surely linuxcnc doesn't read this.
What procedure can i follow to allow lantek to work with qtplasmac?
I'm thinking maybe i can change the M codes somehow in the post processor for lantek, to M3 to turn on the torch probe + on sequence, but i still need to imprint 'material number' in the beginning and some other start parameters.

do you guys have any suggestions?

Why not ask lantek to produce a post processor for QTplasmac?

My guess is money, Lantek will ask an arm and a leg to make a new post processor. I have seen quotes ranging between 5-10k$ for a post processor.

Then write a  filter so that linuxcnc modifies the Gcode file when it opens.
But QTplasmac already uses this technique so you would need to modify the existing QTplasmac filter.

It would be cool to be able to interface with high end nesting programs. Maybe the QTplasmac guys could develop an interface that allows extending the filter. Maybe ask in the plasmac section.
