Lantek compatibility with QtPlasmac or Other LinuxCNC Interface?

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:
Code:
%1806 (JOB000476) G71 N3 G90 D1 T1 N5 G00 X22.5 Y-1186.4 N7 M21 N9 G41 N11 G01 X17.61 Y-1189.88 N13 G03 X26.745 Y-1182.155 I22.5 J-1186.4 N15 G03 X19.02 Y-1191.29 I22.5 J-1186.4 N17 G01 X22.5 Y-1186.4 N19 G40 N21 M20 N23 G00 X22.5 Y-998.9 N25 M21 N27 G41 N29 G01 X17.61 Y-1002.38 N31 G03 X26.745 Y-994.655 I22.5 J-998.9 N33 G03 X19.02 Y-1003.79 I22.5 J-998.9 N35 G01 X22.5 Y-998.9 N37 G40 N39 M20 N41 G00 X215.535 Y-945.15 N43 M21 N45 G41 N47 G01 X210.645 Y-948.63 N49 G03 X219.775 Y-940.905 I215.535 J-945.15 N51 G03 X212.05 Y-950.04 I215.535 J-945.15 N53 G01 X215.535 Y-945.15 N55 G40 N57 M20 N59 G00 X215.535 Y-1107.65 N61 M21 N63 G41 N65 G01 X210.645 Y-1111.13 N67 G03 X219.775 Y-1103.405 I215.535 J-1107.65 N69 G03 X212.05 Y-1112.54 I215.535 J-1107.65 N71 G01 X215.535 Y-1107.65 N73 G40 N75 M20 N77 G00 X315.71 Y-795.69

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.
