If there's nothing better on linux which outputs our NC format, and it is
considered our best bet, I can whip out a couple of pages of translation
now and then.
The site does say >>>
File / Export NC-ISO
Ausgabe der NC-Bearbeitungscodes in Datei /tmp/pp.iso.
Weitere Postprozessoren auf Anfrage.
<<<
i.e. Output of NC-machining codes in file /tmp/pp.iso.
Additional postprocessors on inquiry.
Are ISO gcodes similar to, or directly mappable to, our unextended set?
If so, it shouldn't take too much to convert a pp.iso, using a bit of
Awk, if their developers are busy.
( In an idle moment, I lashed up the beginnings of a gcode translator to
help me understand posted code. It converts:
G90 G81 G98 X4 Y5 Z1.5 R2.8 (Drill one hole)
G91 G81 G98 X4 Y5 Z-0.6 R1.8 L3 (Drill three holes)
G83 X1 Y1 Z1 R1.8 L5 Q0.100
G3 I5.00 J6.00 K7.00
to:
absolute drill retract_to_prior_z X4 Y5 Z1.5 retract_to 2.8 (Drill one hole)
relative drill retract_to_prior_z X4 Y5 Z-0.6 retract_by 1.8 rpt=3 (Drill three
holes)
peck_drill X1 Y1 Z1 retract_by 1.8 rpt=5 peck=0.100
arc_ccw_to centre_at 5.00 6.00 spiral_to 7.00 ### May be inaccurate
###
So a bit of gcode dialect translation doesn't sound difficult.)
Gene, if you need a couple of short sections translated, to gauge
whether this is the tool to seriously go with, then just point them out,
and I'll have a go at 'em.
