Re:Gcode

Ballendo,

Thanks for the examples. I can see some uses now. I inscribed three
circles in three faces of cube, and generated code for it in VectorCAD.

(three circles 9/2/00 alm)
N05 F5
N10 G00 X0.000 Y2.000 Z3.500
N11 G19
N12 G03 Y2.000 Z3.500 J0.000 K-1.500
N13 G00 X3.500 Y2.000 Z4.000
N14 G17
N15 G03 X3.500 Y2.000 I-1.500 J0.000
N16 G00 X3.500 Y0.000 Z2.000
N17 G18
N18 G02 X3.500 Z2.000 I-1.500 K0.000
N19 G17

I added the G17/18/19. I get how it works now. Doesn't seem like MAXNC
- PRO (drives my Sherline) understands G17/18/19. Thinks they are all
in XY. Does anyone know if the DLX version (4-axis cnc) does (I think I
can upgrade)?

CNC Pro does (http://www.yeagerautomation.com/specs.htm), so that might
be a solution. I am still using 4-phase drive, don't know if CNC Pro
supports it. For what I am doing now, simple XY arcs are fine on the
Sherline. But later...
