Hi Dave,
Which file did you try to get? I just tried the CNC, worked OK. Files
are under files/TCI. Sometimes the link on the notice gets cutoff, and
you have to manually "paste it together". I'm still going through
Vector CAD/CAM for generating Gcode from PLC files, but if I can do the
PLC's, the Gcode is a no-brainer.
circle( 2.5400, 2.5400, 0.0000, 1.27350000, 1, 4.71238898, 1.04561007,
0.0000, 0.0000);
line( 3.1785, 3.6419, 0.0000, 3.1785, 7.7881, 0.0000);
N1050 G03 X0.1251 Y0.1434 I0.0000 J0.0501
N1060 G01 X0.1251 Y0.3066
I don't think I've got the right corresponding lines, but you get the
picture. Actually I just realized it, but the CNC file I uploaded was
output by Vector CAD/CAM in INCHES! So IT DID the MM->INCH conversion
for me (I think)! Seems the NC side of Vector has it's own inch/mm
parm (from the CAD side)! Yeah, FlashCut only likes it if I make it a
"G20" (inch)! Somehow, the I's and J's don't scale simply between
in/mm's! (Same problem I had in my code).
I'd like to see what you're up to. I had to make a few changes to get
the apertures from the header, but after I scaled them to integers (for
array storage), and figured out MM's, it worked (as well as the INCH
hand-coded RS-274D's). If I continue to use TCI, I think I'll through
in an MM->inch conversion!
I found out Gerber files have a polygon pad, as well as circular and
rectangular. Also an 'O' (OBROUND), which is probably an ellipse (or a
"stretched" circle? That's what I'm doing). Also a 'S', which I have
no idea what it is.
I did notice that TCI leaves off the '%' in front of some parms, MOMM,
OFA0B0 and FSLAX, possibly others. Not hard to edit the file. That,
and G04's are used for comments (I handled that one)!
