re: IJK interp

Alan,

The most common IJK seems to be the SIGNED distance FROM the CURRENT
position TO the arc center. And is usually incremental FROM the
CURRENT position. As you used in your example, which is consistant
with most Fanuc 'flavors'.

G00 x0y0
G01 x1 F45
G02 x1 y0 I0 J1 (2 unit circle dia. centered at 1,1)

Not too early, just don't want to "release it" yet...

P.S. I may be brain dead here, but what is that 67.5?
