yes the grove was a bit more than just a J shape but that was
the simplest example that still had the basic shapes to test

the linear parts are a easy enough
those curves are the problem
there is no G-code to select a G02/G03 in the X,Y,A plane (saddle?)
so it has to ge programed as a few hundred small steps for each of the curves
also the control dosent seem to like to use tool radius comp when
the A axis is involved (it might work but nobody wanted to try it)
so the program has to be regenerated to make any tool offset changes

looks simple enough at first tho dosent it ;-)
