Cutting Tetrix gears

Thanks.

The slitting saw wouldn't be my first choice of course. but the code he's using to generate the path is fairly straight forward and should be easily adapted to any cutter.

I quickly tried converting it to the Centroid but it's complaining. I re-numbered the variables but the sub-programs are handled a little differently. Might take a little more to sort it out.

Being able to cut various pitches and tooth count of gears without the expense of many specialty cutters is interesting. Being able to give the kids a programming exercise is a bonus.

It would be very easy to re-write in python and generate the long g-code but doing it directly on the control g-code is more elegant.
