Examples of code to run the machine
Warning! be sure you change the font in Notepad so that
it displays the slashed zero. O, the character is used to define a
subroutine in this example O23 and O22. This ate my lunch the first time.
This is used to round a 90" piece using side cutting with a up cut end mill.
Starting at X0 tool moves in .02" on Y axis and then moves 90" on X axis.
A axis rotates 2 degrees and tool returns to X0. This repeats till A has
rotated 360 degrees and then the cycle repeats. This gave me a nice
finish on the fir that I was turning. I will have to work with different
cutters to find out which will give me the best cuts.

This is a rope twist of 4 starts and 4 revolutions in 16". This was
before I learned subroutines.
