Looking for a little feedback. I am new to G code programming, though not to Basic, Cobol and Fortran programming (years ago).
I wrote this program to drill cylindrical hairbrush handles. The brush has 12 rows of 14 holes, each row spiraling at 17 degrees and every other row offset by 1/2 space.
My concept is to drill 15 holes along the axis, take 1/2 step and rotate to next row to return to the end, rotate and repeat 5 times.
What code will have this repeat 5 times?
Have I neglected something to tell the program axis A it is rotational?
Any other comments?
