Cut my first gear on CNC

[RC-Monster Mike]

Mach3 has a gear cutting wizard, Rene - its almost too easy once you have the setup figured out. The code is dead simple, too - rotate the A axis by the 360 degrees/tooth count(a 36t gear gets rotated 10 degrees for each cut) and cut to depth. Rinse, repeat. I actually do it on a 3 axis machine(position and lock the Z, then take the Z motor cable and connect it to the A axis motor).
