Hi Kirk, Looks like you have been having fun in gcode. One thing you might want to consider for an encoder wheel is to make the cutouts the same size as the solid areas to get as close to a 50% duty cycle on the detector(s) as possible. You didnt say if you were just using the wheel for a pulse generator or a 2 channel encoder. You might also consider adding another hole for an index detector if you need that. Along a similar line, you can check out a lathe spindle encoder I built a while back. The gcode program can be adjusted to make an encoder of any number of pulses. If you are using slot source/detectors, you have to make sure the holes in the disk can be reached.
cheers... post a picture when you get it made!
