yeah, what he did with that thing is some very basic cnc opperations, G1 linear interpolation, G2/3 would make the curves I bet that thing only uses those codes and G0(Rapids) lets just say theres Gs up over 100
Heres some cnc stuff of mine:

Hi Jfettig,
It is quite impressive to see your converted mini mill in action. I am considering to build a low cost CNC milling machine using the low cost Grizzly or HF mini mill. From the photo, it appears your mill is one of those models. I wonder if you can share your construction knowledge with me? Just a few questions to ask:
- What is the torque of the stepper motors used in your machine? Would 140 Oz-Inch is enough?
- I am curious how you installed a ball screw to control the Z axis? These low cost milling machines use a rack and pinion drive mechanism which can't be converted to CNC.
Thanks,
Tommy
