What would be the best way to drill holes on the circular face of a cylinder. The holes are pretty random and don't have any specific pattern as such.
The mill that I have is an el cheapo 5axis chinese mill that I bought on aliexpress.
The cylinder will be oriented parallel to the bed and rotate around the A axis.

My question is how do I go about doing the G code, do I have to handcode it? Or is there an automated way to go about it. (I guesss they call it CAM)
I have Mach3 driving the mill.
