Being new to GCode, I need some help understanding of usage of the G2 and G3 commands.
How is G2 and G3 used with I, J, and R in controlling the size of arc generated? and... What's a good way to have my X-Y table generate a 0.500 R circle once, and one that goes infinitly in a circle?
FYI - My application of GCode will be for controlling an X-Y table inside an electron beam machine with a fixed gun. I also prefer to use incremental movements and presently begin my circles now from a 9:00 starting position.
Any help would be much appreciated.
