I've got my Series II, Boss 6 finally up and running somewhat reliably in my garage now... so I have a question on the syntax for using polar coordinates. The programming documentation I've acquired is for an earlier control and doesn't cover this feature. What I am attempting to understand is the use of G03 circular interpolation while providing (A)ngle and (R)adius parameters. I am also confused with I and J being specified as absolute coordinates for the arc's center. Can a Z axis move be incorporated with a G03 move? Could anyone shed some light on this for me... it would be greatly appreciated!
