Since I also have a deep interest in this topic but, like others, no programming ability I have hesitated to throw in my two-pennorth but, like Andy, I am also interested in being able to use the rotary axis for covering a disk in concentric patterns which will involve many rotations of the 'C' axis. I don't have any constraints on my time and so winding back to '0' after each revolution may be feasible but would increase the time taken by a job by maybe 50%. Continuous rotation would be much better from a continuity point of view but it occurs to me that, while this would get rid of backlash errors, there may still be some cumulative errors if the script calculates the rotation as it goes. (maybe I'm wrong here - I don't know...) I also need to use my rotary axis for cutting very accurate gears - tiny ones for use in watches. For this I would very much prefer to continue using degrees as the measure of rotation. I have used a program called Artcam for making jewellery in which a design to be engraved around a ring has to be laid out as a linear strip on the screen and getting the two ends to meet up exactly on the ring can be a nightmare!! I haven't tried it yet but wouldn't
