Mach 3 gives me an error saying that the end point of the rad/circle does not match the start point of the rad/circle.

For now I have been eliminating any rads/circular cuts, but this problem will need to be addressed.

I'm using Gibbscam 2009, with the posthaste....using a Fanuc 6M, Mori Vert. mill (Fairway).pM3 selected as the postprocess.

Is this my problem, or something to do with Mach 3....let me know if I should post this in Gibbscam forum.

That can happen if the precision of the post-processor is set too low. In other words it rounds off positions to the nearest 0.01mm or whatever and that can be to coarse for Mach3. See if you can set precision of the post-processor to 4 decimal places and see if that helps.

Another common problem with arcs are that IJ mode are set wrong but I don't think that's the problem in this case. It usually shows as large "crop-circles" instead of arcs in the toolpath. Anyway, to change the IJ mode go to Config->General Config. But again, I don't think that's the problem.

It could be the IJ mode. I'd check that first, as it only takes a second.

I do get large crop circles...I don't see the General Config under Config menu...I found the IJ mode from Incremental and Absolute under Config->State...switched it and I got no error and the toolpath drawing looks good...a run will be the true test but I think it worked..

Thanks to everyone!
