Carey, I think Don has the right fix. Use the G18 to set the correct plane for your arcs. At one time, I seem to recall a problem with other than G17 arcs, but I think that was fixed in CNCPro.

For the time being, if that does not work, Select your tool path & change-Break-Interpolate to create a series of short line segments that approximate the arcs. These can be established at as close of a resolution as you want. With look ahead they will still cut nearly as smoothly as an arc.
