problems with post processor to WinCNC plasma program

I'm using a new CNC plasma table that has "WinCNC" plasma program installed. Sheetcam seems unable, with current default settings, to convert to
GCode any polylines/paths other than prefect squares, circles, rectangles and triangles. It seems to convert only the first line section, than omits the rest of the shape. Looking for any settings that can help these programs work together.

Any help greatly appreciated as I've used sheetcam for many years and don't want to learn a new program!

G-code can specify arcs in several flavours. Most SheetCam posts specify the arc center as an inctremental distance from the beginning of the arc. It could be that your WinCNC controller is set up to use arcs with asolute arc ecntres. In that case it would get very upset with any SheetCam generated arcs.

Have a look through the WinCNC settings to see if there is an option to change the arc mode.
