Mach 3 / CS Labs Smoothing

I'm looking at a screenshot of the General settings page, I dont see it. Any idea where it is?

https://www.machsupport.com/wp-conte...all_Config.pdf - page 5-35 is the General Settings Page.

Have a look at 5.6.6.2, I/J Mode: You can set the interpretation to be placed on I & J in arc moves. This is provided for compatibility
with different CAM post-processors and to emulate other machine controllers. In Inc IJ
mode, I and J (the center point) are interpreted as relative to the starting point of a center format arc.
This is compatible with NIST EMC. In Absolute IJ mode, I and J are the coordinates of the center in
the current coordinate system (i.e. after application of work, tool and G92 offsets). If circles always
fail to display or to cut properly (especially obvious by them being too big if they are far from the origin),
then the IJ mode is not compatible with your part program. An error in this setting is the most
frequent cause of questions from users when trying to cut circles.

Thanks. Ive messed with this before. Normally when its wrong, it doesnt cut the right tool path at all. I dont think that's the issue here.
