I'm having trouble with Mach3 (version 2.0) during the loading of the G code file and Mach3 does a simulated run to test the progrom.  Basically it complains with the following status message: "Radius to end of arc differs from radius to start on line number 1940".  Does this message from Mach3 seem legitimate based on the G code snippet below?  Or is possibly the problem with my CAM software (RhinoCam with post for Mach 2) generating invalid G code?

Here is the snippet that Mach3 is complaining about:
N1920 G01 X0.9810 Y1.5748
N1930 G01 Y2.6077
N1940 G02 X-0.9817 Y2.6085 I0.0000 J3.5151
N1950 G01 X-0.9829 Y1.5239

I'm very stuck right now-- I've never had this problem before with RhinoCam and Mach3. Thanks in advance for any advice you can provide me.

try changing the IJ Mode on the General Config page in Mach.
