Hi Mesp,
Some CAD/CAM software's create arcs in Incremental Mode whilst other create arcs in Absolute mode ( you would need to Google it but the difference is basically the positioning of the centre of the arc ).
The IJ Mode setting within Mach3 is Modal so to be sure of the correct outcome all Gcode files containing arcs should specify the Mode (G90.1 / G91.1) as appropriate. This way you can run Gcode that has been created with any CAD/CAM software without encountering the problem you had discovered. Look at the Gcode of the smiley, it contains G91.1 so I knew it would run OK on your setup.
Tweakie.
