Thanks Dougal, I got your files and did some investigation - and thank you for your patience.
I tracked the problem down to the WorkPlane setting in the Engraving machine operation. This was set to Workplane=Unknown.
The default WorkPlane parameter is the XY plane and controls which planes arcs are defined in and whether to use IJ, IK or JK arc parameters. Unkown confused the gcode output resulting in 0 I & J parameters.
To be honest, I am not sure why I put the Unknown option in the list of WorkPlane options and I have made a note to take it out of the current development version.
I apologise if this has caused confusion. Setting this property back to the XY plane caused the I J arc parameters to come out correctly.
The other file you sent seemed OK, apart from the use of ArcCenterMode=Absolute. I changed this to Incremental and was able to simulate both your files in CutViewer without any problems.
I hope this helps.
