Sorry for the double post.

I've cut some parts using LazyCam to generate Gcode and all went fine, but I'm now regularly getting these "zero radius arcline 564" errors after offseting in LCam.
There are many other lines with a zero radius...
Why is LazyCam generating this error when creating offsets, and how can I get away with it?

Thanks for your help, after all the time it took me to get there, this is rather depressing

PS : here is the Gcode file

I have noticed in the past that I have run up against the same problem.

Some where along the line, one of the programs used in drawing, or creating G-cod (Lazy-Cam), has rounded down a very small number, say ".0002" to ".000". What I did for a quick fix was to just make the zero radius the smallest number acceptable by my CNC program.

For me it wasn't a serious problem, but I would check to see the settings in all your programs, to make sure they all have a decimal place setting of 4 (".0000") to allow for small fractional numbers without rounding down.

Hope it helps a little

Bob,
Can you post the  DXF drawing?

Once I corrected the two or three lines by changing "0.0000" to "0.0001" everything looks good. Ready to run on your CNC.
