I just had a thought...

As of this current version, G2 and G3 commands (arcs) are not supported. This is OK for PCB's because commands are usually G1 (linear) but for whatever you have in mind, this may not work yet if your GCode file has any G2 or G3 commands. I do explain this in the website somewhere but I am worried that you may have missed it and it is worth re-mentioning here I think.

I think MadProfessor managed to get round this problem when he converted these G2's and G3's into lots of G1's using CamBam?

This may not be a problem for you but I just thought I'd mention it.

best,
