I have a MT Series 36" by 36" router. I'm cutting small radi dimensioned at 1/32" out of .017" thick ceramic material. I'm cutting with a 1/16" carbide TiCN coated cutter. RPM=30k feed=5ipm. I'm using Enroute 4 to create the g code

i have to make internal and external radi. The internal ones look fine (as expected from cutter dia) but the exterior ones look like hexagons kind of (basically there are distinct straight lines). I've looked at my dxf i imported, looks fine. I look at the g code and it has a g03 to run the path. The job consul looks like it's creating a radius. Anyone have an idea why the external radi don't looks good?

Thanks in advance!

Sounds like your dxf arcs are being converted to segments. I don't have any cnc experience but I'm familiar with the phenomenon. Here's a thread I found that may give you some clues about fixing the problem:
