Thanks Mik, I'll give it a shot.

Thanks Chris, as far as I can tell there doesn't seem to be anything wrong with those DXF files, my guess is that the laser cutter software doesn't like to get lines that are too short.

Thanks Michael. I'll try the polyline suggestion and see how it works.

Chris, can you mention the name and model of the laser system you are using?

It is possible the bundled software has the ability to generate tangent arcs from the splines within some user defined tolerance. In that case saving as a spline would be better than saving as a polyline.

The setting for the conversion may not be entirely obvious. I've worked for a few CNC manufacturers, including lasers, and sometime the software included with the machine has the functionality spread over several applications rather than being conveniently integrated.

Hi Chris,

I remember that I had similar problem as well. Some of small circles, especilly circles with diameter less than material thickness, weren't cut correctly. Problem was solved by changing laser parametres directly in laser cutting maschine software. Producer of maschine provided to programmer "hidden" settings, so now laser beam can be slowed down before the end of finishing whole circle and therefore now it can be cut small circles into thicker materials -even 2,5 mm diameter into 4 mm Al metal plate, without changing of DXF export setting.

Hope this helps.

Mik

Hello,

It sounds like you need a DXF file optimization program. I haven't used them but you may want to demo something like DXF CNC Graphic Optimizer or DXFTool For CorelDRAW.
