I've been having some problems converting DXF files to be cut in Mach. I'm using SheetCAM v4.0.0 and Mach3 v1.84.001.
I've attached a sample DXF file, and the resulting g-code, and the images show the path in SheetCAM, and Mach's Toolpath display.
For some reason, at line N0230 the G03 move causes Mach to take a large circular arc, but if I run the file through MicroTech's CncSimulator the simulated tool appears to behave as expected.
The source of the DXF is a little strange - it's come from 3D Studio Max, and was exploded twice in ProgeCAD before being exported out as an AutoCAD v2000 ASCII DXF file.
More complex files (with curved shapes) suffer from this problem very badly.
So... is the problem due to something odd in the DXF, SheetCAM doing something strange, or Mach not interpreting the g-code correctly?
Bit stumped on this one, so any help would be greatly appreciated.
