Calling all PCB CNC Milling Experts

[Qiaozhi]

Have you tried the clearing feature, to remove excess copper?

No - I haven't tried that.
The last PCB I routed on the CNC machine was 6" x 4.5" double-sided. Unfortunately the accuracy is just not good enough to do double-sided, and eventually I gave up removing all the shorts, and fixing broken tracks, and simply ordered some boards from China. Yes, it did cost more money, but the aggravation and frustration levels were much lower.

Thanks for advice, I'll try it.

Actually this cnc has .plt input like plotter. I am using enroute, which is able to work with .dxf.
I worked as fixer on mainly woodmilling CNC, but I have never met easy way to draw pcb and export it as .dxf.
