Used 'Carbide Create' to make a simple 'schematic' for machining a PCB for a G3UUH style Crystal Oscillator/Crystal Checker.

The end result is quite pleasing (click the images to go supersized)

    

Seems to be working OK

CNC machining 'pads' on a CNC3018

I needed a circuit board for a TVI filter to stop 2 metre interference, like this (I'm going for the 144 and 432 MHz layout)

I used 'Carbide Create' to 'draw' what I required
(Click the images to go supersized)

Then, added Toolpaths to machine outside of the darawing/pads

Set the cutter, depth, speeds/feedrate etc and save the GCode.

Load the gerber into 'Candle' and probe the PCB for a heightmap.

Set it off with a 1mm end mill and the board was done cutting in 45 seconds!

Quite please with the result - hope it works when finished assembling!

Fully assembled and tested, over 83db of attenuation at 145MHz and 45db at 433MHz
