This was my first attempt at milling my own single sided circuit board on my 6040 CNC router. Along the way I had some issues with the pcb blanks bowing, but I ended up with a functional LPT to USB adapter for Estlcam.

Because the pcbs blanks where bowed, the first couple attempts failed.
First attempt: Some of the clearance routings were too shallow.
By screwing the blank down, the bow was eliminated and a constant cutting depth led to more reliable isolation routing.
Next attempt: Screwing the blank down.
Successful attempt: Routed pcb.
The pcb fitted in the cabinet.
