It was actually an initial trial file to help set up my cnc router and get me familiarised with the whole process, and it was basically a superimposition of a PCB diagram that I want to engrave that goes behind a fascia panel with the engraved lettering. The later one is with the text included because my first attempts with another program would crash when the lettering was added. After I started using Qcad I could reinstate the lettering
I was asked to start with the CB file and then in the lower left pane click Machining, and go to the Arc Center Mode and select default, I need to do that tonight after work to see if that helps.
Cheers for all the assistance guys
