Its always encouraging to learn of progress.From memory,there is at least one test example in the controller of the machine and I believe it is called "circle" I don't know if running it would help you along-but it might be safer to remove the cutter first.

The mention of cad programme is interesting-which is it?For some basic stuff there are several free cad programs that will generate .dxf files and you may have the inclination to try turning one onto a workable tool path.Can't help with that as I always used a cam program.If you intend to use a cam system it shouldn't be too hard to get a good outcome,just be aware that some are very expensive and you may have to pay even more for a suitable post processor.If you want to see what real indignation looks like you need to visit the Mastercam forum when somebody new asks for a free copy of a post processor.....

There are programs such a dxf2 cnc for turning an outline into G-code and you then have to add depths and tool radius offsets-Inkscape is getting more useful too even though it seldom works for me.Alternatively you might take a look at Heekscad or Freecad for toolpaths.Be aware that they take a bit of learning and Freecad is almost wonderful,but an absolute nightmare to get to grips with.For modest money compared to the industrial heavyweights,the various Vectric offerings are highly recommended.
