very basic cad cam software

Charlie, I've attached the cb file, you need to set the depth of cut, spindle speed, feed rates, etc. The biggest tool that would do all of it was 3mm diameter so that's what I used.
Also you're drawing was way out in no-man's-land, it's best to make drawings around the X0, Y0 position.

Hi guys many thanks for all the help, I used auto cad to draw it as it was what I was most familiar with and I was struggling a little with drawing in cambam. I found the problem in auto cad it was some if the chamfers are not linking up for some reason but some are ( it's the ones that go from a circle to a straight line) I have generated what I think is the correct code so will try running it in some foam first and see what it does and allso compare it against what you have given me eddy ( many thanks for that much apresiated)

Use PEDIT in AutoCAD To join lines and arcs into a continuous closed polyline.

I just had it cutting and all looks good however I noticed that the 3mm holes I had it does not want to do with the 3mm cutter is that because you cant go straight down only? ( this is using my file)

many thanks

Try making the holes 3.1mm and rout them out. ( might even work with 3.01mm). G.

3mm works fine if using a drill mop
