Re: Flashcut questions

As I recall the program doesn't support cutter compensation. You would have
to either draw the part with the diameter of the cutter to be used in mind
or you can create offsets from the main drawing and then convert the dxf
files to g code.
The z axis is set in a setup file because if you wanted mulitple passes to
achieve the depth that you wanted you would be stuck if it imported the z
depths or you would have to edit them.
