I am looking at upgrading the pc to handle the tool pathing better and quicker . I currently have a i5 3.4 ghz 8gb 64bit windows 7 with no video card , it is way too slow if I make the tolerance in madcam at 0.001mm .

I think part of the problem is the step over sizes I use to get the finish needed .... usually in the range of 0.02mm step over with a 0.1mm cutter and up to 3 million lines of code

any suggestions?

thanks
