Well, I decided to buy a cnc router for myself for Christmas. I started out with a 3040t Chinese machine. It was low cost and something to learn on. Even though I am a Tool and die maker I haven't had any cnc experience. These things come with no instructions, and I am trying to figure it out with very bad results. I am attempting to use Inkscape for drawing and Mach3 for controlling. I've been on You Tube for hours, and have learned some. One of the problems is that when I import a DXF file to the control software I can't seem to get it to cut the same size as the image I downloaded. If there is a patient person out there that could help a complete nubie I would sure like some help.
