I am looking for a way to digitize 2.5 d parts using a mach 3 controlled machine. I want to be able to set it to follow the outline and than export as a dxf. I know their is a lot of options out their and am a bit lost as to what is best for me. We used to use a profile cutter which had a "magic eye" which traced a dwg to get its motion commands. That is what i'm after, except the machine would follow the part and record the path of motion and export the dxf. Is their a probe to do this or perhaps a usb camera and software to suit. Can anyone point me in the right direction?
