I agree with all of the above. We take templates of counter tops, boat decks, shower floors, etc. We can then make them out of Corian and engrave them with designs. To make it smooth again we fill the design with a graphite impregnated epoxy and sand it down. If there was some type of way to line trace and get a vector out of the machine it would save us a LOT of time.
I have tried a 'stitching' program that puts pictures together. It works ok. It would be much nicer if we could pin the template to the table, show the machine a line to follow, give it a direction to follow, and then hit probe (scan). This could be a differeniator for Mach 4.
I love the flexibility of Mach 4 and if any program can do it then it is probably a Mach 4 based one.
