Hello there,
I've built a couple router machines, and now I'm about to move on to a foam cutter. I have what is probably a 'stupid' question, but that's not unusual for me...

searching on line I've noticed that some machines produce 'tapered' cuts by having all axes independent. The question is: how do you deal with the length of the cutting wire? Once it's on an angle, it needs to either stretch, or be fed somehow?

Thanks!
