Need help building a cnc-cutter

[Boyan Silyavski]

Then you need something similar to drag knife, rotating blade as you say. It must be offset from the shank . Aspire 4 is the answer. It can generate drag knife tool paths .
This is done without motorized knife. its very easy to modify the tool path in any program, once you get the grasp of it.

By the way i am exactly now developing a drag knife, which is cheaper and i would say better, meaning more functional than the original one. It seems i have to think also of rotary attachment. Just tomorrow would be going to friends house to do some tests. The normal drag knife with utility blade will cut it, though holding down the material will be a problem. But not necessaryly, cause this will be much cheaper than round blades, if managed to achieve. Will report my findings, though glass fiber cloth, i dont have carbon fibre cloth.n
