Hello everyone!

I'm new to the forum. I want to build, as you can read in the title, a 4 axis CNC router with tangential knife for rubber sheets cutting. Do you have any suggestions on which CAM software should I use to get the g-code in x,y,z and c axis? I also want to ask you which controller to use (e.g. Arduino, Raspberry pi, etc ..... and with which firmware)? What about mach3? Which breakout board is the most suitable for my project to work with mach3?

My last experince in CNC was the X-Carve project. I used an Aruino Uno with grbl v0.9 flashed and I got the g-code by HSM Express plugin in Solidworks.

Thank you very much!

P.S. I'm looking for the cheapest way! I also don't want to use a drag knife like this!
