I am building a C-Beam Machine, what is the best software? I read that the smoothieboard is the best driverboard + has 4th axis support. Basically I would rather save a little cash and by the best set up then be frugal. So what is the absolute best board + driver option for my CNC router? I want the ability to add 4th (5th axis?) support and a usb hand jog. thoughts?? Thanks!
