UCCNC will only work if you have a Motion controller from CNC Drive. Their motion controllers will work both with Mach3 and UCCNC software using plugin for Mach3.

Mach3 and a Simple BOB will get you going providing you can find the Pins out's. However, if your running limits and speed control/direction along with ATC you may find you run out of I/O as the BOB as limited I/O. Personally I would fit an external motion controller anyway just for the reliabilty and to get away from the parallel port.
