Hi Lloyd,

Welcome on to the site.

Sounds like you are off to a good start in terms of learning.

Mach3 or LinuxCNC are the controllers of choice with smaller new ones popping up now and then.

I am designing conversion kits for small milling machines for those without machines to be able to make mods to the castings. Since you have a bridgeport, then you will have no issue using the kit DCTTeacher on Youtube has designed and shared.

Keep us posted!
