elliott omnimill convert to cnc ?

Evening folks, im thinking of converting my manual mill to cnc due to the fact i have limited space in the garage and therefore cant fit anything bigger inside. ive read up and people seem to be using nema 34 motors, i know i will need ballscrews to install instead of the leadscrews i have.
so do people use mach3 with a bridgeport or are people using centroid acorn?
any help and guidance is greatly accepted.
thanks
