WHAT DOES ALL THIS MEAN

I am not sure of the meanings of all these choices they are giving me. I need a control box for a 3 axis cutting table. i have 3 keling technology stepper motors model # KL23HM276-30-8A it has 0.9 degree
someone told me that is the steps per revolution. but then i see that it can be unipolar, bipolar (series), Bipolar (parallel) digital, analog? there are a lot of controllers out there and i have no idea what i need. i know the steppers are nema 23 stepper motors looking at all info i can find on them they should be 4.2A . Keling has multiple control boxes available some say thry are good for all nema 23 bipolar stepper motors, then it says good for 3 amps. my nema 23's say 4.2 amps ?????????? i am confused and would love to get past this point so i can get into some real trouble when trying to figure out how to run the machine and learn the software. funds are limited, but i need a control box that will last. Any suggestions?

I don't know if my post is being ignored being i am a NEWBIE or if this is supossed to be common knowledge among those who frequent this site. what ever it is i feel like a fool for posting now. I guess i was expecting someone to at least point me in the right direction as to where to find this info. i will figure it out eventually and i will add my findings to this post and maybe help other NEWBIES have a better understanding of the lingo and power requirements for a control system.
