Early-mid January is coming right up - I'd say the main thing you're missing is time. It's hard to say whether those motors will work or not, without having some specs on them and knowing what you're using for a power supply, Do you have a plan for this machine? What are you going to build it out of - aluminum extrusions? What are you planning to use for slides? Is this going to have a spindle of some sort? Are you going to use a breakout board? I hope you don't think you can run all those motors off that one driver. A picture showing how this proposed machine will be constructed and run would help us point out anything else that's missing.
