I finally have decided on which machine I am going to purchase (Fineline 2x4 8020 kit), and THOUGHT I knew about the electronics, but the more I look into it the more confused I get. Is there some kind of primer on which Software, Plugin, Motion Controller. BOB, Drivers work well together? I don't want to cheap out and get components that limit me, but don't want to needlessly spend money on things that I am only using 10% of, or spend an arm and a leg on a pre-assembled kit if I can piece it together for cheaper. I have seen BOBs on ebay for $5, and chips alone that are $150 that need to go into a $100 board.

Does anyone have any input on a decent setup that won't break the bank? I would need 4 axis, the potential for a rotational 5th down the road would be great, I would also like to be able to have limit switches, homing switches and a Z axis tool height alignment switch.

Thanks!
