    Default CNC mill electronics help

    I have a taig CR ready mill (2 of them actually)
    I have a setup that is ready to bolt onto one of them but the other I have nothing. Looking for recommendations on something (inexpensive) just to get it working and do light cuts on aluminum, wood etc so I can sell it. So I don't want to spend $300+ on it just to sell it.
    Would need the motors and all electronics and something I can run mach3 demo on and have it be plugged in via USB.

    Something less than $200(MAX) the cheaper the better.

    Also I have never used mach3 so if anyone has a setup file they can share that would help me out tremendously. My setup going on the other mill is all flashcut plug n plug play.

    Don't bother putting a cheap and crappy control system on it; sell it CNC-ready and let someone else make that mistake if they must.

    I still haven't figured out the difference between a 'good' controller and a 'not so good' one.
    So I can get a cheap breakout board for $60 and drivers for $15each. Say $105. It's good for 3 or 4 amps. What benefit would a gecko that is rated for the same amperage have at 2.5x the price? They both would run mach3.
    Would I get any noticeable difference (aside from warranty and support)?

    Also while I'm thinking about it.
    So whats the difference between using say a 480oz motor at 2amps and a 270oz motor at 4amps. Which is more important and why?
    I always thought having a larger motor was better but the amperage draw has me a little perplexed.




    looking at this board

    maybe these drivers? Not sure what to look for in specs exactly

    And while I'm at it. Is there any real difference between these PSU and one I can pull out of a desktop pc?

    I have a gecko g540 and I've built 3-4 machines using Automation Technologies KL kits and also cheap $10 china 5 axis breakout boards and $10 TB6600 drivers. Actually, they have all worked fine and I haven't had any particular issues or disappointments with any of it, whereas I have had issues with the "better" breakout boards from CNC4PC. Maybe just luck, but when you can buy a extra backup BoB and a couple extra backup drivers and have everything you need other than the power supply for about $70, it works for many projects. No frills, but they work.

    Best advice I have seen here in a long time.
