Advice please on 100cmx60cm CNC router

[JAZZCNC]

Thank you for your reply you have cleared up a few of the questions I have.
I have ordered the motors drivers will have till next month to buy more bits.

I strongly advise you to hold off buying anything untill you know exactly what your buying and why.! . . . Rushing to buy is THE single biggest mistake new builders make and perfect way to turn low budget into wasted budget.

What have you ordered.?

1.which controller do you recommend I would like one that's able to run on windows or a MacBook Pro. I believe ethernet is the most stable way to run but I am not sure.

Yes Ethernet is the way to go, avoid USB. The controller I'd use is a UC300ETH but this requires a good breakout board to get the best from it which adds to the cost. However the AXBB-E is a good choice if you don't need lots of I/O as it's got a built in breakout board in a nice neat little package.
I'd run both these from UCCNC rather than Mach3 but both will happily work with either.

2. Can you point me in the right direction to a circuit diagram for the power supply.
I will start a build log once I start
