    I am looking at building a Rockcliff machine. Having modeled it from the plans I can understand the mechanics of it and will learn its weaknesses soon enough.

    what components are required to make it move?
    PC with design software and then postprocessor (mach 3).
    A controller is then connected to parallel port. Is the controller also the power supply for the motors?

    I would like to buy what's required even before I start the build so that I can setup the motors and get them spinning asap.

    Having purchased the MDF, I will hopefully start a build log soon.

    And does the controller also manage the limit switches too?

    Skittles, have have you looked into this yet?

    You will need three stepper motors, three drivers, power supply powerful enough for three axis and a breakout board.
    Either the FL57STH76-2808 or the M60STH88 motor would work, with the M60 motor offering a lot more power.
    These motors work very well with the MSD542, and we suggest two PS407 power supplies.
    Have a look on our webshop, we should have everything you need?

    I appreciate your help but am always a little wary of salemans advice. Lee what did you use?
    I used 3 of the FL57STH76-2808 motors, 3 of the MSD542, i only used 1 PSU however.

    You can take Gary's (Zapp) advice to the bank Mr Horse.:D

    I bought my motors, drivers and PSU's from Zapp (+ballscrews etc)and they are a first rate outfit IMO. I went for driver kit 1 and it has been faultless. Your router is going to be quite a bit larger than the plans with consequent increases in weight to move around so I'd go for the more powerful 60 motor and 2 PSU's.

    You are also intimating this will only be a stepping stone to a better machine. The more powerful moteor will pay you back then as you will maybe find your next machine will be even bigger/heavier. I skipped the stepping stone bit and went for the full monty :)
