OK my cnc machine is well on it's way
I do have a question
I am using two ball screws for my x-axis and two motors
so my question is this
will I need two drivers for this and then if so where can I get a 5-axis system kit from under two hundred & seventy pounds?
like this but 5-axis
is it cheaper to buy the breakout board and drivers and make it my self
will I need two power supplies and break out boards?
what cables do I need?
this is getting confusing as I don't do electronics :confused::confused:

Definately two drivers with two motors. It's theoretically possible to do it with one ... but don't go there!
Those drivers are not very good at all - only 27 volts. You should get at least 50V, or 75V. That will be more like £200 for the drivers and something for the breakout board ... there's a cheap 5-axis one on eBay.
One breakout board will suffice, unless you run out of inputs later on. You just need as many power supplies as required to get sufficient power to the motors. I used a 500VA, 75V (when rectified) transformer for 4 motors ... it's ok on 5 too.
CY, 4-core cable 1.5mm^2.
Don't worry about the electronics, I'm sure I/we can assist...
ok Jonathan where do i order the drivers from

PM754 from Zapp is good - that's where I got them, but now there's cheaper available on eBay:
(those are not necessarily the cheapest, so do have a look yourself)
Transformer: Farnell good, eBay better if you're lucky...
I've got some capacitors / bride rectifiers so if you do get a transformer I can sort the rest of the bits.

I think I'm going to buy this set up as it has two extra drivers (spare or extra axis if needed)
but still unsure if it's the right think to buy
it is the same, I've ordered steppers from Ebay and asked if i could have something from Zapp as well but it was out of stock!
Get some pics up mate!! I wanna see a proper build log to base mine on! :P
Optoisolated breakout board with drivers that are already isolated can cause problems if you don't wire it right. Don't worry about it though, I'm sure it'll be fine.
