Great info, cheers!

So it certainly sounds like a better option to tweak that layout somewhat, guess I need to have a think of what I want out of the set up. worryingly I hadn't even thought about an E-stop system yet!! I would at a minimum hope to have an e stop to kill the motors and spindle, whilst keeping the system powered still.

We had a machine at work that had floor mounted E-stops and god knows why but they literally killed everything, PC included, so you lost all your datums and tool offsets. Most annoying when you accidentally kicked them!! I don't want that...
