It'll be on a bench with access from all sides, so if I do have to open it up it won't have to move anywhere. The only time I'd have to move the box is if I moved the machine, and that just isn't going to happen, I've designed my enclosure around a prime spot where I can vent it straight outdoors. That and there's not really anywhere else for it to go.

What about the wires, do they need matching at either end? Any tips/tricks for getting blank unmarked/uncoloured cables matched up?

The 2200 series are 2.2kw and 1500 series 1.5kw... 800 are 800w spindles. What a nightmare. The Chinese are on holiday as well aren't they?
