I want to machine wood mostly, but have the option for occasional aluminium/brass machining. May require adding stiffeners to the top of the Y axis gantry, but I figure that’s for a next step. Some similar machines have 2510 or even 2525 ballscrews, but that seems like overkill. Or is it just enough kill?
If you were using steppers, 2010 on long, 1610 on the other horizontal, and 1605 on Z would be reasonable, but you're wanting to use servos so it might change things - depends on what speeds you want out of the machine and what gearing ratios you want to use.

This seems like a good option on paper, albeit one requiring a pretty hefty power supply.
Generally advice is try to use Ethernet where possible - USB is somewhat notorious. A few people around here build their PSUs, so might be worth reading up on it.

There are some interesting options on Ali (like BST automation) - that is until you add shipping and duties, at which point I figure I’ll just buy local for the added peace of mind. But if anyone has good tips, I’m all ears.
Have you tried emailing BST directly for a quote inc shipping? Duty to the UK wasn't a big issue when I ordered mine. Mention the forum for what its worth!
