What grease do I use for bearings and ballscrew nuts? Didn't realise but some if mine are running dry at the moment!

Basically it's not that important for a light-duty machine. I just clean the ballscrews every so often with a rag damped with a bit of gearbox oil (75W-90). Rails too.

Thanks guys. Motor oil works a treat.
Motor oil might be a bit to heavy, plus the other thing you will need to keep an eye on is the swarf/dust sticking to the oil/grease on the screws which won't do the bearings a lot of good.
I'm using 10w/40 which is pretty light when you just coating the rails and screws. I agree with the sticky problem though! My Y and Z are well out the way but the X needs regularly cleaning. I use wd40 for that and works fine although tedious.
WD40 would probably work fine for lubricating it as well, not sure if it would be possible to fit some sort of bellows over the ballscrews to help keep dirt & dust levels down. Sure there must be something available off the shelf that would do the job.
Loving the speed and ease of the CNC. Got done in a week what would normally take a couple of months!
Now I just need a CNC spraying machine hmmm...
FLIPPING HECK!!!!! Where are those speakers supposed to go. Not sure I could even fit them through the front door. Look gorgeous mind.
