I wonder WHY all the time.? . . . Often wonder WTF your on about and WHY you say the Shite you do.!! . . . . . Go back to the Stone age because your just confusing new users with BUM info that isn't relative to todays modern components.!! . . . . . Sorry to be so harsh but your going to cost somebody lot of wasted time and possibly money with such Rubbish.

Now that's the last I'm saying so OP can get back on track.

Edward:

You won't get near taxing those drives with Mill this size so don't worry about Over current etc. Just fit and enjoy.!

Regards Earthing then just use Star ground and shielded cable and you won't have any troubles. Size wise then 1mm is fine for motors and limits etc so just buy one size as it's easier and often cheaper as Some suppliers have minimum qty. 4-Core will do both
