I wouldn't be worried about the steppers but the drives in your spec you have said that you are using these M542H If I am not mistaken the max voltage they will handle is 50V so 48V would be too high for them. AM882 drives would be a better choice running at about 68-70 V.

Ok then if you have not bought the motors either then try and find 8 wire so they can be connected in parallel and get the lowest inductance motors you can find these are proved and tested by many over here :- http://cnc4you.co.uk/resources/Stepp...1B%203.1Nm.pdf.
Good luck with the build...Clive

You can run both X axis screws with one motor and belt connecting them,it's common practice with the guys on the forum.
Good luck

You can get custom belts but they are more expensive, but you have a lot of leeway length wise as you will have adjustment on the motor and your tension/routing belt layout. there was a post on the forum a while ago showing a belt routing setup to address this issue.
