A 20mm screw instead will give you a max rpm of 1260 which bumps your possible rapids up to 12.6m/min, but will take slightly more power from your motors.

The Y axis gives you a max rpm of 1800, which is fine.
Could you make that calculation for a 2.2m long ballscrew? I only have 2010 available so far.
