Thanx for having me 😅
For now i guess the ballscrews are going to be typical C7 rolled Chinese.
The 1st question i have at this point.
what would give best results.
A) Slave the 1600mm balscrew steppers or;
(i am not up to speed on how this actually works but i do get the general idea)
B) Connect the ballscrews through a belt and a single stepper.
And is then still a nema 23 3nm ?
Total length of this belt would be +/- 2300mm.

I can tell you thru much experience that Twin screws are much more reliable if connected with timing belt. They remove any chance of screws becoming out of sync.
The only down side is they require larger motor and drive. If the machine is wide then they can also get a little unweildy. In this case Twin motors can work best. At the size you plan they will work great.
Using screws joined with belts my prefered setup over slaved motors.Last edited by JAZZCNC; 29-08-2016 at 11:56 PM.
