The price is about the same for two motors or one as you only need one drive if using one motor.

Not sure what you mean. You will need two screws either way
Clive.. i understood the single nema34 setup has a disadvantage ... it is bigger in diameter and has to run about 2.4 meter of belt between the screws.

The inertia of a nema 34 is higher than a slaved nema 23 setup, right?


A single long belt nema34 on 2 ballscrews vs a slaved dual nema23 software controlled solution.

Hmm sounds like i just made my choice aaaargghhh... no.

Is a stepper +/- 6nm nema34 still an option or is the twin ballscrew 70+ kg gantry asking for a servo solution.

BTW i dont want to start a discussion here on single 34 vs slaved 23.
