Hello

[JoeHarris]

Personaly yes I prefer one motor using just the system you have drawn.
My machine is done this way and it completly eliminates some potential issue's that come with slaving motors together. I have used both methods and by far prefer this method.

Thanks Jazz, that's very helpful. Do you have any pictures of your machines that have used this method or could you point me in the direction of other builds so I can get a better understanding of how this will work in practice.

Jonathan - if you are still keeping an eye on this thread - I have seen on other threads that you have successfully developed a rotating ballnut system. I was wondering if fixed ball screws held in tension along my x axis would make sense here as it would eliminate whip? Do you sell your spinning ball nut mounts?! :) presumably the arrangement shown in the previous post could be used to drive two ball nuts mounted on the y axis gantry?

Does anyone have any pictures of a good twin x-axis (fixed) ball screw mill?
