New build – input/comments appreciated

[ngundtoft]

I have stiffened up the X-axis ballscrew nut mounting by increasing material of bracket to 30mm, increasing cover plate to 10mm and inserting a 20mm triangular support.


I feel somewhat uncertain with respect to using a single motor and belt setup for the X-axis. I remember reading that the Nema 34 motor should normally be avoided because acceleration is much slower than the 23. So do the advantages (better alignment, single motor) make up for the drawbacks (lower acceleration, long complicated belt)?

Maybe a long belt could just go below the top cantilevers (and the bed) by using some extra idler pulleys?
