Rigidity for Shapeoko

Post by sectorix » Thu Aug 14, 2014 11:01 pm

Hi,

Has anyone ever change the GT belts on a shapeoko 2 with M8 bolts like the Z axis upgrade?
Im wondering if that will make it way more accurate and rigid.

I don't think it's rigid enough in it's stock form to really take advantage of a screw-driven X and Y. You'd gain is the ability to push harder into material, but you aren't adding rigidity, so what will happen is you'll just cause more deflection where you already get some, for example the gantry rail twisting around X.

It may add more accuracy and virtually eliminate the need for calibration, but that's it. It's already pretty darn accurate. Certainly enough for what I want to do with it, which does not involve honing precision bearing races.

I agree: the belts are quite solid compared to other parts of the machine, so the benefit will be minimal.
