Been a bit busy with work and jobs around the house so have not got much more done yet. I have been looking at the costs of materials and may be a bit pricey to use aluminium t slot extrusion on the machine.
i am looking at aluminium box section 60x60x4 for the frame and 120x60x4 (2x L shape config) for the gantry. Is there much difference in strength / deflection using box compared to the t slot ext and how does it deal with resonance? What materials are generally used to dampen if it is needed?
