Gantry Aluminium thickness guidance

[MikeyC38]

Thanks mike - 1 question,

Your gantry sides are 20mm - these are the largest plate connecting the Y and X axis, where did you use the 15mm plate for?

Any did you use plate for the Z / X axis.

I have also used high grade extrusion, the bare weight of the aluminium along for me was 76 kg. I think the Y axis was 9 kg/m, and the X axis around 5-6.

Hi Nick

I used 15mm plate at either end of the long extrusions (x-axis) (see my build log photos for the bed construction). For the Z axis construction I used 20mm 5083 cast and machined toolplate. It has a very fine and accurate surface finish which is critical for the setup and accuracy of that axis.

I'm trying to CAD up another concept, but Fusion360 is down on my laptop !
