MendelMax 1.5 scaling document

[EberleG]

Hi all, I'm planning a MendelMax 1.5 build and want to scale the bed to 300x300.  Looking around and there seems to be lots of reference to a scaling document, but all links to this are now dead (as is the original mendelmax website?).  Does anyone have this document so I can plan the extrusion lengths I'll need to use to accommodate the larger bed size?

Do you mean this here? It's actually pretty easy to scale if you don't mind your Z-height increasing a bit.

Go up in rod diameters too.  I built one for a 300x300 bed (increased extrusion lengths by 100mm), and I increased the Y and Z axis rods to 10mm.  If I were to do it again, I would increase X to 10mm, Z to 10mm, and Y to 12mm.

That's exactly what I was after, thanks!!

Thanks for the tips!  I was thinking of 10mm smooth rods, but now thinking 12 on the y-axis might be the go.

For my Y axis I have one of the linear rails from the now defunct trinitylabs, which I'm extremely happy with. You may want to take a look at the rail solutions rather than smooth rods...

Actually some of the supported rails that are used for Kossel printers would work really well on the Y axis, especially since they are far more precise.
