What should be the thickness of the aluminum profile?

[3DStyle]

Hello,

I'm about to start my R-CNC project. The aluminum profile I can get in my country is 100x20, the 100x18 is unavilable.
I can get the aluminum profile from 2 different stores; one have it with 1mm thickness, and the other one have 2mm thickness.
The 2mm thickness is more expensive, and I would like to know if this 1mm diffrence worth the extra money?

Thanks!

Hi !
I think it will be the same result if you buy 1 or 2mm thickness because it's the geometry of the machine that makes its rigid, not the material used

So today I bought all the necessary aluminum and steel profiles expect the 20x20 aluminum angle.
For what are exactly 2,5 meters 20x20mm aluminum angle? I can't find any information about them in the guide.

It's for the waste board (look at the picture of this remix to understand):

By the way, what should be the length of each one? In the parts list page it says 2.5 meters. How many peaces will I need and which length each one should be?

Hi !
The lenght you need is the lenght between each printed corner parts

Here in the uk we cannot get it as profiles but can get 100mm x 18mm as straight edges for concrete tampering so thats what i have done seems to work ok.
