Sturdy and Fast all Steel CNC , my first build

[Boyan Silyavski]

Hi,

the element A is a benchtop cnc 400x1000x200. The element B is not a table. It is another CNC, 1000x1500x200. It is the same, just scale the gantry.

So A is strong enough even if you put it on a simple table/strong enough/ . There will be no compromise of stiffness. Same with B.

In other words just follow B design if you like it. It would weight 130kg if following the design. Look at this thread also: http://www.mycncuk.com/forums/router...ddy-cnc-2.html to see it in real life

Silyavski i know that element b is not only a table.
I just use it as an example of table in order to give you understand what i mean
So you tell me that if i make a benchtop cnc 1000X1500 and bolt it on a table ( whatever strong table that can handle such weight ) i wont have any problems right?

Ok, I get it. If you use the same design and make a simple rectangular frame with the legs and diagonals on the legs, it would be rigid enough. If you use profile smaller than 80x80 you should use other design.
