/diy/ - Do It Yourself

Thoughts on making a "table cnc" style very large printer?
I'm thinking of something like 1000x300x100 print area.
Replace the linear rails in pic related with aluminum extrusions and bolt everything onto a 5mm thick steel plate, this steel plate also works as the print surface.
It wouldn't have an exceptional acceleration due to it being huge and there being quite a lot of weight swinging around but throw a volcano hotend on there and the print speed ought to be pretty ok.
And as for bed leveling i'm thinking of using some sensor, mechanical or induction, on the hotend and then doing surface mapping to account for surface imperfections of the print surface.
I'm not quite sure as of yet which axis ought to be the long one, currently i'm thinking of making the axis in pic related that goes from right to left but i'm not quite sure.
