MASSIVE 2.5M x 4M BED - GANTRY DESIGN HELP NEEDED!!

We could probably get this down to 500mm

We could probably get this down to 500mm

Now next is my common sense, later you could prove it in the calculator.

-Then you will need a gantry vertically wide so that 500mm spacing between bearings is achieved.

-2x 150x150x4mm /18kg/m/ separated 200mm and connected every 500mm with braces from 100x100x4mm that all form a leather like structure. Similar to my gantry. Could be reinforced with bolted later steel plate of needed in some direction, though i doubt that you will need for wood.

or simply weld together 2x 200x200x4 or 5mm, though careful engineering here is very important


- You must decide at this point how you will move Z left right, RP or rotating ball nut, how you will move the gantry on long axis, all that before continuing with the gantry design, cause you will need space in between for the rotating nut to pass and so on.

But say 600mm to be on the safe side

Well, I can get my hands on a 50mm ball screw and nut from the same machine the rails came off but the components I will need For it I feel will probably cost more in the long run than RP. So I am tending towards RP at the moment.
