Need Help!- cnc rail DIY, ideas?, any intersting project on cnc rails / Linear Slides?

[sadik007]

Hi all..
Just got the board and motors. Now, need to figure out how to make cnc rails.. Any ideas, have you seen any good projects. I am interested to make then, to be as cheap as possible..

I was thinking to get kitchen cabinet rollers, they made very good once these days. I have seen few rollers over tube setup, anything simpler then that.. Would L profile steel work with rollers from top to bottom sliding work?? Or maybe, sliding/hanging door rails.

I am planing to make 1000 mm by 500mm machine, wood carving CNC machine.. It is bit big..

Has anyone considered using L profile steel with roles from both side holding it in place.. to me this sounds like simple enough setup.. Or even square steel with 3 roles holding position and bearing..

All comments welcome.. I am planing to do wood carving CNC..

Interested to hear your experience.

thanks

rectangle steel idea


For Sliding door setup.. was planing to use pull force between two opposite sides to ensure perfect slide.
