>FDM surface finish
the surface finish with my method is as good as with injection molded plastic.
>Just buy a 1mm thick sheet of PTFE and cut it up into rectangles
Good idea, will consider it if PLA proves to not be good enough
>anodized aluminium is a rougher surface than a linear rod or a rail
yeah, so i've noticed, i wonder if sanding with a 1000 grit wet paper or something would be worth it
>especially with a large surface area
how does surface area affect friction in this case?
>You will also need a way to preload the bearing surfaces
why preload? isn't it enough that i adjust pad thickness until it slides smoothly enough but without much wobble?
>backlash
what do you mean by backlash in this context?
