Anyone ever experimented with carbon fiber rods instead of precision ground rods? I’m thinking an arrow should be cheap enough and readily available…
Yes I did. It made for a very light x axis, but the bearings wore grooves in them eventually.
I’d also imagine they’d be stiff in one direction and wobbly in the other.
My printer uses tent rods. That I bought in garage sale for 3$.
I used ceramic coated aluminum rods from pbc linear. Light. Stiff. Hard surface. I would recommend them. They do cost more… But they are easy to cut.
