Alternative x-axis belt mount

Post by Kjetilei »

I made an alternative x-axis mount to improve the printable area:

This updated part, looks very nice :). Got a few questions.
- Did you mount it with only one screw to the frame?
- Why are the vertical flanges at the location of where the pulley should go?

One screw in the side and on in the top that also holds the washers and bearing. I used the longest screw you supplied and I believe it was a leftover from the conversion from B to C. The top screw could be shorter and only hold the bearing and washers since the rail and the bottom screw should keep the mount in place. But I had the parts laying around and thought it wouldn't hurt...

I'll try to take photos of the assembly later tonight.

The vertical flanges are built-in support for the printing. Four single width "walls" and one single width cylinder = enough support and less waste and clean-up :)

It seems actually pretty nice to take the long bolt to mount the pulley and also mount the part to the frame.

The support can alternatively be obtained by the raft plugin in the software. It automatically calculates the needed support material. See screenshot below

If you hate cleaning up support material, you can adjust the interface/support lines density ratio to a lower value. I normally use 0.25, but lower values should also be sufficient.

To tell you the truth: I didn't bother learning the raft settings (too much else to learn at the moment). This was the quick fix :)

PS: I'm currently disassembling the mount and will take photos shortly.

:) the 3d printing takes time to learn. It's not as easy as a paper printer, even those things can be difficult sometimes.
