Adventures in 3D printing

Started on the first telescope part last night. Should be done around noon. 14.1” diameter by 6” tall.

Very good looking print, and NICE large working envelope on your machine #envious

Finished part was waiting for me when I got home from work. Guinness for scale!

Looks flawless, great job. What telescope are you making, btw? I know nothing about astronomy or astrophotography, but looks like it will be a large scale assembly.

It is a custom made 13.1” f4.4 mirror from Zambuto. It is one of 5 telescopes that I have at the moment. It is about a midsize mirror.

I am considering making a micrometer carriage stop. Wanted to buy one, but Eisen doesn't offer one and PM was backordered until November (?) with theirs. I will incorporate a Contrinex NC proximity sensor that, when triggered will disable the ELS motor. The chuck will keep spinning, so cannot be used for threading, but will use it for turning to a shoulder.

This is the first version not even a prototype yet, but I hope y'allz will give me some feedback. Prox sensor will be in a sleeve that can be advanced 2mm by turning the green knob one turn (16mm / 2mm pitch thread).

Thanks for any input.

Nylon CF. Probably plain nylon would be just as good.

I started with this timing belt with 90 teeth and 0.2" pitch, 3/8" wide. Made wheels with 40 teeth each, 10mm wide (plus side walls).

Thanks, I have yet to try nylon and or CF on my X1c but i plan to do so.
