Yes, friction between the chains and the sprockets was a big issue. A bit of slop in the fit between the chain and the sprockets helps. Sanding the ends of the sprocket teeth so that the are smooth and thin at the ends where they insert themselves into the links is a must, and judicious use of DuPont nonstick Dry film lubricant slicks things up without attracting dirt.

This is where the rubber meets the road. Making that transition is a LOT of work! Congrats on figuring out the chain, and sharing the hints.

It may not be needed, but it’s absolutely spectacular! It makes me smile.

Absolutely the world needs this. Worthy of Tim Hunkin.

Wow! well done!
The world does need more Tim Hunkin creations, I agree. (I hope someday I’ll get to Novelty Arcade.) But I think I’d need to up my game quite a bit to get into his league.

That Chain! And no glue? Wonderful.
I just started playing with Arduino during the pandemic and just got the Glowforge last week. Just yesterday I was thinking that I need to put them together. Obviously not this fantastic right away.
Thanks for sharing this project!

Yep. That must be it. Weird Al says so.
That is pretty spectacular!
