Hi. Just curious as to if you (or anyone) have/has made any improvements on this...? Cheers.

This is freeking awesome !! neat idea !

I would want to ditch the lead screw for a 1:1 GT2 belt drive and go with Pen-Arm mounted electro magnet and try to make it change fast. I guess for this to be really elegant needs a good software support and workflow. Very inspiring though !!

The changing of the pen looks pretty quick, but moving from left to right is dead slow. But your correct, the threaded bolt is the thing that's slowing it down.

I will upload in a bit, I dont know how or why the stl is not on here anymore. As far as firmware goes i can upload what i have, but i never could figure out how to make inskape work with it properly.

Are you going to publist the STL of the carousel?

Would be great if the firmware gets out soon to be in use before Easter.

I really like this ADD-ON! :-D
IMPRESSIVE WORK! We are printing one right now

Hi, really like this video. can you post the rest of the files and any instructions. I would love to make this for my daughters in time for Easter.

Thanks Steven

This is sooo great! Can wait for the firmware!
