The attached video shows the mechams system functioning. Its not sped up, the oozing seen is due to a too large difference between the unload and load length, which can be modified in the gcode to basically 0. All other movements etc in regards to the swapping is customizable. I think a 1 to 1.5 minute swap is achievable.

I have had an overall bad experience interacting on reddit in regards to my project.

I have therefore decided that this will be the last post on reddit related to MechAMS. The project is not over and I will continue working and expanding it to other printers with more accessories etc. Follow the other socials to stay posted for that!

-What it is

MechAMS is a fully 3D-printed automatic material system for the Bambu Lab A1.

No electronics, no boards, no wiring — just mechanics.

-Why I built it

Most AMS systems rely heavily on electronics and cost.

I wanted to explore a simpler approach that’s cheaper, more customizable, and honestly just more fun to tinker with.

-How it works (short version)

8 filament slots

Mechanical switching driven by printer movement

Custom G-code handles the process

Fully printable and modular

-Current state

The system is working reliably and close to launch.

Right now I’m mainly finishing instructions, documentation, and polishing the overall experience.

-What’s coming next

Initial launch

Proper long-form videos after launch

A1 Mini version

Launchpad + “bug bounty” style system to improve and scale faster

Ongoing revisions based on feedback

!Important note

This isn’t meant to replace existing AMS systems.

It’s a different approach — and I’m also exploring ways to combine systems.

-Feedback welcome

Let me know what you think, ideas, concerns, or questions.

I’m collecting everything into a proper FAQ so it’s all in one place

Hope this video is not too fast, i had to play with the lights to get the black to show a little, thought it would be visible in white, gray, dark gray and black. Please be kind :)
