Hi! 
Ever since the first glimpses of the Sidecar project, I’ve been looking forward to a full MMU implementation for the Snapmaker U1 — the kind of seamless multi-material experience Bambu Lab offers with their AMS units.
Now, thanks to decay71’s work (and many others), multiACE is in the works — and I’ve been building on top of it to bring proper ACE multi-material support to the U1 inside a Snapmaker Orca fork.
A sneak preview of what I’ve been working on:
- Live ACE filament inventory, read straight from the printer
- A smart sync dialog showing U1 toolheads and ACE slots together
- Topology-aware colour mapping → ACE is connected to T4, so T4 is disabled. Instead ACE filaments (A1-S1 to A1-S4) can be selected
- A layout that scales to a full setup of 4 ACE units and 16 spools
It’s an evenings-and-weekends passion project, with no promises on if or when it’ll be ready for everyone. I keep at it because the U1 is a genuinely open platform, and that openness is what lets enthusiasts experiment and build things that make it better for all of us.
If my work is useful to you — or you just want to keep the late-night hacking going — a coffee would be appreciated :). Thank you!
