Thank you to the Snapmaker team for deliver the U1 to my door-step.
I’m sharing a custom firmware that adds SSH access,
hardware-accelerated camera support with WebRTC streaming,
and additional capabilities to the Snapmaker U1.

Firmware Variants
Basic Firmware
SSH access (root/snapmaker and lava/snapmaker)
USB ethernet adapter hot-plug support
Native camera integration with Fluidd
Note: Minimal risk, as there are no changes to the printing functionality.
Extended Firmware
All basic features plus:

WebRTC low-latency streaming
USB camera support with hot-plug detection
Fluidd v1.35.0 with timelapse plugin (only ability to view timelapses from Web)

Flashed “extended” version and it works really really well.
Builtin camera WebRTC stream is super responsive, low load and very nice quality.
Thank you for the great firmware @paxx12 !

I installed the extended version - everything works fine, the camera image in the Fluid interface is smooth and of good quality, SSH - I can connect (I’m not changing anything for now). Thank you “paxx12” for your work

TimeLaps doesn’t work. I check it before printing. It doesn’t record! I check it through Fluidd. !!!

Great! Any sign of the Snapmaker team integrating these changes?
Can someone tell me how to enable timelapse using the vanilla Orca? I’m not using SnOrca. I’m on extended 1.0.0

Is it possible to add that the u1 will start with any count of mounted heads?
I destroyed one and can currently not print althougth I have 3 remaining heads.
