Firmware `2.0.0.205`

Rebased on Snapmaker's stock 2.0.0 line, which adds rainbow filament display, French language support, and a warning instead of a block for standard-flow G-code on a high-flow nozzle. See Snapmaker's release notes.

HelixScreen (Experimental)

HelixScreen is a third-party touchscreen UI for Klipper printers. Select it in firmware-config under Snapmaker Components > Touchscreen GUI (Experimental). See docs/helixscreen.md.

Filament Manager: Easily create Spoolman spools from RFID tags

Started by @Ali-Jab, built and extended by @paxx12: each channel card gets a ⊕ Spoolman action. Assign picks an existing spool, with matches for the tag suggested first. Create makes a new spool seeded from the tag.

Max Speed tweak

Built by @ni4223: Settings > Tweaks > Max Speed raises XY velocity, acceleration and tool change speeds:

	Stock	Balanced	Aggressive
Max XY velocity	500 mm/s	600 mm/s	750 mm/s
Max acceleration	20000 mm/s²	22000 mm/s²	25000 mm/s²
Tool change speed	400 mm/s	550 mm/s	700 mm/s
Tool change acceleration	5000 mm/s²	12000 mm/s²	25000 mm/s²

Run input shaper calibration first. See docs/tweaks.md.

Install

For detailed installation instructions, see the Installation Guide.

Quick steps:

Download .bin and put on FAT32 formatted USB device
On the printer go to Settings > About > Firmware Version > Local Update
Select .bin and confirm.

Troubleshooting

Custom extensions installed via SSH can break the system, and recovery may not undo them. HelixScreen is now built in: replace a manual SSH install with Snapmaker Components > Touchscreen GUI. If something breaks, try extended-recover.txt, then full-recover.txt, and only then reflash stock firmware from the Snapmaker U1 Wiki.
HelixScreen misbehaves: switch back to snapmaker under Touchscreen GUI and reboot.
Ringing or skipped steps with Max Speed: run input shaper calibration, or step down a tier.
SpoolLink: for the most reliable spool resolution, use Snapmaker's built-in RFID Detection System rather than OpenRFID.

Feedback on Spoolman/SpoolLink/Filament Manager goes in this issue.

Revert

Download .bin from the Snapmaker U1 Wiki.
Follow the same as for install.
