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. New in this release: Create also works for blank or third-party tags, needing only the tag UID; anything the tag does not carry is filled in by hand.

Max Speed tweak

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

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

Heroes of this release

• @Ali-Jab: easily create Spoolman spools from RFID tags in Filament Manager
• @plastikman: firmware upgrades from firmware-config, DragonBreath M191 release temperature
• @ni4223: Max Speed tweak
• @alextac98: BIQU PopStation Mini support
• @Simon-CR: fixed-disk USB and NVMe auto-mount
• @queengooborg and @suchmememanyskill: OpenTag3D in OpenRFID
• @RrrrobertB1992: OpenRFID multicolor spools
• @noon92: SpoolLink print-start fix
• @monsterlag: firmware-config service links behind an HTTPS reverse proxy
• @rfnovo: reporting Spoolman spool creation for blank tags

Install

For detailed installation instructions, see the Installation Guide.

Quick steps:

1. Download .bin and put on FAT32 formatted USB device
2. On the printer go to Settings > About > Firmware Version > Local Update
3. 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

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