Rinkhals 20260526_04_test

on GitHub

Latest test build on the way to the June 1 stable release. This covers everything since 20260501_01 and adds a fix for a gklib crash that showed up in 20260526_02_test. If nothing else regresses over the next few days, the contents of this build will become 20260601_01.

Highlights

• KS1 firmware 2.7.2.1 is now supported (manifest, binary patches, runtime check). KS1 owners who already upgraded no longer need .enable-rinkhals on a USB drive.
• New auto-feed at print start. The touchscreen Color Match flow, Fluidd, Mainsail, USB-loaded files, and Orca remote-send all extrude correctly now after the ACE has retracted filament between prints (#464).
• New opt-in Firmware Collector app (disabled by default). Helps the community catch new Anycubic firmware faster. Never transmits certificates, account info, or personal data.
• SWU installer now keeps only the current Rinkhals install plus one previous. Frees up to ~2.6 GB on /useremain.

New Features

• MMU ACE auto-feed when no filament is loaded at print start. Race-safe task management, configurable feed length and speed via [mmu_ace] in moonraker.conf, graceful bail-out on cancel or error (#19, thanks @sharpmonk).
• Opt-in 60-firmware-collector Rinkhals app. Uses the printer's own Anycubic device certificate to discover new firmware. Sends only the public URL and version metadata to the Rinkhals community archive.
• SWU installer prunes older Rinkhals installs on every update. Current and previous are kept.
• MMU ACE shows an Unload button whenever a gate is physically loaded (#11).
• UI: download Anycubic stock firmware to USB.
• KS1 firmware 2.7.2.1 support (manifest, K3SysUi and gkapi binary patches, runtime check).
• Dev container and justfile for contributors (#12, #14, thanks @basvd).

Bug Fixes

• MMU ACE auto-feed now skips touchscreen filament refill, load, unload, and change gcodes (#20). Treating these as regular prints caused gklib to crash on K3 with "stuck at preheating" symptoms and Fluidd or Mainsail disconnecting. Detected by filename prefix (filament_refill_, filament_load_, filament_unload_, filament_change_).
• Fixed unbound filename variable in patch_mqtt_print that crashed Vanilla Klipper (#18, thanks @Kobra-S1).
• Fixed GoKlipper panic during homing on Kobra S1 Max by excluding motion_report from the exposed objects list (#17, thanks @Kobra-S1).
• Fixed process-cfg.py regex to accept indented section headers in KS1 Max config files. Also adds the missing raw-string prefix on the second regex.
• Fixed Fluidd Tool Mapping dialog deselecting on every ACE poll (#9).
• Safely verify filament_hub object exists before querying so a missing object no longer crashes gklib.
• LVGL fixes for the touchscreen UI:
  • Cast STATE enum to int for bitwise OR operations.
  • Removed unsupported lv.PART.ITEMS constant that crashed the UI when editing text fields.
  • Resolved text input dialog not showing by removing flex align assert and reverting overridden dialog method.
• hostname-dns app: fixed disabled text input and number fields by adding LVGL keyboard modal support.

Documentation

• Migrated from MkDocs to ProperDocs (#15).
• New introduction for firmware internals, plus a "how Rinkhals works" overview.
• Consolidated supported firmware versions across docs.
• Repaired invalid YAML front matter and remaining legacy links.
• Repository references migrated to the rinkhals-community organization.

Community archive infrastructure

These changes live in the rinkhals-firmware-site repository and support the new 60-firmware-collector app. Not user-facing in this build, but worth listing for context.

• New ingest Lambda and SQS FIFO queue at ingest.firmwareforge.org/v1/notify for receiving notifications from opted-in printers.
• firmware-fetcher ECS task now drains the contribution queue at the start of each scheduled run (06:00 and 18:00 UTC).
• Custom domain mapping with ACM certificate for the ingest endpoint.

Upgrade notes

• KS1 owners on Anycubic firmware 2.7.2.1: this is the first build where Rinkhals starts cleanly without .enable-rinkhals. You can remove the marker file after upgrading.
• K3, K3V2, or K3M with ACE who hit "stuck at preheating" on 20260526_02_test: please upgrade. That crash is fixed in this build (#20).
• First boot after upgrading from any pre-20260526_03_test build: the new installer will prune accumulated old version directories on /useremain. Current and previous are kept; everything else matching the YYYYMMDD_NN[_test][-N] pattern is removed. Custom folders are untouched.
