New Printers & Smarter Multi-Material

This is our biggest update yet, and likely the last time we'll have to say that. We've rebuilt the way Printago models printers from the ground up. A printer is no longer assumed to be a single nozzle fed by a single spool (or an AMS); we can now faithfully represent machines with multiple toolheads and multiple filaments without an AMS, like the Snapmaker U1 or the Bambu Lab H2D. We've also had to replace all of our Bambu-only assumptions with concepts that mapped cleanly to the rest of the 3D printer ecosystem.

That new foundation is the final major piece of us becoming a complete print farm solution. It will take a little time to work through the rough edges and keep widening the list of compatible printers, but the hard architectural work is now behind us.

Elegoo Centauri Carbon 2

• Added support for the Elegoo Centauri Carbon 2. The Add Printer wizard auto-detects it over the network and prompts for an access code only if your printer requires one.
• Its four-bay multi-color canvas is fully supported. Each tray bay appears on the printer card and detail page, with the active bay marked.

Creality K2

• Full CFS (Creality Filament System) support. Loaded materials, colors, and which slot is empty appear on the printer card and detail page, just like Bambu AMS. CFS units are auto-detected, so a printer with no CFS shows just the external spool, and the slot count grows as additional CFS units are chained.
• Assign a material to the external spool and Printago pushes the color and type to the printer, so anything reading from it (Fluidd, the cloud relay) sees the change. Note: the K2's onboard touchscreen keeps its own cached view and may show the previous material until you open the spool screen on the printer.

Snapmaker U1

• Per-toolhead filament info. Material, color, and presence for each of the four toolheads appear on the printer card and detail page, sourced from RFID tags or touchscreen entries.
• Touchscreen-set filament colors and types appear even without an RFID tag and update within a few seconds. RFID-tagged spools also surface their tag ID so reels can be tracked across loads.
• Chamber camera streaming in Fuse and on the cloud printer page, with no manual configuration required.
• Chamber light, chamber fan, and part fan are all controllable from the printer card and detail page.
• U1 spools report Snapmaker as the brand and carry the per-product SKU as the material identifier, so cloud Material lookups work the same way they do for other brands.

Prusa

• Added support for the Prusa CORE One and CORE One HF, plus the rest of the PrusaLink family: MINI and MINI IS, MK3.5, MK3S, MK4, MK4S and MK4S HF, and the XL and XL 5T. Connect over PrusaLink and Printago drives prints, live status, temperatures, and controls right from the printer card and detail page.

Per-Print Multi-Material Mapping

• Multi-color prints honor the per-print material assignment on the Creality K2, Prusa MMU3, Prusa XL, and Elegoo Centauri Carbon 2, even when the physical filament is loaded into different slots than the slicer expected.

Pick Objects to Print

• In the Print Part dialog, plates with more than one object show a cube button on the plate image. Clicking it opens a visual picker where you click objects to skip them, with a badge showing the skipped count. The print starts and the skipped objects are automatically cancelled once printing begins. Works for both sliced files and unsliced project 3MFs (Bambu printers only).

Custom Print Job Labels

• Edit a job's label right in the Print Part modal. The overall label defaults to the part name (editable for STL and other single-file parts), and for 3MF files with plates each plate name is editable inline; the queue label remains <label> - <plate name>. The same label and a new plateLabels field are available on the build API for programmatic use.

Folder Watching

• Turn a local folder into a live mirror of your Printago Parts library. Point Fuse at a folder on disk and supported files are uploaded as Parts automatically. Edit, rename, move, or delete a file and Fuse keeps the cloud copy in sync, so your library follows your real design workflow (a CAD export folder, an OpenSCAD repo, a network share) without anyone clicking Upload.
• Picks up STL, 3MF (project and G-code), STEP, G-code, OpenSCAD .scad, and CadQuery/build123d .py files, and quietly ignores junk like .DS_Store, lock files, .git/, and node_modules/.
• Renames and moves within about 5 seconds are recognized as such (the cloud Part is renamed or refiled, not re-uploaded), and a choice of delete policy per folder lets a removed local file either delete or keep its cloud Part.
• Manage every watched folder from Fuse Settings: per-folder sync status (synced, pending, error, tombstoned), an error drawer that explains exactly which files failed and why, plus Pause, Resume, Resync, and Remove. A background reconciler sweeps each folder periodically to catch anything missed while Fuse was offline, and Docker installs fall back to polling automatically.

Materials

• Filament catalog expanded with over 100 vendors imported from the OpenPrintTag database, so Add Material picks up brand and product-line autocomplete for 3DJake, Anycubic, ColorFabb, Creality, eSun, Fillamentum, Hatchbox, Inland, Overture, Spectrum, Sunlu, Voxelpla, and many more. Material attributes (Matte, Silk, Carbon Fiber, Glass Fiber, Compostable, etc.) are pre-filled when you pick a brand and product line.
• Adding a missing material or variant from a printer's slot popover now opens a compact in-place form, so you can confirm or rename the variant before it's created (no more silent "Crimson"-style web-color guesses baked into your library), and the new variant is automatically assigned to the slot you were looking at.

Queue & Matching

• Pause automatic queue matching from the queue page. With auto matching off, background events stop assigning jobs and the queue stays still until you click "Match queue now", so you can stage printer and material changes without surprise prints kicking off.
• Printer matching troubleshooter now performs a live dry run for the selected job, showing accurate results for every printer regardless of its current state. Previously, busy or unready printers could falsely appear to pass material and tag checks; now you see every real failure at once and can fix them in any order.
• Fixed a bug where increasing a group's quantity created jobs the queue runner couldn't see, which could cause the queue to skip the group and pull jobs from further down.

Cameras

• Camera features are now on by default for new Fuse installs and new stores. Fresh installs enable cameras, snapshot uploads, remote streaming, and a 5-second timelapse cadence out of the box, and new stores get completion snapshots and timelapse generation turned on cloud-side. Existing installs and stores keep their current settings.
• Stopped attempting snapshot uploads from offline printers, removing the stream of "failed" entries that previously cluttered the camera activity log when a printer was powered off or unreachable.
• Fixed the snapshot poster showing a stuck loading spinner when a new snapshot arrived while the browser tab was in the background or still loading. It now loads on its own when you return to the tab.

API

• POST /v1/print-jobs/queue/group-matching returns the compatible printers for every group in the queue in one call, evaluating each group once instead of once per job.
• POST /v1/print-jobs/queue/run runs queue matching synchronously and returns the resulting (printer, job) pairs, regardless of the per-store auto-matching toggle. Requires the queue.manage permission.

Bug Fixes

• Cancelling an in-progress job from the queue now reliably stops the printer. The cancel confirmation also has a "Send stop command to the printer(s)" option (on by default) so you can clear the job without stopping the hardware.
