Stella Scope 0.6.0

Stella Scope 0.6.0

Released 2026-10-26. Linux x86-64 (stella-scope_0.6.0_amd64.deb) and Android (stella_0.6.0_arm64.apk). Source: AGPL-3.0.

0.4 recorded one Klipper printer. 0.6 runs a farm of them, of three kinds, and adds calibration, material profiles, print reports with timelapses, and the machine's health over time.

What is new since 0.4

A farm, not one printer

• Many printers in one service, each with its own recording. The farm wall shows every printer as an instrument cluster: state, job, time left, temperatures, camera and model. The wall fits the window and scrolls on a phone.
• Three kinds of printer: Klipper through Moonraker, Prusa through PrusaLink (CORE One, CORE One L, MK4 family), FlashForge Adventurer 5M and 5M Pro through their local API.
• Printers are found on the network or added by address. Their passwords and access codes are kept in separate owner-only files.
• A demo farm of nine simulated printers (--demo, or Add a printer › Demo) that never connects to anything.
• The camera hub: one picture source per printer, shared by the wall, the cockpit and the timelapse.
• Alerts on the farm floor, a queue, spools, backup, and Discord or Slack notices.

The cockpit

• A new look: clean instrument gauges, one family of keys, colour only for meaning. Accent, finish, dials and chips change on the fly from the Look page.
• Radial wheels for heat, fans, speed, flow and movement. Heat presets grouped by material family.
• The machine in 3D from open-licence printer models (26 printers) where they exist; the bed follows the printer's own Z direction; a view cube.
• Prusa control through PrusaLink: heat, move and the Prusa calibrations run as a command file the printer prints, only while it is idle.

Calibrate

• A pre-print setup, then each calibration the printer supports, in order: PID for nozzle and bed, Z offset, gantry levelling, bed mesh, input shaper and belt comparison, rotation distance, pressure advance, flow. On a Prusa: self test, first layer, input shaper, phase stepping, nozzle cleaning.
• What each step found is kept as a record, and a result can be written into the material it belongs to.

Materials

• Twenty materials on a fresh install, each editable: temperatures, density, price per kilogram, pressure advance, flow and fan.

Print reports and timelapses

• One timelapse picture a layer for every print with a camera, kept for the newest 40 prints (3 GB at most).
• A report per print: how it ended, print time, filament in metres, weight and cost from the material, the plate, what the printer said while it ran, and the timelapse player.

Health over time

• Belt match and X and Y resonance from each input-shaper run; each motor driver's current scaling and warnings; each heater's heat-up speed against its own usual.

Phone

• The Android app pairs with a QR code and reaches the farm directly or through an encrypted relay. At most three phones, each bound to itself.

Licence

• Free for up to five printers; demo printers never count. More than five needs a farm licence for the official builds, with a 30-day trial from the day the sixth printer is added. Terms: FARM-LICENCE-TERMS.md. Makers in the 3D3D network get a farm licence free.

Known gaps

• No Windows or macOS build yet.
• Bambu Lab printers are not supported yet.
• Prusa control is new: it works only while the printer is idle, and runs each command as a small file the printer prints.
• The timelapse needs a camera the camera hub can read; a printer without one keeps a report without pictures.
• Motor health needs drivers that report their state (Klipper TMC drivers); Prusa and FlashForge printers do not.
