Third-Party Integrations
Fluidd integrates with a wide range of third-party hardware and software projects in the Klipper ecosystem. This page lists the integrations that have dedicated UI support beyond basic Klipper config editing.
Multi-Material Systems
Happy Hare (MMU)
Full dashboard integration for Happy Hare-managed multi-material units (ERCF, Tradrack, and others).
Features include:
- Gate map visualization and filament status
- Tool management and maintenance dialogs
- Clog and tangle detection via Flowguard
- Sync-feedback buffer rendering
- Espooler display
- Endless spool support
Requires Happy Hare installed on your Klipper instance. Fluidd will
automatically show the MMU dashboard card when it detects the mmu Klipper
object.
AFC (Automated Filament Changer)
Dashboard card for AFC Klipper Add-On hardware (TurtleNeck, BoxTurtle, and others).
Features include:
- Hub and lane management
- Buffer status monitoring
- Extruder control
- LED state and stepper monitoring
Requires AFC-Klipper-Add-On installed on your Klipper instance.
Probes & Sensors
Beacon
Fluidd includes a Beacon eddy current probe widget that appears automatically when the probe is detected. From this card you can view probe samples, manage saved probe models, and save new models directly from the UI. No extra Fluidd configuration is needed.
Cartographer / Scanner
Probe commands for Cartographer and Scanner devices are integrated into the Toolhead card. Two calibration methods are accessible directly from the Toolhead card when the probe is detected:
- Scan calibration — performs a full bed scan for mesh generation.
- Touch calibration — uses physical touch for Z offset calibration.
No extra Fluidd configuration is needed; the buttons appear automatically when Fluidd detects a Cartographer or Scanner probe.
Other probes
Any probe configured in Klipper ([probe], [bltouch], [smart_effector]) is
automatically visible in Fluidd's Toolhead card with its current state. This
includes Smart Effector, Probe Eddy Current, and Load Cell sensors.
No extra Fluidd configuration is needed.
Temperature & humidity sensors
Any sensor Klipper exposes is shown automatically. This includes AHT10/20/30, BME280, BMP180/388, SHT3X, HTU21D, LM75, PT100/PT1000, and more. See Thermals for configuration examples.
Kalico Firmware
Kalico (formerly Danger Klipper) is a community fork of Klipper that adds advanced features for experienced users. Fluidd detects Kalico automatically and adapts its interface — no extra configuration is needed.
Kalico can be installed via KIAUH as an alternative firmware.
Features exposed in Fluidd
| Feature | Description |
|---|---|
| MPC (Model Predictive Control) | An alternative to PID for extruder temperature control. When configured (control: mpc in [extruder]), Fluidd shows an MPC_CALIBRATE button in the thermals card. See the Kalico MPC docs. |
| Non-critical MCUs | Mark microcontrollers as optional with is_non_critical: true in [mcu]. Fluidd gracefully disables controls for disconnected optional MCUs instead of showing errors. |
| Dockable probes | Native support for Quickdraw, Klicky/Unklicky, and other dockable probe systems without external macros. |
| Per-axis acceleration | Independent X/Y acceleration and velocity limits for CoreXY and CoreXZ kinematics, shown in the Toolhead card. |
| Fan curves | Temperature-based automatic fan speed curves. |
| Python templates | Python math library available in Jinja2 macro templates for complex calculations. |
| G-code shell commands | Execute shell commands directly from macros. |
| Firmware retraction with Z-hop | Built-in Z-hop support during firmware retractions. |
For the full feature reference, see the Kalico documentation.
Companion Services
Spoolman
Filament spool tracking with QR code scanning, toolchanger support, and print-start sanity checks. See Spool Management for details.
Timelapse
Render and browse timelapse videos via Moonraker's timelapse component. See Timelapse for details.
Crowsnest
Recommended camera manager for Klipper setups. Fluidd recognizes
crowsnest.conf in the config file editor. See Cameras
for supported streaming types.
KlipperScreen
Fluidd recognizes klipperscreen.conf for editing in the config file editor.
Obico
Obico (formerly The Spaghetti Detective) provides remote access to your full Fluidd interface from anywhere, AI-powered print failure detection, and mobile apps for iOS and Android. It is 100% open-source and can be self-hosted. Follow the Obico setup guide to get started.
OctoEverywhere
OctoEverywhere is a cloud service with a free tier that provides remote access to your Fluidd interface with full-framerate webcam streaming. Premium plans unlock Gadget AI print failure detection, real-time notifications via Telegram, SMS, and Discord, and mobile app support via Mobileraker and OctoApp.
