Panda Control Vent adds automatic vent control, printer-status lighting, and independent chamber lighting to the BIGTREETECH Panda Vent, with a browser-based interface for setup and everyday control.
- Bambu LAN integration for printer status and temperature-based automation.
- Separate vent and chamber-light colors, brightness, effects, and idle dimming.
- Optional chamber lights that follow the printer's factory chamber light.
- In-place firmware updates that preserve compatible existing settings.
- Advanced material rules for Klipper/Moonraker users.
Developed and hardware-tested with a Bambu Lab X1C. Klipper/Moonraker support is inherited and has not been independently hardware-tested by Extrusion Therapy. See testing details for coverage and limits.
You need a BIGTREETECH Panda Vent, a browser, and a shared local network for the controller, printer, and phone or computer.
Download the latest firmware, then follow the installation and update guide. Keep an official stock firmware image for recovery; the guide links to it.
Use Overview for manual vent control or Auto, Automation for temperature thresholds and advanced rules, and Lighting for the vent and chamber lights.
Vents still open after printing? In Auto, after the job ends and the bed target is off, the vents can remain open until the actual bed temperature falls below the configured closing threshold (35 °C by default). This can take a long time. Cooldown and lighting explained.
The printable model files include a redesigned riser front and brackets for relocating the original front LED boards inside the chamber. The brackets attach with double-sided tape. No GPIO or electrical modification is required. See the LED hardware map for the tested wiring and pixel layout.
