DIY Bambu X1C/P1S/P2S Chamber Heater Automation (n8n + Tuya + MQTT) 🔥🤖 I built a “set-and-forget” chamber heater workflow for my Bambu Lab X1C using n8n, a Tuya smart plug, and the printer’s built-in MQTT status. It automatically: Turns the heater ON only when needed Holds until the chamber is warm (when configured) Turns the heater OFF when the chamber hits target or the print ends Helps avoid the classic “left the heater running overnight” safety worry This is mainly for ABS/ASA (and other warp-prone filaments) where stable chamber temps help a lot — especially on tall / high wall-count parts. 📌 Setup guide + importable n8n workflow JSON: https://github.com/Bennyco86/BambuLabChamberHeater Slicer note: OrcaSlicer works best because it supports chamber temp + “hold until reached” Bambu Studio / Bambu Slicer needs a small Start G-code tweak (included in the repo) If anyone tries it, keen to hear what heater + placement you’re using and what chamber temps you’re running for ABS/ASA.
