Abstract The Bambu Lab X1C firmware enforces conservative nozzle temperature limits, restricting its suitability for ultra‑high‑temperature polymers such as PPS‑CF. This article documents a minimal hardware modification—adding a 33 Ω series resistor to the hotend thermistor circuit—that enables higher actual nozzle temperatures while remaining within firmware limits. The method exploits the nonlinear resistance–temperature characteristics of NTC thermistors and provides a physically consistent temperature correction model. The goal is to approach X1E‑class hotend performance without the associated cost.
