Dry your filament immediately before printing — PC is extremely hygroscopic. Even 2–3 hours of moisture exposure degrades print quality.
This printer has an enclosure — keep it closed throughout the print to maintain chamber temperature.
Use a hardened steel nozzle for filled variants (glass-fiber, carbon-fiber) — standard brass wears quickly.
PC is one of the most warp-prone materials. A brim of at least 5mm and an enclosure chamber above 45°C are strongly recommended.
