Qué hacer en su lugar
- Your printer's bed maxes out at 0°C, but PETG-CF needs at least 70°C for reliable adhesion.
- Try a compatible filament for your Markforged FX20 — PLA, PETG, and ABS are good options.
- If you need PETG-CF specifically, you'll need a printer with a hotend capable of 230°C+ nozzle.
