PETG-CF settings for the Voron 2.4
Great match
These are tuned starting settings for printing PETG-CF on the Voron 2.4. The Voron 2.4 has a direct-drive extruder and an all-metal hotend in an enclosed chamber, so we set the hotend to 250°C and the bed to 80°C. Carbon-fibre PETG combines PETG toughness with extra stiffness and demands a hardened nozzle.

FAQ
- What temperature should I print PETG-CF on the Voron 2.4?
- Start at 250°C for the hotend and 80°C for the bed, then run a temperature tower across 240–260°C to dial in your exact filament brand.
- What print speed works for PETG-CF on this printer?
- Around 63 mm/s is a safe starting point on the Voron 2.4. This printer can go faster once the profile is tuned, but start conservative for clean walls.
- What retraction should I use?
- Use about 1.5 mm of retraction (direct drive needs very little). If you see stringing with PETG-CF, raise retraction speed before distance and dry the filament.
- Do I need an enclosure for PETG-CF on the Voron 2.4?
- No, PETG-CF prints fine in the open on the Voron 2.4.
