Description

🔥 CR-6 SE High-Speed Hottend Addon

This addon is designed for the Creality CR-6 SE 3D printer and allows for faster and more stable printingwhile retaining full compatibility with the original sensors.

⚙ Important Notes

• The Hottend v2 uses M3 threaded inserts from opposite sides, providing a stronger and more rigid structure.
• The upper part requires a washer to maintain proper spacing and prevent tension on the sensor system.
• If you’re using the bed-leveling sensor, make sure to use a supported mounting setup, as the Orbiter extruder/hotend can slightly bend the printer’s frame measurement system.
• Only M3 screws are needed for assembly.
• The thermistor connector (x1c) needs to be re-crimped or replaced with a JST XH 2.54 connector to fit properly.

🧠 Recommended Print Settings

It’s best to print this using Voron-style tuning presets:

• Layer height: 0.2 mm
• Walls: 3 perimeters
• Infill: 30–40%
• Material: PETG or ASA  (for higher temperature resistance)
• Nozzle temperature: 240 °C
• Bed temperature: 70 °C
• Cooling: 50–60% fan speed (avoid full cooling)

🧩 Compatibility & Tuning

• Klipper firmware is highly recommended – it helps you achieve much higher speeds and accuracy.
• Perform a PID tuning for your nozzle temperature to ensure thermal stability.
• The temperature sensor (thermistor) doesn’t need to be changed – the original CR-6 SE sensor works perfectlywith this addon.

🧰 Summary

• ✅ Fully compatible with CR-6 SE sensors
• ✅ Requires only M3 screws heating inserts and a washer
• ✅ Simple to assemble
• ✅ Enables faster printing with Klipper
• ✅ Stable temperature after PID tuning

Happy printing! 🎉
Klipper can really unlock the speed potential of your CR-6 SE — enjoy building and sharing this upgrade with the community.
