Phaetus DXC Extruder — Helical Dual-Drive for Creality K1/K1C/K1 Max | Built-in Filament Sensor

Designed for smooth, reliable extrusion on Creality’s K1 family, the Phaetus DXC Extruder combines helical dual-drive gears with an adaptive pressure rocking arm to maximize grip and minimize filament wear. The RNC-coated drive gears and multi-bearing support boost durability for long service life, while the integrated filament sensor improves print reliability with automatic runout detection. Compatible with a wide range of materials—including TPU (approx. 85A–95A)—DXC is a high-performance, drop-in upgrade for K1-series users seeking steadier flow and cleaner surfaces at speed.

Key features

• Helical dual-drive system for high grip and smooth, slip-free feeding

• Adaptive pressure mechanism self-adjusts for different filament hardness (flexibles to engineering plastics)

• RNC-coated, hardened gears for extended wear resistance (high-hardness surface treatment)

• Multiple bearings on each gear plus auxiliary U-profile bearings for stable filament guidance

• Built-in filament sensor (board-level runout detection) for reliable printing

• K1-series fit: designed for Creality K1/K1C/K1 Max (some vendors also note K1 SE; check your SKU)

• Flexible-friendly: supports TPU alongside PLA, PETG, ABS/ASA, PC, PA, and many fiber-filled blends

Specs:

• Drive style: dual-gear, helical tooth profile

• Wear surface: RNC hard coating on drive gears

• Material range: PLA, PETG, ABS/ASA, PC, PA, TPU ~85A–95A, CF/GF-filled (with proper hotend/nozzle)

• Electronics: integrated filament runout sensor

• Compatibility: Creality K1/K1C/K1 Max toolhead assemblies

• Form factor / contents: typically supplied as the extrusion mechanism (no motor); verify exact contents per SKU

Setup tips

• After installing, recalibrate E-steps and verify pressure advance/retraction.

• For flexibles, start with lower speed and moderate retraction; use a consistent filament path and check idler tension.

• Periodically inspect gear alignment and keep the drive path clean for consistent results.
