Product Information

About this item

• 【SMART AUTO START & STOP – LOAD IT AND WALK AWAY】 —— Filament detection sensor reads the spool state in real time. Winding begins automatically when filament is loaded and stops the instant the spool is full. No manual shutoff, no overwinding, no standing over the machine. Three-stage LED confirms every stage: red flash (no filament), red solid (filament detected), green flash (winding in progress).
• 【TANGLE-FREE LAYER WINDING – BELT & GEAR TRANSMISSION】 —— Synchronous belt and gear drive maintains consistent torque from the first layer to the last. No jerking, no tension spikes, no bird-nest tangles. Every layer lands flat and even – the kind of tight, organized wind that feeds through your printer cleanly without mid-print jams or feed failures.
• 【VARIABLE SPEED DIAL – PLA, ABS, PETG, TPU, NYLON & WELDING WIRE】 —— Adjustable speed control lets you match the winding rate to the material. Dial down for flexible TPU or fine-gauge welding wire, dial up for rigid PLA or PETG. One machine handles your full material lineup without hardware swaps or reconfiguration between runs.
• 【PROGRAMMABLE SMART CHIP – REPEATABLE RESULTS EVERY RUN】 —— Embedded control chip works in coordination with the filament sensor to manage the complete winding cycle intelligently. Not just a motor switch – the chip governs start, stop, and winding behavior to deliver the same consistent result whether you're transferring a fresh 3kg roll or rewinding a partially used spool.
• 【FULLY ASSEMBLED, DESKTOP-READY – UNBOX AND RUN】 —— Dimensions: 12.6"L × 11.8"W × 7.5"H, 4.2 lbs. Compact enough for any workbench without dominating your setup. Ships fully assembled with 12V 3A AC adapter included. No build time, no calibration required – plug in and start your first transfer within minutes of opening the box.
