Product Description

Upgrade your P1P/P1S 3D printer with this genuine replacement Hall Switch Board Assembly, the essential component mounted on the extruder that monitors two critical functions: filament delivery to the extruder and proper release of the cutter rod. When to Replace This Part: Visible damage or fraying of the connecting ribbon cable Persistent false alarms of filament retraction errors during printing Repeated false "cutter jam" notifications confirmed to be caused by hall sensor failure Safety First: Always power off your printer and disconnect the power cord before performing any maintenance work to avoid short circuits and electronic component damage. Wait for the hot end and heat bed to cool completely before operation, or wear heat-resistant gloves if high-temperature operation is necessary. Installation Steps (H1.5 hex wrench required): 1.Power off the printer, remove the tool head front cover, and disconnect the connecting cables 2.Press the filament tube bracket to remove the filament tube, loosen the cutter rod screw with H1.5 hex wrench to let the rod hang down 3.Disconnect the hall switch board cable, tear off the fixing tape, and remove the 2 mounting screws 4.Gently pry the assembly loose with a hex wrench through the pneumatic interface, then remove the old component 5.Align the new hall switch board assembly, press the pneumatic connector to lock it in place, and tighten the 2 fixing screws 6.Connect the ribbon cable correctly, fix it to the extruder with tape 7.Lift the cutter rod, slide it into the cutter slot, and tighten the screw 8.Insert the filament tube into the pneumatic connector, reconnect the cooling fan cable, and reinstall the tool head front cover Function Verification: After installation, power on the printer, load filament manually or via AMS, and perform a retraction operation. If the process completes normally, the replacement is successful. If issues persist, please recheck all cable connections and installation steps. This replacement part requires no additional calibration after installation, allowing you to get back to high-quality 3D printing in no time. Perfect for both DIY 3D printing enthusiasts and professional workshop maintenance.
