{"product_id":"extruder-switch-cam-for-bambu-lab","title":"Extruder Switch Cam for Bambu Lab","description":"\u003cp\u003eThe extruder switching system operates through a switching motor and transmission mechanism that drives the Extruder Switch Cam. This action causes the left and right driven wheel linkages (driven rods) to swing. A tension spring, attached to the driven rod, ensures that one driven wheel is pressed firmly against the drive wheel, enabling filament extrusion as the drive wheel rotates. Simultaneously, the opposite driven wheel remains disengaged, preventing unwanted filament movement.\u003cbr\u003eBy reversing the drive wheel's rotation, the extruder motor can selectively engage either driven wheel, enabling seamless dual extrusion using a single drive wheel.\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003e- Extruder Switch Cam*1\u003c\/p\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eH2D and H2D Laser\u003c\/p\u003e\n\u003cp\u003eH2C and H2C Laser\u003c\/p\u003e\n\u003ch3\u003eReplace H2D Dual Extruder Gears\/Extruder Switch Cam\u003c\/h3\u003e\n\u003cp\u003eThis article introduces how to replace the H2D dual extruder gears\/extruder switch cam\u003c\/p\u003e\n\u003ch3\u003eDual Extruder Gears\/Extruder Switch Cam\u003c\/h3\u003e\n\u003cp\u003eBoth the dual extruder gears and the extruder switch cam have spare parts available for replacement.

Performing tasks with the printer on can result in a short circuit, leading to electronic damage and safety hazards.\u003c\/p\u003e\n\u003cp\u003eDuring maintenance or troubleshooting, you may need to disassemble parts, including the hotend. This exposes wires and electrical components that could short circuit if they contact each other, other metal, or electronic components while the printer is still on. This can result in damage to the printer's electronics and additional issues.\u003c\/p\u003e\n\u003cp\u003eTherefore, it's crucial to turn off the printer and disconnect it from the power source before conducting any maintenance. This prevents short circuits or damage to the printer's electronics, ensuring safe and effective maintenance. For any concerns or questions about following this guide, we recommend submitting a technical ticket regarding your issue and we will do our best to respond promptly and provide the assistance you need.\u003c\/p\u003e\n\u003ch3\u003eRemove the Dual Extruder Gears\/Extruder Switch Cam\u0026amp;##x20;\u003c\/h3\u003e\n\u003ch3\u003eStep 1: Remove the dual extruder idlers and filament sensor\u0026amp;##x20;\u003c\/h3\u003e\n\u003cp\u003eYou can refer to the following Wiki to remove the dual extruder idlers and filament sensor, which will facilitate the subsequent removal of the extruder gear and cam\u003c\/p\u003e\n\u003ch3\u003eStep 2: Remove the extruder gear\/cam\u003c\/h3\u003e\n\u003cp\u003eSimply remove the cam directly.
