I have now printed almost daily for a month since the installation of the BIQU Panda Claw Extruder Gear Set for Bambu X1/P1/A1 Series - Golden Nano-Coated Hardened Steel Gear with Aluminum CNC Support and I have had no issues with extrusion of filament. This was a great upgrade to the Bambu Lab X1C unit. Thank you BIQU.
