¶ What it is
A1 series printers are equipped with the nozzle clumping detection function, you can refer to the wiki for details: Nozzle clumping detection | Bambu Lab Wiki
The extrusion force sensor is used to detect whether the nozzle is covered by filament, if the nozzle is covered by filament, or if the build plate is placed incorrectly, the force on the nozzle will change. When the nozzle clumping detection is enabled, the nozzle will move outside the heat bed and then continue to move down. If the nozzle is covered by the filament, forming a thick material mass, the process of the above movement will cause the material mass to hit the heat bed and cause the force change. The change in force will be detected by the extrusion force sensor (eddy current sensor coil).
The detection process is shown as follows:
¶ Solution
- If the nozzle is covered by the filament, clean the material covered in the nozzle.
- If the build plate is skewed, and it does not affect the current printing model, you can continue with the current printing task and turn off the detection switch. This way, the printing will not continue to detect and cause false alarms. Before the next printing, be sure to place the build plate properly and enable the nozzle clumping detection again.
- In addition, foreign objects around the heat bed may also cause false detection. Please clean the foreign objects around the hot bed before printing.
