During the printing process, the filament hub motor of AMS assists in feeding the filament to the printer, reducing the resistance of the toolhead extruder to extrude the filament, and the motor will detect the resistance of the filament, when the resistance continues to be too large and the speed of filament is too small, it will prompt overload error.
The picture below: the motor of the filament hub
This error is usually caused by excessive resistance due to the following reasons:
Please refer to this wiki to check if the spool used are within the AMS specifications; check if the width of the spool is between 50~68mm and the diameter is between 197~202mm; some spools may be deformed; please rotate the spool back and forth to check whether there is too much resistance at any position.
Please avoid using filaments unsupported by AMS, such as TPU/damp PVA.
If there is wear, please refer to the wiki for replacement.
The example on the left shows a stuck spring, while the example on the right demonstrates a properly functioning spring.
Please refer to this wiki to disassemble AMS and check if the PTFE tube inside AMS is worn.
If any damage is found, please get in touch with the Bambu Lab after-sales support team for replacement.
Excessive bending of the PTFE tube between the AMS and the printer can cause additional resistance during filament feeding and retraction. Please refer to the diagram below to check for any bends.
If you have followed the above 7 steps and the issue continues to occur, please get in touch with our after-sales team for assistance.
HMS_0700_6000_0002_0001: The AMS1 slot1 is overloaded. The filament may be tangled, or the spool may be stuck.
