When AMS feeds the new filament into the extruder or pulls out the old filament from the extruder, if the filament gets stuck or the entire feeding path has high resistance, it may cause the feeder motor overloaded.
2. Sometimes the filament may be caught on the edge of the spool and cannot be sent out. Please pull it out and try again.
3. If there is no tangle or sink problem, please check if the PTFE tube of this slot is bent too much or too long, which can also cause excessive resistance in the feeding path. The standard length of the PTFE tube is 580mm for slot 1 and slot 2, and 700mm for slot 3 and 4. The optimal placement of the printer and AMS is shown in the following figure 1. If the printer and AMS are placed far apart, the PTFE tube will be pulled and bent, resulting in high feed resistance, as shown in the following figure 2.
4. Please check whether any filament from another slot or broken filament is blocked inside the tool head, clean it up and try again.
5. Sometimes, the filament detect sensor of the tool head is abnormal and cannot detect the filament correctly, which can also cause overload of the AMS motor. Because even after the filament is sent to the tool head, the printer will still judge that it has not been sent to the tool head, and then continue to send the filament leading to motor overload. You can determine whether the tool head has correctly detected the filament based on the icons on the display screen or studio (green dot is displayed when there is a filament inside).
