Troubleshooting scheme:
1. Check whether the material printing temperature is in the recommended range, whether the acceleration control is enabled, and whether the basic flow is reasonable at cura slicing software
2. Whether the nozzle is too close to the platform
3. Check whether the throat and nozzle fan can be started normally
Thinking:
1. If the consumables are not at the recommended temperature, the printing will be blocked
2. The nozzle is too close to the platform, and the consumables cannot be extruded
3. If the throat and nozzle fan are not activated, it will also lead to the phenomenon of consumable plugging
