Some 3D printer motherboards have insufficient 5V power supply, which may require an external 5V power supply, which shows that the probe is difficult to push out, or the logic circuit protection main control restarts during operation. If encountered, it is generally recommended to use a DC-DC step-down module to take power from the main power supply.

1. +5V and GND should not be connected reversely for a long time, it may burn
2. Please try to keep away from strong magnets, motors, fans, and other magnetic components
3. Accidentally hitting the probe plastic rod may damage or affect the detection accuracy
4. Adjusting or reassembling the set screw of the probe requires thread glue
5. Please avoid deformation of the shell when installing the probe
6. Pulling the aluminum rod hard will damage or affect the detection accuracy
