The device suddenly stops during cutting. What could be the problem? How to troubleshoot?

Sudden equipment shutdown requires multi-dimensional troubleshooting:

Software and program failure:

Check whether the control software is stuck (such as file path error or G code syntax problem), restart the software and reload the program.

If the path generated by CAD/CAM software has a closed loop or out-of-limit coordinates, the graphics need to be repaired and re-exported.

Hardware trigger protection:

Limit switch trigger: Check whether the X/Y axis exceeds the mechanical travel and manually reset the limiter.

Motor overload: Use a multimeter to detect the drive temperature. If it exceeds 60℃, the heat dissipation needs to be suspended and the processing speed needs to be reduced.

Power and heat dissipation abnormalities:

Measure whether the input voltage is stable (the fluctuation needs to be controlled within ±10%), and install an online UPS to prevent instantaneous power outages.

Check whether the laser cooling fan has stopped, clean the dust and test the speed (≥2000rpm is normal).

Preventive measures: Perform an empty run test before starting the machine every day to ensure that each axis moves smoothly without jamming.
