Laser cutting head is not stable

Optical fiber laser cutting machine or YAG laser cutting machine are likely to encounter in the process of using laser cutting head is not stable, it generally can be touch panel or following distance is wrong, usually due to change the cutting nozzle, cutting nozzle overheating, unequal causes of parameters.
In either case, at the end of the day or follow-up capacitance change, influence the stability of the laser cutting head.
Optical fiber laser cutting machine laser cutting head is not stable, to measure capacitance value, you can save the parameters.
Summed up the following experience, analysis of YAG equipment when this happens, how to solve.
1.
Normal after laser cutting head plate.
This is a situation in which the general parameters of the problem, it can put the laser cutting head of reduced in proportion to upper limit and lower limit, laser cutting head to follow will be normal.
2.
Laser cutting head following the distance is too high.
Open the servo debug software, observe whether following distance is correct;
Limit and lower limit, adjust the cutting head with higher proportion, test to the appropriate value.
3.
In the process of cutting, laser cutting head suddenly rise automatically.
And when this happens, the laser should stop work, careful observation, with his head copper mouth whether fever, if a fever is the laser light path is not straight, overheating, lead to copper mouth capacitance change.
Is the light path, the problem can be solved.
