When we use wood cnc router to engraving work, especially when engraving relief or cutting plate, sometimes Z-axis sinking or carving deeper will occur, thus affecting the engraving effect of wood cnc router, slowing down the engraving efficiency and increasing the reject rate. So why is this a problem?

1, check whether the engraving machine control board card is loose or there are signs of damage;

2, eliminate the interference of static electricity or the surrounding magnetic field;

3. If there is any problem with the motor wire of Z axis, replace a new one to eliminate it;

4, whether there is a problem with the carving tool road file;

5. Whether the frequency converter causes interference to work;

6, control the engraving machine computer whether there is a virus;

7. Whether the operation mode is appropriate;

Generally speaking, wood cnc router Z axis out of control, mostly caused by the above several reasons, as long as we can check one by one in accordance with the instructions, I believe that to find out and solve the problem is absolutely not difficult
