Optional: Check if the emergency stop switch (PIN23 pin) of the device is normal (this signal is high when the laser is working normally).

(1) Check if the emergency stop switch (PIN23 pin) of the device is normal (this signal is high when the laser is working normally).

(2) Whether the power supply of the laser is normal, and whether the power supply of the power supply meets the actual power supply requirements under the condition of no load and load (connected to the laser).

(3), guiding whether the optical signal is in a low state in the marking state. If the signal of the guiding light is low in the marking state (PIN22 pin is '0' level), if the signal of the guiding light is high level ('1' level), the laser is preferentially output guiding Light.

(4), PIN18, PIN19 signal is normal.

(5) Check whether the power supply wiring of the laser is correct, whether the +24V and GND are connected in reverse, and whether the ground wire is grounded.

(6) Check whether the wiring of the DB25 serial port of the laser is correctly wired according to the wiring interface.

(7) Whether the power supply of the marking card is normal, and whether the signal of the laser is normal (see the DB25 port definition for detailed signal definition).

(8), is the software setting correct?
