Troubleshooting method for laser emission during RDC6685U empty range

When using the RDC6685U controller, the issue of laser emission during idle range may be caused by multiple factors. Here is a detailed troubleshooting method that can help you quickly locate and solve problems:

1. Check if the wiring is connected incorrectly
First, inspect the cable connections between the controller and the laser generator. Ensure that all cables are securely connected and that there are no loose connections or poor contact. If the wiring is incorrect or there is a poor connection, it may cause abnormal signal transmission, leading to improper laser operation. Pay special attention to high-voltage cables, laser trigger signal wires, and the laser power supply connections.

2. Check if the laser port voltage is sending a normal signal
The RDC6685U controller sends specific voltage signals to control the laser switch. During idle movement, the controller should send the correct control signal (usually a low voltage signal) to activate the laser. If this signal is abnormal, the laser generator may not receive the activation signal and therefore will not work properly. Use a multimeter to measure the port voltage to ensure it is within the expected range and meets the requirements of the laser generator.

3. Check if the laser head is connected incorrectly
If the cables and voltage signals are normal but the laser still does not start, the next step is to check if the laser head is installed and connected correctly. Make sure the laser head connection port is compatible with the controller and that the connection plug is correctly and securely inserted. Additionally, check if the laser head itself is damaged or faulty, such as verifying if the laser head power input is normal or if there is any internal short circuit or damage.
