¶ 1. Phenomenon Description
The machine starts engraving, but there are no engraving marks on the material. Only the red indicator light on the laser module is lit.
¶ 2. Cause Analysis
Laser module cable is damaged
The laser module is damaged and does not emit light
Mainboard control module port wiring is damaged
¶ Troubleshooting
If you have a multimeter, you can test it in the following steps:
① Set the engraving file parameters to 100% power, export the G-code file to a TF card or prepare for online engraving;
② Set the multimeter to "DC voltage" or "DC voltage 20V" range;
③ Unplug the wiring on top of the laser module, prepare the engraving file;
④ Connect the test probes as shown in the image below.
If the measured voltage is around 3V/5V, the laser module is faulty which needs to replace, please contact cs@creality.com by sharing the faulty report; If the measured voltage is not around 3V/5V, it means the laser module cable is faulty, please contact cs@creality.com.
