After the machine is switched on and during the engraving process, the three indicator lights on the laser module do not light up.
2.1 There is dust in the laser module indicator light, obstructing the light.
2.2 The laser module indicator light circuit is broken.
2.3 The X-axis transfer board is damaged or the connection line between the X-axis transfer board and the Y-axis transfer board is damaged.
3.1 Refer to the video below to disassemble and clean the laser module.https://www.youtube.com/watch?v=i3noxITXZNw
3.2 If a multimeter is available, please use it to measure and troubleshoot
①Adjust the multimeter to the DC voltage range or DC 20V range.
② According to the diagram below, connect the pen while the machine remains powered on. If a 5V voltage is measured, a replacement laser module is sent; if there is no 5V voltage, a replacement X-axis adapter board and motor limit wire are sent.
After checking the above steps, if the problem still cannot be solved, please contact after-sales service cs@creality.com
