¶ How to Check If My Power Adapter Is Working Properly
First, remove all accessories from the control board to eliminate any short circuits caused by accessories. You need to remove the laser, M7 solenoid valve, M8 solenoid valve, XYZA axis stepper motors, and so on.
Then, in the troubleshooting center, look for the value of DC Voltage,This value should match the output voltage indicated on your power adapter, with a normal deviation of ±1V.
¶ DC Voltage Does Not Match the Power Adapter Rating
Your power adapter may be faulty. If you have a multimeter, measure the output voltage of the power adapter to check if it's normal. If you don't have a multimeter, you can find a second power source, typically on a router, usually rated at 12V. If your device requires 24V, you can use a 12V power adapter for testing. This may not power your E80 laser module but should be enough to make the stepper motors run. If the second power source shows the correct voltage onDC Voltage，it means your primary power source is indeed faulty.
¶ How to Check If the Laser Module Is Short-Circuited
First, disconnect all the connecting wires to the laser module, and then access the troubleshooting center interface.
At this point，the DC Voltage value should match your power adapter's voltage, with a normal deviation of ±1V.
Now, try connecting the laser module wires again, and then recheck the DC Voltage value， If the value doesn't match the power adapter voltage at this point, it means your laser module is short-circuited.
