The reason for a laser failing to output can be complex. It could be caused by a declined laser tube, a broken laser power supply(Laser PSU), or system failure...etc.

Please follow the steps below to troubleshoot the issue.

Possible Causes

Tools

Step 1

Please check the video below and determine if the symptom is similar to your machine.
(If there is no laser output when the Beambox is running and making a loud cracking sound,
it indicates the tube is broken.)

Determine your result and the next action to take:

Step 2

Make sure the power rate and speed settings are correct in the software.

Determine your result and the next action to take:

Step 2.1

Double your power rate settings, start the task, and see if the laser outputs.
(For example, if your power rate is 15% originally, raise it to 30% and start the task.)

Determine your result and the next action to take:

Step 3

Turn off the machine.
Open the back lid and place a new double-layer tape on the first mirror.
After placing the tape, please go to Step 3.1.

• Use the Phillips screwdriver to unscrew the screw above the fan at the back of the machine, and the back cover can be opened afterward.
  
  
  
  
  
• Place the tape on the mirror to have an angle of 90 degrees against the beam.
  
  
  
  
  
• Close the back cover.
  

Step 3.1

Make 5 pulses and check if the tape has a burnt mark on it.
(Please refer to the examples to determine the result of the tape.)

A. Turn on the machine.
B. Close the lid.
C. Enter Maintain mode and wait til the homing process is done.
D. Find the Pulse button.
E. One press = one pulse, two presses = two pulses, and so on.
F. Check the tape
⚠︎ Please always make pulses when the door lid is closed.

Tape Result Examples

Good Example - Round and Strong	Bad Example - Weak, Hollow, or Not Round

Determine your result and the next action to take:

Step 4

Turn off the machine.
Open the side cover to reach the mainboard and unplug the laser control cable.
After unplugging the cable, go to Step 4.1.

• Open the side cover.
  
  
  
  
• For V18 mainboard/motherboard in green, the laser control cable is as below.
  
  
  
  
  
• For V22/V23 mainboard/motherboard in black, the laser control cable is as below.
  
  
  

Step 4.1

Please wear rubber gloves before the next action.
Turn on the machine. Press the laser force button twice or hold it for 1-2 seconds with a pen or pencil and check for laser output on the tape.
(Please refer to the examples to determine the result of the tape.)

Determine your result and the next action to take:

Step 4.2

Turn off the machine and check if the small black jumper is inserted correctly.
(The HDMI cable can be removed if you find it interfering.)

Determine your result and the next action to take:

Step 5

• Replug the laser control cable.
  • V18 mainboard in green's laser control cable location
    

• • V22/V23 mainboard in black's laser control cable location.
    

• Turn on the machine and reset the machine to the factory.
  Refer to the article, 5-18 Reset to Factory.
  
  
• After the reset, please go to Step 5.1.

Step 5.1

Use a new 2-layer tape and make 5 pulses to see if the tape has a burn mark.
(Please refer to the examples to determine the result of the tape.)

Determine your result and the next action to take:

Step 6

• Use a new 2-layer tape and put it on the first mirror.
  
  
  
  
• Raise the power rate to x1.5 and make 5 pulses to see if the burnt mark becomes stronger.
  (Please refer to the examples to determine the result of the tape.)
