Laser Power Supply (LPSU) Output Current Test Procedure
Laser Power Supply (LPSU) Output Current Test Procedure
Preface: This is a diagnostic procedure to collect data on the output of the LPSU. It is not necessary to perform this unless instructed to do so by Thunder Laser USA Support & Innovation Labs. But you can if you like. This instruction is specific to the Thunder Laser USA Nova series machines only.
Please reply back to your support ticket with your results
The Procedure:
This
procedure runs the Lightburn file and allows you to view the LPSU ammeter to
record the ma output values at the LPSU. The job will pulse at 10% and
pause briefly and then pulse at 20% and pause, and so on up to 100%.
While the machine is outputting, the operator should be recording the
values from the power supply output.
Your laser will fire during this test. It is recommended to lower the bed down and clear the bed from any materials. Position the laser head so that it is not going to burn anything below it.
Step 1: Download the attached Lightburn file
The file is a RD file, it should not be imported to Lightburn as a project, instead you will use the RD file from this link.
The file is set up to run a small set of lines in the Top Left corner using absolute coordinates.
Enable the File List Window if it is not showing in Lightburn
Use the File List window to UPLOAD the file to the machine
If you are unable to upload the File from Lightburn, then you can use a USB stick to copy it to the machine. Please see this article for details on transferring a RD file to your Thunder Laser.
Step 2: Locate Power Supply for your machine
Nova 35, 51, and 63
Located on the back of the machine, behind the blue door to the Left of the exhaust outlet
Nova 35,51, and 63 General Location
Example of the LPSU
Nova 24:
Located on the left side of your machine behind the lower blue door.

Step 3: Run Job and Data Log
Get your pen and paper ready. It would be good to make a column for 10-100% power in increments of 10 so that you will be ready to capture the output ma values.
Run the job like you would run a normal job. Record the results and email them back to your ticket.

Here is an overview of the test file.
Note that Thunder switched from running a Lightburn project file to the RD file since if you opened the Lightburn file, it would change you layer settings and cause issues after testing was complete.
Here is how the meter should respond to the test file. Please record the mA value of each pulse in order from 10% to 100%
These resources show our mA meter on the laser near the e-stop button which is an aftermarket modification
