The laser stopped firing after a Lightburn update. I’m sure it’s a setting I need to adjust but I haven’t been able to discover which setting to change. The laser still works and I verified this by using the NEJE software. Any advice on what setting to update?
Can you see a cooling fan or power on LED at the laser head?
I have a laser controller board that is separate on one of my engravers and it can be accidentally shut off. Have a look for a little on-off push button micro-switch.
I would also check the voltage at the engraver head while being careful not to short out the power supply.
Instead let’s see if the Prefs are still in there…
Click File…
then click Load Prefs Backup
If you get a list of Prefs with various dates you should be able to select one from when it was working. It should have carried the prefs over automatically.
Is there any way you can upload the “bad” file vs a “good” file here? I’m curious to understand what could have caused this issue. You may need to change the file extension to .txt in order to upload.
John - Thank you again. I’ll follow those steps to save the prefs.
Berainlb - Are you suggesting upload the bad Prefs file? I’m willing to give it a try. When I export the Prefs file it has a .lbprefs extension. How would I change it to .txt extension? My apologies if that’s a basic question, I’m still a rookie when it comes to Lightburn.
You can simply add .txt to the end of the file or switch from .lbprefs to .txt. You would do this in File Explorer. Would be great if you can upload both the “bad” and the “good” file. Then I’ll run a comparison to understand what changed to make sense of the symptom you were seeing.
Great idea to email the prefs files… I had a recent Windows10 corruption and had to rebuild the computer. Lost my library files and prefs. Duh…backup to a different drive next time.
