With LB 1.5.1 Fiber laser intermittently stops

Weird
ever since updating to LightBurn 1.5.1
4 out of 5 Business cards On second pass …Fiber shuts down
switched back to 1.4.05 No issue in last 10 cards
So I switched back to 1.5.1
BAM… 3 out four same thing

Thank you for letting us know.
I’ll get this in for testing.

Would you terribly mind sharing the project file you were using at the time?
I have a machine with the exact same source and can see about debugging it.

all these and Many more
NO issues at all with 1.4

1.4





My suspicion is there still is a cache issue

@adammhaile Thank you for taking the time :+1:

I believe that Adam is asking for the .lbrn or .lbrn2 file so he can duplicate your settings.

Thank you, but what I meant was the actual project (.lbrn2) files. Those would be more helpful :slightly_smiling_face:

@adammhaile
I,ve gone back to 1.4
So do you need 1.5.1 with LB file

If willing, both Sir Nic. Might provide an interesting comparison. But yes, a 1.5.01 file (.lbrn2) where you are seeing the reported behavior would be great, thanks. :slight_smile:

Help > Generate support data, then pasting that here would also be very helpful

Thank you! Can you please also upload the .lbrn2 project file? It can be from 1.4 - that’s ok.

@adammhaile Both 1.5.1 and 1.4

1.5.1 card.lbrn2 (2.0 MB)

I might add that over 6 people in my FB Den of Lasers having same issue
some with diodes some with fiber
We have all gone back to 1.4 and no more issues
Thanks for help :+1:

@Bulldog Thank you for all this.
Unfortunately, I’ve been unable to reproduce the issue you’ve seen even running your preferences directly with the 1.5.01 released version on the same OS. I ran the file you sent (I did confirm they are identical regardless of which version saved with) 10 times. I even for the later tests attempted to load down my system heavily but they still all completed without issue.

Could you try it in 1.5.01 with debug logging enabled?
Help > Enable Debug Log
Do this right before you start the job (it’ll be a lot of data).
When do, go back to that menu item and uncheck it. Then go to your documents directory and find LightBurnLog.txt - Ideally zip it up (it’ll be quite large) and upload it here.

I keep getting disconnects from my omtech 60w mopa randomly and then lightburn hangs and i have to reboot the laser and kill lightburn and restart.

Happy to jump on a video call if needed to help solve.

With 1.5.1 still about 1 out of 8 engravings on second pass laser stops
with 1.4.05 no issues
Site wont take zip files

We still will need that debug log, could you possibly upload to google drive or similar and link us to it? We can’t debug this without it.
It’s possible that it’s something to do with an external stop trigger and the debug log would tell us. Not much changed for galvo in 1.5 - that’s the only thing we can think of.
