1.4.0 Windows Crashes Every Time After Multi-Image

I have 5 images being cut in 5 cubes that are aligned in a jig. When 1 face is done, I rotate the cubes, turn off the current layer, and enable the next layer. When I hit send, every single time Lightburn crashes.

Lightburn file is available here: https://www.dropbox.com/sh/3l2dehugrmsmpwe/AAAOH2aGw-Fg56pUVD8pfclwa?dl=0 (Too big to upload here).

At least half of the time, Windows must be rebooted before it is possible to continue.

Please let me know how I can provide more useful information about the crash.

If I turn the laser off and back on between faces it avoids Lightburn crashing. Makes me think that Lightburn is not closing the operation properly.

Check if storage on the controller isn’t full or near capacity. Delete files if close to full.

File count is maxed out. How do I check capacity otherwise? Thunder Nova 35.

Even if it is full, that is no excuse for Lightburn crashing.

I don’t know if LightBurn crashing is a typical symptom but a full controller can cause strange behaviors.

See if you can delete files from the File List window. Else use the controller panel to delete the files.

Of course I can delete files, but that isn’t a solution. Files fill right back up in no time at all due to the handling of file names.

This sort of crash has not happened before. It is new in 1.4. The solution is to find the bug in Lightburn.

These are potentially 2 separate issues.

  1. Low storage will make Ruida controllers behave strangely. You need to manage files. Or avoid this by using Start instead of Send. Did you confirm that the issue goes away after clearing files?
  2. Potential issue with crashing when storage gets low. I’d suggest sending a crash report to support@lightburnsoftware.com in that case.

If you can demonstrate specific conditions where this occurs in 1.4 vs not happening in previous version even better. It may be that you hadn’t run into this scenario previously.

Please specify how I find the details for a crash report. I’m not usually a windows user.

I’d suggest sending an email to support with a link to this Topic and ask them what would be useful to help troubleshoot the crash.

Did you confirm that the issue is related to storage?

You may find the following helpful when looking for the logs of events on Windows.

Happens with 2 images as well. Removing a bunch of files didn’t change behavior.

Is this the minimum steps to reproduce?

  1. Have 2 images on one layer
  2. Send; Burn
  3. Disable layer
  4. Enable separate layer with 2 images
  5. Send
  6. Crash

If you can confirm minimum steps I’ll attempt to reproduce. Are you also using print and cut at the same time or is that not related?

From yesterday, yet the concepts remain the same. We need you to provide the exact steps you take to produce this undesirable result.

I am using 2 stacks of images in a jig, and the crash happens every time when I try to communicate with the laser after finishing a job.

It seems that Lightburn is not releasing the laser properly and then is trying to reconnect with it but Windows thinks it never disconnected (correction, rather than the laser).

The file I am using can be found at this Dropbox link (too large to upload here): https://www.dropbox.com/s/pfl7t0eiitd0w8k/Cube%20Jig%20-%20Foam%20Board%20-%204%20inch.lbrn2?dl=0

The file includes the images configured in the exact way I am using them.

I am using Print and cut to align with the top left and bottom right targets (in yellow).

I wasn’t able to recreate the crash.

But also wasn’t able to follow all the steps. Something is odd with the file so Print & Cut wasn’t behaving properly. Didn’t explore it very far.

I ran 2 images, then attempted to run a 3rd. Did not experience a crash. Note that I used Start rather than Send, however.

Other than the oddity with the Print and Cut, I noticed that the faces show up in an Image layer but don’t otherwise behave like an image. For example, Adjust Image doesn’t seem to be an option on these images. How were these images brought into LightBurn?

Other thing I noticed is that the images themselves seem unnecessarily large. Look to be about 4 MB each. Any reason for this?

Can you attempt to run these without Print and Cut and using Start button to see if the crash can be reproduced that way?

I think tomorrow I can find some time to figure out an acceptable place to cut with manual alignment.

The images were drag and dropped into Lightburn on a mac. They are grouped together, that is probably why they are not acting like images (when only one shows it’s easy not to notice).

They are sized to the cut size @ the desired DPI (3.9" x 3.9" @ 283dpi).

I have been using send and the start button.

Indeed that’s the case. Didn’t realize just how many photos there were. I’m curious if some of the hidden layers were responsible for the oddity in Print and Cut.

I can see that now after ungrouping. Surprised this results in such a large output It was sending about 4MB of data. If my math checks out this should be around 660KB.

Ok.

FWIW, crash does not occur with only one stack of images. Will report back as I do the other test tomorrow.

Note that I did 2 stacks where there was only one image on each stack actually output.

The idea is that each stack has 6 layers, one per cube face. Only one cube face can be cut at a time, then the cube has to be rotated. Using 6 layers and turning each off/on in succession has been the best solution I have found so far to managing all the cube faces.
