LightBurn 0.9.22 and Mac OS Big Sur

[AlexaOttawa (Alexandra Frenette)]

Hello, I upgraded to Mac OS Big Sur and downloaded the appropriate version of Lightburn and the camera won’t update overlay. I see the laser bed in the window but no overlay. I tried running camera alignment and I do all the steps and when it’s time to CAPTURE IMAGE, nothing captures… I’ve checked all the privacy settings…

I guess no one answers…

Sorry, this slipped through but the issue you present has not. I just did a search to find @LightBurn is working this issue.

Cannot Capture Image

I can see the sequence of triggers happening, and it looks like the camera isn’t sending (or I’m not getting) the “ready to capture” event when the preview feed is moved from the initial camera selection page to the target capture page. I’ll go through that code and try to reproduce - it’s likely going to be tomorrow or the next day because I have a few other, slightly higher issues to address first that are still lingering from this release that I want to get pushed to our test group, but I sh…

Any updates yet? I’m having this exact issue right now.

Quoting our latest release announcement: LightBurn 0.9.23 released - a lot of fixes, an apology, and some news – LightBurn Software

There is still an apparent issue with camera use in Big Sur on MacOS - It’s quite possible this is a problem with the framework LightBurn is built on, but we’re actively working on it.

We’re seeing a bunch of issues on Big Sur. Camera is one, and connectivity with some lasers (specifically Ruida and TopWisdom) is another. I’m looking into it, but I don’t see anything concrete yet. I would suggest the best course of action would be to revert back to Catalina for now.

You guys have a heck of a nerve continuing to sell your cameras with no warning to Mac users with Big Sur. I have a brand new MacBook and just received my new Lightburn camera today. I’ve spent about five hours trying to get it to work only to find out you know it doesn’t work with Big Sur and you sold the camera anyway. You should have big red flashing lights that say there is a known issue with Big Sur we are working on this. And besides the camera not working I pretty much can’t send files to my laser. I downgraded to 9.22 but that has issues also. I constantly get a file error “laser is busy”. What happens now is somehow I end up with a temp file on my laser and I can’t send any files to it. I have to shut it off, reboot. Reboot Lightburn and then try three or four times to send a simple file and finally I can send one. Please please fix these issues foe Mac users.

ok- I tried the Big Sur version this morning. at first it worked for transferring files, but now after cutting, I am trying to send an updated version of the file and I get File Transfer Faild. There was a problem sending data to the laser. The machine may be busy or paused. I try hitting ESC and then try again and get the same error. I will download the Older version and try that.

[Jnbernier (Julie Bernier)]

Nope- same issue with the Older version with my Big Sur OS. I cannot send files to the laser. I am able to update Overlay with the Camera using the Older version, but not with the Big Sur version of 9.23

[Jnbernier (Julie Bernier)]

No- I only have one computer. it’s a week old. I upgraded it because I thought my old computer was the problem with not being able to send to the laser! I am using the USB cable to send.

[Jnbernier (Julie Bernier)]

by the way, I’m having the same problem with 9.22. Usually I get the file transfer error and I can escape a couple times and eventually it will send. right now I cannot even do that. I sent a file about 20 minutes ago using 9.22. I was able to cut. Now I am trying to send a revised version and I’m getting the same error and esc will not work. I closed Lightburn and re-opened. still cannot send.

@RalphU

Also from an old message…"Putting a file on a USB stick is easy - click “Save RD File” (below the stop button) and save the file to a USB stick. That’s it - you don’t need to set it up as a USB device in LightBurn - that’s only if you are connecting to the machine with the USB cable, not for using a USB stick.

Thank you Ralph.
ok- I deleted all the files on the controller, we’ll see if that helps. I have no idea what you are talking about regarding using a USB stick, I’m not using a USB stick nor do I plan to. That is a pain in the butt.
