Issues sending data to laser

LightBurn Software Questions OS Specific

Hello, I have searched this forum high and low and it’s been useful until now, though I may just be overlooking some valuable information. The issue: seems LightBurn (lb) is having issues communicating with my laser. I am running an OMTech 60 watt on a Mac desktop running Monterey 12.6.5. I am running LB’s most recent update (2.0.01)..

I don’t design in lb, only use it to send my work to the laser. I design in illustrator and silhouette business. Everything gets saved as an SVG and is then imported directly to lb. As of 2 days ago, the software will no longer communicate with the laser consistently. It keeps giving me the error message " There was a problem sending data to the laser. The machine may be busy or paused."

Let’s say I have multiple items in one file, it’ll only send one item to the laser to be cut accordingly. When I attempt to send anything else from said file, it gives me the error message.

Everything is seemingly connected.

If I use lb’s features (shapes or fonts) to do a test cut, it will cut just fine.

I have even tried to recreate many of my files in illustrator, resave, and import again, to no avail. Well, it will work once, but if I attempt to cut again, I get that same error message.

I have only ever used the “start” button to send to laser. Today, I tried the “send” and “save RD file” and it worked, but it was not consistent.

I have also changed USB cords, but no matter which ones I use, it’s still connected and showing as ready. Device is the same as is the cu.usbserial.. information. All the the same and connected and ready to go.

If anyone can provide any feedback, I would really appreciate it. If I need to provide any other details please let me know!

I know issues creep up with Mac, being state of the art and usb connections.

I’d suggest you put the Ruida on your lan and reach it by Ethernet. That connection has been pounded by anyone using a network, so it’s very dependable even if the Ruida speaks UDP.

I lasted a couple weeks with usb, finally dumped it and went with Ethernet. The only issue that’s a problem if you don’t know, is that the Ruida doesn’t use DHCP. It’s got a static ip you can only set from the console. You have to inform your router it’s static and to match the set ip to the devices MAC address.

It’s one click on my router, probably take you longer to find it. It’s well worth going Ethernet.

Good luck

Thank you for the reply! That’s very strange, I’ve been using it with the USB for years. I did consider that, but didn’t have an Ethernet cable that works. I will buy one and test it out tomorrow!

Thanks again! Will update once I test it out.

I found a working Ethernet cable and followed the steps to connect and as of now, it’s working beautifully. It did show as disconnected initially - took a few attempts of running the same steps over and over, but this most recent time seemed to do the trick. If anything is different tomorrow I will reach out. But thank you so much!!! I really appreciate you taking the time time to respond and offer assistance.

Great, I think you’ll be a lot more happy with Ethernet than with usb.

Have fun.
