Hi Autumn, did you ‘send’ to your machine or did you click ‘start’?
try using ‘send’ and wait until it finishes sending then select ‘file’ on the controller.
If it loaded it should show on the panel.

Key is on 
Emergency stop is not engaged. And yep, laser ready button is ready. It actually just started working. On a past file I wasn’t even working on anymore… I’m so confused how this system works. I had shut everything down, reset, restarted, and still this old file is what it chose to print after I sent the new file.

I haven’t tried send. I usually use start and then walk over the machine & proceed from there. I’ll try send this time. It randomly started working just now, but not even on the file that was open on the computer. So I’m pretty confused about what’s going on.
Macs are known to have USB connection issues. I have used 2 Macbook Pros with no USB problems, however. Do a search in the forum for ethernet connection to the OMTech. I have the same model and have no problems with it connecting. You can run an ethernet cable from laptop to OMTech directly, but if you have a router, you can connect ethernet to the router then your Mac to the router.

Thanks! I’m still renovating in this office so once I get the laser in its permanent position, I planned on running an ethernet through the floorboards to connect. The USB cord currently sit across the doorway when in use so I’m booby trapped in here

Do you have files on the controller?
You could try selecting one and see if it runs.
If it does run then probably just a connection fault.
After your last post saying it seemed to work on send; understand that send does just that- it sends the file to the Ruida controller- then you press “File” on the controller and select the file to image, press “Enter.” Align the head to where you want it to start [“Origin”] press “Origin,” then “Frame” to be sure it will fit on the material you have on the bed, then press “Start/Pause” on the controller. If you still don’t get it to image- we will have to check some other things.

Anyone for the limbo? This is how I imagine you getting to the machine.
I’ve had luck this go around, but no explanation why that I can figure out! I’ve never used the “send” button. Only “Start!” So I’ll experiment next time when the project isn’t as urgent!
HAHAHA! It USED to be waist high, and then yes, this would be accurate. But the damn dogs kept walking through it an unplugging it, so it now sits about 6" off the floor, making it an excellent trip hazard.

Ok, new issue, but also the same issue. The machine will not cut a new project. It’s back to just sitting there, unresponsive.
I’ve reset the machine.
I’ve turned it off and on as well.
I removed the software from my computer and reinstalled.
I disconnected the machine within Lightburn and reconnected.
Now, when I send the art, the machine just sits there. But it worked on the last job?! And then, if I press start-pause twice, and then esc, and then the start-pause button again, it still somehow reverts to the last art piece that I don’t need cut anymore. HOW DO I GET THIS NEW FILE TO WORK?! This does not make logical sense to me.
What happens if you hold the shift key when you click start in LightBurn?
How long is the USB cable? Wondering if the signal is dropping off. Might try a cheap powered USB hub or just save files on a USB stick.

It just says at the bottom of lightburn ‘file send successful 14KB’
12’ I think?
So, if file send is successful, did you go to the laser controller to select the file and then set origin and the press Start?

It doesn’t exist on the laser. There are no files on the Ruida controller.
After you pressed send, did you go the to the laser controller to select “File” to see the files were located on the laser? In Lightburn you can check that the file went to the laser by going to “Window>File List>Refresh.”

LightBurn over USB to Ruida from Macs has been giving us issues. Searching this forum for “Mac, USB, Ruida” will return many post on this subject. 
The best option, at this point while we continue to investigate potential resolutions, is to connect via Ethernet or using the LightBurn Bridge. LightBurn Bridge - LightBurn Software Documentation
