Hi Everyone,
Having exactly the same issue here albeit with the Falcon 10W. Not showing up in terminal or LB regardless of anything suggested above. Happening on a MBP running Catalina.
Really hoping someone might find a workaround for this soon.
Thanks for the support,
Ian
I don’t have a mac or that machine, but I have Linux and some of the commands might help.
“lsusb” will list what devices are ‘hanging’ off the usb ports.

This entry from lsusb if from my Chinese led laser and yours might be the same or very similar.

There is a file where system messages are logged. I plugged in my ‘dragon’ and here’s how it shows in the log file…
dmesg usually requires root privilege … it’s also very long … pipe it though ‘tail’ to only get the ‘tail’ end of it…
jack@Kilo:~$ sudo dmesg | tail

At least you should be able to ID the device and acertain if the OS is accepting it…
If the dmesg shows ‘disconnected’, it’s not talking properly…
I hope this makes some sense to you…
Good luck
I’ve been trying to use Lightburn with my new iMac and Atomstack a20, but I’ve had the same sort of problem that others have mentioned here.
I’ve run through the recommended actions, including buying a new cable. My iMac recognises the device, but I have had to input the device details manually. However, it remains ‘Disconnected’ in Lightburn’s Laser window.
Also - in the console window, I get the message:
Waiting for connection…
Port failed to open - already in use?
How do I ensure the relevant port is open so Lightburn can function?
I’d be really grateful for help with this, as I’m new to this technology and it’s been a steep learning curve to even get to this stage.
Relevant info:
iMac specs: 24 inch, M1, 2021

There have been some users that experienced similar troubles with the falcon:Creality CV-30 Laser Falcon - #21 by tundrwd
They remedied it with a firmware update, the info is in that thread.
Thanks. Also tried this but I can’t even get the firmware to update (as far as I can tell). Laser goes into a repeating beep cycle that never ends. I’ve reached out to support but still no solution. Works fine offline, just annoyed I can’t get it to work with my Mac.
