Laser/lightburn not talking?

[Hawk1 (Hawk Honey)]

Hi

Newbie here. Have set up my new 40W FoxAlien laser, have downloaded the Lightburn software and watched the YouTube tutorial and followed it to the letter. However, if I click frame, nothing happens or if I click start I get the message that the machine may be busy or paused. I’ve seen that it might be a USB port issue, yet I run Easel through the same cable with no issues. I’ve tried different ports and connectors too, but no joy.
Can someone help please?

I don’t have a mac, but here’s a link (with a video) by @thelmuth, that should help you out…

Same idea, the K40+ models are usb/grbl.

USB will not connect. "Port failed to open" error Mac/Monport K40

This is a video I just produced that addresses how to determine if your Mac sees your laser and a couple possible fixes if it doesn’t. [Fixing Laser Connection Issues On Mac: Easy Troubleshooting Tips]

This is brilliant, thank you. As soon as I touched the devices drop down menu, the cnc moved and I was up and running in no time.
Thank you very much.
