Laser/lightburn not talking?

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.

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. :slight_smile:
