Laser not communicating

Hi, I have recently purchased Lightburn and i have also purchased a desktop 550MW Bachin laser from Amazon. I have manually set the laser up in Lightburn as GRBL but i am unable to connect to the laser. The firmware version is GRBL1.1F and i am running windows 10. Can anyone please assist me with the issue as i would really like to start using Lightburn.

Hi, you have to start the laser machine first and let it home then start lightburn.
Tends not to connect if you open lightburn first.

Hi, I will try this tomorrow thanks.
