New to lightburn. Need advice on settings ect

I have purchased a k40 C02 laser and upgraded the board to a a mini gerbil v3.
I am having no luck with settings etc.
I would welcome all hints tips and advice on how to get results.
Thank you so much for reading

Might tell us what settings you’re having problems with. This is nothing in your post to even help us start down a debugging route.

Is it configured to home and does it? Is a good starting place…

How do you know any settings are incorrect?

Good luck
