ich bin Anfänger in Sachen Linux CNC.

Hi @all, I am a beginner to Linux CNC.
My machine runs very well for me.
Now I would like to set up / installing a camera for positioning.
Does anyone know of a step by step guide for beginners?

Greeting Fritz

Thank you Andy. That's what I've seen, but it scares me a little from what I need to be entered manually, but I'll try it anyway times.
Trial and error . Thanks for your answer. Greeting Fritz

Hi@all,

is it right to start the command in a terminal?

" wget -O- psha.org.ru/debian/pubkey.gpg | sudo apt-key add - "

There starts no download

The key file definitely exists, and if you prefer you could download it separately and apply it.

thanks Andy, but that is the problem. I don't know how do this separatly, i'm absolut no Linux pro.
I only take my linux knowledge from aunt google so i dont know what i have searching about.
But thank you for your support.
