I have a K40 and have a cohesion board on the way.

I have a K40 and have a cohesion board on the way. I have installed LW4 to start learning it.

I do not get a CAM tab on the left side- I can open files and see config stuff, but no CAM tab.

I do not have a machine connected, I am just trying to learn to develop a cutting program.

Have I missed something in the install? It all ran without error.

Welcome. This is that you should see.
I have some videos on how to do basic stuff, search for them on YouTube

Thank you, that is what I see. But there are some videos on the web that show a CAM tab. I guess that was on older versions.

The CAM tab where you create all the operations is the Files TAB

Welcome to the club!
