I bought this 7″ touch lcd last year for this exact purpose, and its been working perfectly..
I mounted it into a piece of cardboard to see what it would look like with a frame. Now to get a cnc’d black small plastic frame. And after that i’ll show a new idea! Hint ” rack cabinet !
Oh and I installed the new controller software and enabled dark theme 🙂 looks so much better now. 5.10.12
