Thank you everybody, I've tried it and it works like charm! Sorry for the night picture, thought it was only dark on my monitor as I lower the brightness when I play at night, next time will definitely post a day picture! Thanks once again

Hey guys, I need a simple belt setup. I'm sending coal from the mines straight to all the machines and the belts are full with coal as it burns slowly.

I want the number 2 belt to stop when number 1 belt is full with coal. I'm still a noob with all the machines ...
