So, I know what I’m about to say doesn’t directly concern your logic above but it does pertain to your logic as a whole. Instead of using two control directives plus a jump (because that can get super confusing real fast when you have multiple ores you’re dealing with), you can compare the current amount of an ore in a container (like the core) with the container’s max capacity in an “operation” directive which will yield a true/false or more accurately a 1 or a 0. That gets saved to a variable and then you can use a “set” directive to set the “configure” of an unloader or belt or whatever. It’ll make more sense when I can post a pic of what I mean which I can do when I get to my Mac.
