Hi @Jayd0g420, welcome here (I'm late to the welcoming party, still worth doing ) I agree with some others, if I know that combustion can happen on max, I'm happy to just run it on 4.5 or 4.75 and get consistent awesome results My hopper does a great job on 5, but definitely isn't super close to combustion, so I'm happy to run it on 5 all the time. If I got one with new internals that needed 4 for the same result, that's fine too Yeah, regarding sending back your Mighty, if I were you I'd at least wait 'til it looks like Hopper Labs have mostly cleared their backlog, so you know you can get it fixed quickly if there is an issue. I'm waiting for this myself, just for a small issue I have. I find that filling the hopper pretty full it does still get nicely evenly brown, as long as I don't tamp it down at all. I'm very happy you're having a great time with the Hopper. May it live long and happy! As for the green lights, who knows what weird and wonderful testing things they throw in @slcdbco's Hopper. We should all be so lucky (edited to add): He mentioned further up that it's blue for him, as they have been up 'til now.
