Feature Request. Auto mode that adjusts roast to achieve target end temp+time


#1

I love how the software is coming along, especially recipes! It seems so powerful. Based on the capabilities of recipes, it seems reasonable to make a mode that simply asks for your target end temp and time then it adjusts power and fan dynamically to keep a reasonable curve and achieve the target temp around the target time.

We already do this as humans operators based on a couple signals. I watch the rate of rise, note the amount of minutes it would take to hit my target temp by my target time. I drop off the power some to keep the RoR steadily declining, etc.

It stands to reason this could be done with a clever algorithm, and maybe with some modes (conductive for slower drum programs, maybe a couple different curve options) but ultimately it’s just adjusting drum/fan/power in order to get you to the correct temp at the correct time.

I believe this is sort of how preheat works. You can see the machine adjust some during preheat based on how fast it’s heating. It always seems to take about a half hour but the fan sounds different each time. (Purely speculating)

I work at a large tech company so maybe I’m just crazy with silicon valley optimism but I’d like to see an auto plus mode.

I love your thoughts Josh! And a least this would be an excellent 1st iteration to start from when cupping.

If full auto is too big a bite in one hit, one “small” tweak I would love is the predictive curve that Artisan provides on things like dry end, first crack at various points in the roast. That way mere human brains can be spared the torture of mental arithmetic of “where are we now”, “what’s my current RoR” and “when will we get where I think I want to be and does that match my target/time” - and we can just watch the pretty beans and coloured lines :wink: How about it @jacob?

I think I’m with you Stuart. In my case, full-auto roasting is of no lasting interest to me other than as a technical curiosity. I just want a really good cup of coffee. The more involved I am with its creation the better it tastes. Somehow I can overlook the crutch of s/w imagery but not my replacement thru full-auto control.

For one thing I know my coffee can’t be any better than anyone elses using that fully automated Recipe. Maybe it reflects early childhood when I didn’t want help with difficult things… “I wanna do it myself!” [ OK, I admit it- I was a PITA! :slight_smile: ]
