I would love some for any suggestions

Hey Damian
Post your log file so I can have look at all settings - might be something there that stands out to me. Also can you say something about the coffee density and processing?
Cheers
Chris

I think I need more zones

[Damian]

The bean I roasted first was Yirgacheffe, I have a couple bags of "Panama Rati Hartmann black honey" spare so I changed to them to continue adjusting the profile, but they seem to crack a little earlier, which I think made things worse.
The last two attempts were with "Panama Rati Hartmann black honey"

Once I get the RoR smoother, I think I'll have to shift the zone times when I switch back to roasting Ethiopian beans or Geisha. Which is what I wanted to profile for, just didn't want to trash my Geisha beans

Those Rati hartmann have always been a super crashy coffee, should see what happens in a drum roaster!

[Damian]

I cupped those roasts for the last two graphs this morning.
This is a great coffee, much better than what I remember, might have to pull this one out of reject pile.

The roast from the last graph had more body and mouthfeel, very slight baked taste at the end of the first sample, but I couldn't sense it again with further tasting. In comparison, the other seemed slightly underdeveloped. I'd still like to get a smooth RoR though, to see what it can do for it.

I think I need more zones

Hey Damian, we can do more zones. I am trying to be careful about adding too much to the profile file spec just because in the end it has to be stored in the rather limited RAM of a small microprocessor, but the capacity is there for some more zones if needed. How many do you need? Also do you think that zones might need other features than the existing boost?
