After filling out a ticket thanks to some failed roasts, it was recommended that I get the firmware 595. I was hopeful but it didn’t take long to have problems. These are also the first roasts after a full cleaning of everything but the exhaust fan which is still quite clean. I also turned the cooling fan out to the side to remove the heat from under the roaster as another member recommended to try.
Roasted a 400g batch of Sumatran to the start of second crack without issue at a 220 charge temp. Roast profile is for the successful roast(funny file name is for a local business owned by a friend that likes coffee I’d never drink). After that, I was pretty confident that my roaster was good to go. Then I ramped it up to 235C for a 800g gram batch of the same beans to the end of first crack. I made it to yellowing and the roaster shot an error code(can’t even remember which one because I was so frustrated😂). This happened THREE TIMES between yellowing and first crack. I really don’t know what to do at this point. I’ve only done 7 roasts(+3 seasoning roasts) and this has happened for 4 of the 6 at 800g. 2 of them have resulted in beans I wound up having to throw away and I’m just crossing my fingers that this batch won’t be terrible. I don’t have a graph for this because it never ran long enough to save since it shut down three times😑 I actually had a cropped graph(to just before yellowing) the last time it failed. Am I going to have to stick with 400g batches? Or just run the roast ultra slow and not go to P9 at all to not have to toss my beans? Its weird because I did my 3 seasoning roasts without issue
