Ok first roast results are in, I have been using a corretto up until now.
1lbs program selected
P2 selected
Time extended to maximum allowed (22:30)
400gm of Green Peru
First crack at 16:22
Roast stopped at 19:41 (Saw smoke and knew second crack was about to start)
Heard snaps of second crack begin just into the cooling period and.
I opened the door, removed the chaff tray ( I was wearing my protective oven glove)
Turned on the electric 18 volt blower a few feet from the door opening and the beans were cooled to ambient in about 3 minutes and the mesh drum was then cool to the touch.
I let the Behmor continue the cooling cycle till it stopped.
The roast is slightly darker than my normal corretto roasts, about a solid CS10.
Not bad for a first effort and time will tell on the taste.
Observations are,
Very easy to use and a lot less set up time than the corretto.
VERY EVEN ROAST
Longer time to first crack
Shorter time between first and seconds cracks.
Chaff tray handles the chaff well
Very quiet and easy to hear snaps
I agree that you have to think ahead about 20 - 30 seconds when stopping the roast
On the down side, the beans are harder to see the darker they get, even with the light on.
You have less control than a corretto but this is a roaster that you can just relax and do your weeks roasting in without any stress, I still have the corretto to muck around on if I want to profile any more
Just "burned-in" and then completed my first roast with the Behmor.
125g Mocha-Java decaf.
1/4 lb:P2:B (9min 30s)
1st crack was about 6min 30 seconds in (3:00 left on timer) - I heard just a few small cracks which then died out.
I started cooling with 1:00 left on timer, but this was too late - well into second crack (a lot of pretty obvious crackling this time) - I should have gone with 1:30 or 1:45 left on timer. The beans are pretty dark, but not charcoal at least, so it will be interesting to see what theyre like in a couple of days as espresso.
I did the roast in the kitchen under my rangehood, as there was quite a lot of smoke at the end of the roast, but the whole process was surprisingly easy - even compared to a popcorn popper. The only downside is that its not possible to cool the beans really fast. Still, I guess Ill have to see what the cofee tastes like before my final judgement.

Gday crazy,
Not sure how much roasting youve done before (ie. you may know all this), but decaf always goes VERY dark so I wouldnt worry if it looks too dark. FWIW, I seem to remember Andy recommending stopping the Mocha Java something like 5*C before second crack, which I suspect equates to a minute or so. But see how it tastes and adjust for next time!
Also, we found that decaf ages at least twice as fast as regular beans, so dont be shy to try it after only 1-2 days and make sure you finish it before 10 days old (our "turned" very quickly and tasted stale after then).
Sound like everyones having fun with their Behmors.
Cheers
Stuart.

Excellent
Roast No 4,
Peru again
Using 1 lb setting and P2, though fast-ish to 1st Crack I managed to get 3 1/2 to 4 mins between first and second by adjusting bean mass.
Based on Roast 3 and Roast 4 data it should be simple mathematics to work out the bean mass for a better profile.
Happy days.
cksyd,
are you willing to share those missing details at all? Mainly what bean mass did you use and what additions/subtractions pre/post start did you make?
Im hoping mine arrives today, and if not should definitely be tomorrow. Ill post my findings as they come in.
Is it time to make a new thread for sharing roasts and results on the Behmor?
Also, anyone who has some CS cocoa beans laying around (or if youre interested in buying some), the Behmor can roast cocoa too. Its an off label use, so to speak, so may void warranty etc (Dont know here so am warning just to be safe). Again, by altering bean mass you can get a roast more suitable for cocoa (overload so as to get a gentler roast, and stop early). The chocolate alchemy website has details for those interested.
I have come across a great piece of software called the Behmor Thing. It is a roast log designed specifically to go with the Behmor 1600 and includes things like inventory and notes for each bean as well as each roast. It also helps you work out what adjustments will actually do to the profiles - i.e. entering different times pre or post start. Also will let you log temperatures along the way if you have modded it to have a thermocouple in there. It logs all settings on the Behmor for each roast including pre and post start changes to time and hitting cool button early, even has a function to help time a preheat whilst not starting the roast log until you actually put the beans in - looks great. Mind you I have only looked at it with the sample data so far and not used it yet.
Havent put the website in case that is outside the rules, but the software is free and easily found. I hope this post in itself is not outside the rules but I assume not as it is free software and no links to commercial sites, but remove if necessary.
I have had a look at that software and it does have a lot of good things for inventory for example.
There is a discussion going on in other places on the net about what changes actually occur when using the + and - buttons before and during the roast and the software may not correctly show these changes correctly at present when it simulates the roast but there is some handy stuff there.
