I suspect you may have not hit second crack. Have you done more batches? That first one you posted did not look like it had hit second crack to me.So with this machine there is no progamable modes or anything like that. Essentially it's built like a blender in that you pour the beans into a glass chamber, put the chaff collector on top, and turn it on. Then you can adjust fan speed and power level (heat) up and down between 1-9 settings while monitoring the timer and temp reading. So basically you can control those variables but its up to the user to adjust those variables as needed/desired to achieve the desired roast level.
I guess where I'm having confusion is knowing how to differentiate between first and second crack if indeed first crack just kinda rolls into the second.
I asked for the same machine for my birthday. Good chance I get one.
