1. Do everything the same except at the first snips if first crack hit P1 then go to P3 at rolling first crack. This should take the momentum out of it, but stop it stalling.
2. Something I’ve had success with when roasting smaller, more dense coffees is using P2 auto instead of P1 and even upping the batch size a little to get the same volume of coffee you would normally have with larger beans. When doing it this way I usually need to go to 100% power and double drum speed a minute before first crack to get some momentum, but then make sure I don’t race through it too fast.
