Your idea sounds pretty good, either 3" or 4" with an inline fan from amazon. Mounting the fan near the ceiling rafters would probably work better. A rain cap on top, the only issue I could see are possible wind gusts; one reason to get the fan closer to the roof. I'd start out with a basic no-frill inline fan

That would be pretty nice. Then it could auto alert everyone when a new green is added too

I did not like the accordion tubing that is provided. It would be very difficult to clean and I imagined it would be inconsistent if it was ever bumped or moved. As you found, changing the layout could dramatically affect your roast profiles. Not something I wanted to mess with when moving the machine or disassembling for cleaning

This is frustrating . Can you tell me how to download a video on this forum?

This is a good exchange I came across discussing whether e61s are outdated, which is where this thread might go. "Do you guys think the E61 grouphead is outdated?"

I'm on the waitlist for a Cormorant, should come up sometime in Feb 2023. I'm brand new to coffee roasting but like to fiddle a bit with things. I don't worry too much about a perfect cup of coffee and generally enjoy the process far more than the outcome. I've been watching my buddy roast on his Cormorant

I did the same thing. I always pay things off early, but i wanted to see how Affirm worked and with zero interest, there was no risk. Seemed simple enough. The first scheduled payment for me was last week but my machine has not shipped yet

Leave that up to me - I just want to know if anyone would use the aggregator if I took the time to build it

I'm replacing the exact same machine! My Micra on order is blue (week 5 of waiting). I've had my Expobar for almost 6 years and it's been a workhorse

I'd never tried Affirm before and since they were offering interest free for six months I went with that option. The first payment didn't charge until the machine shipped which was nice. No sales tax
