I too was one of the lucky few to snag a Bullet V1.5 from Sweet Maria’s after the March sale.
So far all I’ve done is assemble everything and run 4x 400g seasoning roasts through it. I’d planned to roast some Kenya Othaya Mahiga AA through it tomorrow but I may very well do a few more seasoning roasts since I have the dregs of a 10lb bag of sweeps from Mill City.
I’m not certain that this isn’t specific to my laptop and roaster so as always YMMV:
Use RT 2.2. Using the RT 2.3 beta, I never got the login screen and couldn’t connect to the Bullet at all. With 2.2 I was able to log in and connect to my Bullet for the first ~8 minutes of the roast. At that point RT stopped, I assume, communicating with my Bullet (no matter what I did in the software or manually no changes were reflected in RT) and I ended up with a drum high temp error.
I got beyond that and roasted another seasoning batch, number 4 I believe, and everything appeared to be working properly but from one new user to another I’d strongly recommend staying away from anything beta (I should know this) until you have your feet under you.
The Death Star, my nickname for the Bullet, is an awesome roaster. I can, and did, spend a lot of time watching it adjusting power and fan levels to hit my PH temp of 230C. It’s one of those machines that you can just sense has the ability to do really cool things if you can ever wrap your head around the logic it uses to do what it does.
I suspect the coffee rabbit hole has gotten a whole lot deeper now …
