I am a new bullet roaster, just purchased a R2 Pro, there is a lot of acronyms: reading forums and display on bullet. It would be nice to have a cheat sheet, so while reading or pressing the A or B button you kind of know what is going on. I know once I get the language down in a month or so…things will be easier. I am doing a lot of reading to be prepared for when my new Control housing shows up. My unit came broken, glass, usb c connector broken off of mother board. So while a wait, would like to ready your conversations, but kind of frustrating. Looking into some books beyond “Coffee Roaster’s handbook”
Here is a link to a Bullet Tip Sheet from Sweet Maria’s:
Edit: Oops, this cheat sheet is for the R2 not he R2 Pro. there are probably a lot of things that will carry over.
Sweet Maria’s does such a great job….thank you for the tip!
After all these years I never saw that tip sheet even thought I bought my R1V2 from SM 
Thanks @billc
