All the best!
Just wondering if someone could help me out also,
I have a breville dual boiler and smart grinder pro. Im roasting my own beans but I'm finding even on finest setting, burr setting 1,2 or 3 even and on LCD 1 shot at times still can run too fast for my likes. I haven't yet chocked the machine either so not sure whats going on.. I'm also using 20-23 grams in the basket and tamping pretty firmly.
