Coffee Appreciation

I've moved to using full basket of coffee. Did what I thought was a lighter tamp than yesterday when it was a slow pour and today I get nothing.. nada.... zip.. I waited for 30 seconds with not a drop of coffee coming out. Doh! I gave up, rode to work and bought one :)
Looks like with the full basket I'll need to make the grind coarser still..

with that stuff you gave me from your first grind if i put the same amount/tamper as the monmouth it would not produce anything and the machine would cut out after 30+ seconds.
you need to sort a coarser grind out mate
