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..

I've had no luck with the full basket approach other than having to clean grinds out of the shower head on the machine. Still haven't sorted out a decent amount/tamp yet. Some days good - some days not so good.
