I could be wrong, but I'm pretty sure that machine comes with double-walled filter baskets. If you look at the baskets, they have have lots of holes when looking from the top and only one little hole on the bottom. If this is the case with yours you need to find some normal single walled baskets. I'm not sure if you can buy them, but I think others have cut the bottom layer (with the single hole) off. You'll need to do a search.
After you do this you'll hopefully find getting a good dose and grind not too much trouble. There are plenty of guides around on how to do this. Basic points to help searching are:
- use fresh beans (avoid super-market stuff) and grind fresh
- use the 5 cent test to get a dose starting point, then adjust grind to get about 30mL in about 30 seconds
- remember the 30/30 thing is just a rule of thumb to get started. I would suggest making and tasting shots on either side of this to see what effect it has and to see what you like
- it does take practice to get a nice shot reasonably consistently on that machine
Hope this helps,
