Adjusting tamping pressure on a la mar...
I'm wondering if I need to adjust the tamp pressure, or the quantity of coffee portioned. Right now I have to adjust the grinder too course to achieve a good pour time. However it is so course the extraction is weak.

Before I get into your grinder I have a question, when brewing a shot what does the bottom gauge on the espresso machine read. If it is not getting to 9 bars? It sounds to me that the pump on your machine might be the problem, but without more input I cannot be of more help.
1. What is the pump pressure?
2. How much coffee is in the portafilter, ie is it tamp to the fill ring on the filter basket.
3. I am assuming that you have a Marzocco or an astoria espresso machine because you're using a swift grinder.

It is possible that the burrs on the grinder need to be replaced. However if that was already done and you are still having the problem, the adjustment for the coffee amount is behind the tall rectangular box on the grinder. Remove box (4)screws and on the left side there is a microswitch this affects the level of coffee.
