Hi all,
I'm having issues with my espresso set-up. So many issues that I've become quite disheartened with the whole process. I have a Diadema Perfetta single boiler and a Compak K3 Touch grinder. Years ago this combo was working brilliantly for me... But the issue that I have now is that the grinder does not seem to be able to get fine enough for espresso. If the grinder does get fine enough, it chokes up on the next grind and refuses to grind. I can hear the motor trying to work, but the burrs don't spin. I took the grinder to get it serviced a few months ago, the guy did say these grinders can get clogged with fines and refuse to grind. He cleaned it out with compressed air and lubed the top burr and gave it the all clear. The problem came back pretty quickly. I then took it to a highly regarded espresso company offering a free training course. With a kg of their beans we dialed in the grinder and the grinder gave us no problems at all (typical). When I took it home and tried my beans the problem returned. Most of the time (at home) I'm using home roasted beans, but I have nought beans from a local cafe and experienced the same problem.
I'm wondering if the problem could be one of the following:
I would appreciate any help anyone can offer. I really want to sort this problem out, I miss the days when my set-up was working without issues... I'm happy to provide any extra information you might need.
Please help me!

I'm wondering if the problem could be one of the following:
- I'm using a convex tamper? I've had this since I bought the machine and had no troubles whatsoever
- Home roasted beans? Could they be too fresh?
- Could this be caused by a roast that is too light?
