Hi everyone. We use a rancilio Classe 9 (3 group USB) in our Café. We recently came across a swift grinder we were planning on implementing. When I try it out, it seems the rancilio portafilter is too big for the grinder...does that seem right? Is there a different portafilter we could use that would work for both? We have a S22 basket inside. Thanks for your help!
