I was have a problem with portafilter that fell off or loose pressure when I extract so many time, so i decided to check retail they say

"if it's doesn't hold portafilter well, you need to unscrew for a bit"

I was curious why just only unscrew so I decide to add 1mm ring to all under chamber arms end up hold thigh perfectly and not easy to loose anymore.

I also checked thickness around arms that hold chamber it's only 2mm so add 1mm ring to 3mm and that fix my issues, I think it's might can put other busket that have curve too but need to add thicker ring instead.

It's very frustrating but at least easy to check everything on my own.
