My machine is also up and running. It arrived with couple of minor blemishes to the powder coat, but nothing like Matt's machine fortunately - certainly small enough that I won't bother ACS with them. My guess is that the machine jiggles on the rubber mounts that bolt it to the crate, and this can cause some impact effects if

It seems everyone but me has had great luck with Molykote 111 which is a NSF H1 food certified, NLGI grade 3-4 silicone based Silica thickened grease on silicone piston seals. It worked fine for me on the black rubber seals, but when I switched (many years ago) to Cafelat Blue silicone seals the problems began. The seals

Good stuff guys! Looks like I am about to go down a rabbit hole. Honestly though, if it comes to machining the carriers and what not, i'll probably not go that far

More time in Maillard isn't typically the answer. First off some coffees aren't good candidates for light roast. They may need more development to get rid of the underdeveloped notes.
