Hi all, anyone know what we can do to fix the preparation of the espresso grounds? It seems to be very clumpy (static?). The clump grate is intact… we've tried using a wdt tool to help break this up further, still too many nuggets amongst the rest of the loose grounds… the first image is how it comes out of the grinder, the second is how it looks once the wdt tool is used and basket is levelled before the third image which shows how it looks after tamping… and then the last two images are how the pucks look after extraction.
– we have a puqpress, but it seems to result in even more channelling around the edges
– the baskets are always wiped clean
– the group handles are always cleaned
– the shower screens were trash and have been replaced (they were weird cheap ones, and they spun in place even with the screw fully tightened)
– the puqpress is regularly wiped with a dry towel
I've tried using more of a coarse grind with more tamping pressure and conversely a finer grind with less pressure
We use roughly 18.5g (increase/adjust to taste) with about 38g out in 29 seconds using a medium roast pulped natural + washed Brazilian Guatemalan blend.
I've never had such bad clumping, and tbh have never used a blind shaker… I feel like there's static around the work area as you can occasionally feel a little static shock if you're touching the amplifier and something else metal… any help would be greatly appreciated

How often do you clean the grinder and did you take them apart to clean it? The dose/yield/time doesn’t sound bad at all! The last cafe I worked at has a decaf that always so clumpy like this but it extracted just fine!
When did you last clean the grinder and the clump crusher? Take off both burrs? Could be extra oil buildup in the grinder affecting it.
One more vote for grinder cleaning. Ideally these Kony E should be opened daily and vacuumed around the bottom conical Burr, use a wooden peg or toothpick to break up the compacted coffee around it.
We never had static issues in our shop, I guess make sure your stuff is properly grounded (earth wire in your outlets going to the electrical panel)
An issue I had w the Kony was buildup of fine particles if it went uncleaned for 5 days or so, leading to longer shot time, bitterness in the extraction and excessive tiger striping, but never had clumps like those.
Best of luck!
