I got parts this week from Baratza to try and upgrade my Vario. It seemed to go well until I started grinding.
I calibrated to hear the burrs start to touch at 2Q then put it up around 2E and ran a first dose through. It didn't sound entirely happy but it made a nice fluffy pile in the basket. It didn't generate much pressure while pulling the shot, but that's complicated by another issue with my Andreja (thread). It did create one of the 'bloomiest' flows out of the bottomless portafilter I think I've ever seen despite using ~10 day old beans.
I was going to click up the grind a bit to see if I could get a little better pressure and realized it was no longer calibrated properly so I calibrated to 2Q again. Then I took two videos, first with an empty hopper so you can hear what it sounds like as I click into ~2E: Then another of the actual grind at that setting: After that it was out of calibration again with the 'touching' sound coming on around 1E.
- Forte chamber & new motor plate
- Forte burr carrier
- New belt
I'll tear it down again tomorrow and see if there's something obviously wrong. I haven't found videos yet showing how to replace the lever arms and whatever the thing is called that actually levers the lower burr carrier up and down. It seemed to be straightforward to remove it from the old motor plate and transfer to the new, but maybe I am missing a trick there.
I'll also check belt tension again as that could explain nasty noise (but not the slippery calibration).
If I don't sort it out tomorrow I'll try Baratza support Monday. They've been great.
