cyclezib I found adjusting the 3d printed part was borderline - activated the lever sometimes, but not reliably. I would have expected my dealer to adjust that if it were the solution too. Just couldn’t move it enough, plus didn’t really like that it was a plastic hack replacing the function of the metal roller.
When I finally remember when the machine is not hot, I was going to loosen the front nut securing the switch to the front panel by a turn or two, tighten the back one - just to pull it out a little. Would love to hear if that’s not the suggested fix, as I still have a few ugly filter papers bridging the gap.
