New DF64V Gen 3 is blocking; zero seems to move
I‘ve received my DF64V Gen 3 a few days ago and it has some strange behaviour. When I grind at a coarse grind size for pour over then I can‘t turn the scale back to zero afterwards. It blocks at about 30-40. Only after removing the top part (the one with the dial scale), putting it back on and calibrating it, I‘m getting back to zero.
I‘ve opened the burr chamber, inspected and cleaned every part, but it doesn‘t help and I didn‘t notice anything strange. What could be the cause of the problem?
Another observation I made: When I used the grindr the first time, it produced at 10 ticks coffee of a grind size as for a french press. It was very coarse. Only after disassembling the burr chamber (inlcuding the upper burr ring), putting erverything together, calibrating it, I could really get the expected grind size at 10-20 ticks.
