Posted Sun Mar 2, 2014, 2:35pm Subject: Vario calibration, too tight OOB?
I've used my Vario for a few months without touching the calibration at all. I was getting very good shots, so I figured there was no need to touch it.
But, during a cleaning I figured it was worth checking just to be sure it hadn't shifted over time. One of the lines in the manual says:
While the grinder is running, raise the Macro arm all the way to the top (Espresso). You should not hear any change in motor speed.
However, I do, and it's noticeable. I loosened the screw several turns to the point where it seemed like it would come loose, and it still seemed to labour at that setting. Is there anything I should be changing? My espresso is still pretty good, but I want to be sure I'm not taxing the machine too hard. I'm generally running it with beans anywhere from 1R through to 3C (!) depending on the bag.
