I’ve bought a Baratza Encore from a vendor who pre-installed the M2 burr which is said to improve the grinding.
The instructions I’ve seen online for the encore show it coming with a wing nut attached to the burr, and mine arrived without one. As of Day 1 Its grinding performance hasn’t had any problems.
Do I need the wing nut to keep the Encore working properly, and so should I and try to get one? Or is it not needed for the M2 burr and/or this particular model of Encore?
This question seems really basic, but I don’t see it discussed anywhere online…
