Our Mazzer Major occasionally retains a lot of coffee grounds in the exit chute, which periodically dump out causing inconsistent dosing. It's hard to find a pattern, but it's possibly worse when it's humid out.
Is there anything we can coat the exit chute with to allow the coffee to slide out more easily? Or maybe we should polish it(?)
As for static, it already has the static screen installed on the exit, though I'm not sure what electrically grounds the chute other than the bolts – maybe that grounding path could be improved (?)
