Niche Zero - Dosing Cup Static
Just purchased a Niche Zero grinder and was wondering if anyone else is having trouble with static in the dosing cup?
Static doesn't seem to be any problem as the grounds leave the grinder but once I tip the cup into the portafilter about 0.25-0.5g of grounds stay in the cup.
Tried tapping the cup a few times and it doesn't seem to help all that much. Have been using the brush to get the grounds moving and then tip them into the portafilter.
Not a huge issue but it's a bit of an awkward extra step.
Any tips on how to reduce static in the dosing cup?

A trick I was taught that does reduce static, if it is a problem, is to pre measure your dose of beans into a small container (eg Decor Snack Tubs) then lightly wet the handle of a teaspoon (or similar) and stir the dose just before grinding. Experiment with doing this once or maybe twice to add just a little moisture. This certainly cured any static issues for me.
I had the same static issue. I use a bamboo skewer to stir up the grounds anyway, once I made a couple of extra swirls that went right around the edge touching all the way the static issue disappeared completely.
I noticed this as well. But I believe it'snot purely a static problem - it may be related as well, or instead, to the ridge/groove around the rim of the stainless cup. When you return the cup to the upright position you see grounds in the bottom of the cup, But I believe these grounds came from that groove and fell down when the cup was flipped back. This is why no amount of banging on the cup while it is inverted seems to dislodge them - they are simply wedged harder into the groove.
I don't have a good workaround, but a quick tap as you remove the cup from the PF easily dislodges them, unfortunately usually onto the counter top rather than the PF. A redesign of the cup so it has the ridge on the outside to stop the cup going too far into the PF but no groove on the inside would probably do the trick...
If your in a rush, static seems to be a problem. I just shake the dosing cup around and tap it on the bench a few times which helps any residual coffee on the walls to drop to the bottom. I think the static dissipates over a few seconds.
The burrs are steel but I don't think a minute amount of water (RDT) would worry them if that's your preference.
I'm going to experiment to find a way to dose directly into the PF. I know about the Decent holder but I don't necessarily want to go bottomless.
Repeating and extending some comments I made in a thread on the Lagom P64:
I quickly found that cup inversion tended to spill some grounds despite effort at shaking grounds into flatness before removing the cup from the portafilter. Now, I shake the cup before tipping (not inverting) over half in, spin the distributor, repeat those steps. If there are any grounds still stuck to the sides or base of the cup a vigorous shake will release them, dissipate the static, to tip them in. Generally, I do not find static to be a problem despite living in a dry climate area.
Compared with comments earlier in this thread, the slight difference in my actions may be the one I first mentioned, that I do not attempt to fill the portafilter in one shot from the dosing cup but shake some in, distribute, repeat. The bulk will go in readily. Any captured by the ring or still stuck by static is readily shaken loose or battered loose by other remaining grounds, whereas shaking a full dosing cup definitely does not resolve the problem.
This is the one method I haven't yet tried. Perhaps my last resort!

And just to add to my point, today I have no static issues at all! Just invert cup into PF and voila - neat pile of grounds and almost nothing left clinging to the cup insides. I assume because today it's warm here - high 20s with a winds comparatively humid. But come the cold, dry southerlies....(shudder).
