Brush are use if you are not using the funnel, btw can you give some picture of your grinder beans chamber area, do you use the auger without the funnel or with the funnel? my experience using the funnel only the grinder need more time to grind and with the spring auger only the grind time faster but need some brush to guide some beans or boulders stuck at far left and right side, but both funnel only or spring auger only still had problem with larger beans at finer settings the last beans sometimes can not drop to burr chamber without opening to coarser setting for short period and set back to the original finer setting after the beans drop and restart the grind process. Do you have the 5-6 gr retention experience from the beginning or after you put the spring auger?

Do you try the RDT?

I put a lower cup in there, or an espresso filter (have an old blind filter for back flush since forever), or just my hand under it.

I got the cover with the hole in it and the blower. It doesn't blow ANY grounds out. About all it does it blow blow chaff from the hopper area into the burrs.. I was hoping this would be the alternative to banging out the grinds ever time. I'm going to try leaving the grounds in there and see if it gets transferred into the next batch.

I use both the funnel and the spring. I put the spring in because I was frustrated having to brush beans into the burr chamber every time. All the beans get into the burr chamber most of the time now. I don't know where it is holding 5grs of beans, but it is. That seems really excessive to me.

I have not tried RDT because there isn't a ton of static. Do you think it would actually help with retention? I would think it would add to retention, but I'll try it.

Imho please try funnel only I think it's the less aggressive in grinding the beans, it will takes time but maybe less fines(stuck) at the chute so no need to use brush/banging the grinder as I told you before if the last beans stuck or not drop to the burr chamber at the finer setting open shortly to the coarser setting just to let the beans drop an then set back to the original settings and continue grinding back and forth, you also can rocking the handle cw and ccw back and forth this is also speeding up the grind process, some member better with RDT just try and see are those helping the retention or not.

I will share with some pictures from this morning brew session, no RDT, no banging the grinder, no brushing and no air blowing to beans chamber, just regular back and fort cw, ccw spinning the handle with shortly open to coarser setting and back to original for the last stuck beans. I always cleaning my grinder after finishing a brew session (suction with vacuum cleaner + extra air blowing from chute to clean the fines stuck) so no excessive leftovers from previous session.

19.1 grams in my target is 18/300gr ratios so I put +1gr


18.6 grams out, as I told before my retention 0.5gr - 2.0gr range in 12/15/20gr.



Using +5 clicks from the finest with funnel only.



With normal flow rate 2m:38s, a bit higher yields +18gr than my target 300gr.. :)



If funnel only or RDT not help, lastly try to deep cleaning just in case some boulders are stuck between the burr or the burr slightly miss alignment.
