like i said in your other post. I don't think entirely the fault of the grinder.

And didn't your vario come with a metal tool to remove the top burr? mine did.

Yes, we removed the upper burr and cleaned thoroughly.  Will try again tomorrow.

Humidity really affects the beans a ton, thats what I meant as well, not necessarily the grinder itself directly (maybe more static on certain days?). Reason why some mornings in the summer I can pull fine then later on have to adjust if humidity has risen etc. Look at the people even with HG One and Versalab Grinders, the ones in more humid/constantly changing humidity areas have the same problems. South FL ispretty consistent for humidity, but more up north you guys can see completely out of wack humidity levels day to day causing you to chase adjustments like nutz.

Humidity affects the moisture with beans, I'm guessing on certain days causing then to absorb/retain more moisture and static. Which would explain why even with a dark roast I can get near 0-.5 gram retention, abd on more humid days can see some more clumping and retention.

Yes, but chasing the grind to the tune of blowing through 1 lb.in 2 days & getting one drinkable drink out of 1 lb.?

yeh that shouldn't happen, I'd sway more towards an issue with the bean quality (when green and roasted). I had a wack order of Redbird oncethat pulled ok then horroble after that day, never happened again with Redbird after (pulled great) go figure lol

It happened at three different places, Verve = Sermon, Stone creek , and our local Anodyne.  That's too many normally very consistent places to have a problem with all three.  Sorry.    My husband had a very difficult time getting the upper burr off (how do they expect me to do it....), but he did & cleaned the burrs real well.  Now since we lost the calibration tool that came with the machine, the book said you can use a 2mm allen wrench.  Bought one tonight & going to try re-calibrating to finer.  I was never told you had to recalibrate every few weeks like the one poster said.

We found the calibration tool & followed the exact directions to recalibrate to finer.  When moving the lever completely down on Macro & Micro, then turned on & moved Macro slowly up to 1.  It made no straining or different tone until it got to 1 on the Macro.  Then it sounded more chirpy than a tone.  Moved micro up to 1/2 mark (M).   Calibrated, but did not hear any tone change.  Moved Micro down to bottom.   Turned machine on & slowly moved up to middle- (M).  When it got to M,  the tone changed, again to a "chirpy" noise.  Don't know if that is a normal tone for the "laboring" sound one is supposed to hear.   I will try making my espresso in the afternoon to see if cleaning the burrs & recalibrating (even though it sounded chirpy) worked or not.

Dear brianl,
This thread has moved into a focus on grinders and I realize that different beans roasts are involved in everyone's postings, but I wish to return to an issue that was passed over earlier without specific mention and that is, Black Cat has the reputation of being very humidity sensitive.  One can find this mentioned frequently online.  In the future, or for new readers with these same problems, if you are using Black Cat when these problems occur, switch to a more robust roast before addressing the machine.
Also, and less elegant, if your counter top coffee cannister is large enough, a small, glass restaurant-style salt shaker can be placed inside.  Fill the shaker half full of calcium chloride granules (Damp-Rid closet dehumidifier at Home Depot/Lowes).  This will effectively pull all of the moisture out of the beans.  It will do nothing to address the damp clumps sticking to the burrs, except there may be less residue left if using 'dry beans' after several passes.  Just be careful not to knock the cannister over.  Calcium chloride does not taste good with coffee.  Refresh the CaCl2 when it gets soupy.

This calcium carbonate sounds promising, but my questions would be twofold.  One is, would this product rob the beans of too much moisture where they have another problem because they dry out too much?   Also, could this calcium carbonate somehow "leach" into the beans & be a health hazard?
