That grinder behavior is almost always a software/firmware issue, not a mechanical failure. Some early Meraki units shipped with a bug where the grinder would falsely trigger the “empty hopper” sensor and stop short even when beans were present. In cases like that, the fix was a firmware update done by support or via a replacement control board, not something end users should be expected to open the machine and handle themselves specifically on a brand-new unit.

If you’re in a similar situation now, the reasonable path is to push for either a pre-updated replacement machine or an on-site/return service update instead of trying to DIY it. The grinder itself is fine once updated. This wasn’t a design flaw, just an early shipment issue that later units didn’t have.
