Hello, I purchased two Hemera's for a set of printers and have ran into trouble with both. I have spent the last two days diagnosing intermittent skipping with the 1st Hemera and discovered something by watching all of the gears while extruding filament. The low pitched gear that meshes with the tensioner gear is intermittently slipping on the shaft. Actually, mine now just spins freely on the shaft. (video attached) Luckily I just so happen to have multiple Hemeras on my bench I dissembled a new one and this one, the low pitched gear is firmly seated on the shaft and doesn't spin independently from the gear reduction gear. I then assembled the known good Hemera and instead of getting silent intermittent slipping, I get grinding. I checked to make sure the heat-break was not interfering with the filament gear and I have correctly set the filament tension so I am all out of ideas.
