Two new Hemeras randomly grinding E3D Online 3D

nbsp 0183 32 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...

grinding wheel nomenclature

nbsp 0183 32 Use of a very thin shim while knocking off quot hangers quot can sometimes reveal the vibration of a wheel not quite dressed all the way There s another technique for quickly determining if the wheel has been fully dressed but it s a dangerous technique finger used by some seasoned grinder hands and I DO NOT recommend anybody new to grinding attempt this...
