Over extruding and feeding gear is grinding Ender 3 pro
It sounds like a setting mismatch between your slicer settings and the physical printer configuration. Diagnostic and informational questions follow:

Can you provide more details of your machine configuration and your slicer settings?
Are you using the Creality Slicer?
Can you also provide more information about what you are attempting to print?
Are you printing a downloaded design or your own?
Have you printed successfully before? If so, the key question would be to ask what has changed.

There are a number of settings to check, but the first one that comes to mind is the filament diameter setting in the slicer. Secondary to that would be the flow percent. Check the diameter of your filament versus the setting in the slicer. The grinding of the gear makes me think that the physical filament diameter is larger than the slicer setting.  This could explain extruding too much material and producing &quot;blobs&quot; and also the grinding.
