I tried printing a key chain in the shape of a wolf (the link for thingiverse will be below), the key chain got printed fine, but during the process there were a lot of sounds as if the nozzle was scrubbing the surface of the model. I've noticed that these sounds happen more often when the printer is extruding around the edges with precise details (e.g. wolf's tail or paw). As I said it printed fine but should I be concerned?

Any answer would be apprciated

Edit: I am not sure if it's connected, but before I tried printing a small chess figure of a rook, but after an hour it started moving with the nozzle and I had to stop the process (the end result was a nicely looking bottom with a bit of "spaghetti" on it).
