Grinding and other noises

So, interesting noises from this new P1S… Which ones are normal and which ones are not?.. When the print starts to get taller, a grinding/scraping sound increases. As if the nozzle is scraping into the layer below. Its printing ok enough and occasionally knocking the tall objects off even with a brim and good adhesion. The build plate bounces up and down a bit too during printing. Is this normal or Not?

This happens because the default infill pattern is grid and the lines cross on the same layer causing a bump. Change infill pattern to gyroid and this will go away.
