I’ve had a strange issue start with my 2-month old P1S. Just with the last couple of prints, it’s like the toolhead is off axis by a few mm forward; by which I mean the test strips that used to print perfectly along the front of the build plate are now slightly off the front of the build plate, and when the head purges filament into the poop chute, it’s hitting the lip at the front, clumping, and dropping onto the build plate.
The picture isn’t the best but I can’t seem to upload a video unfortunately. You can see the yellow line on the chute, that’s from a multicolour print where it was constantly purging onto the rim of the chute instead of into it.
It really looks like the print head is just sitting a couple of millimetres closer to the door than it should; if everything just moved back 2-3mm it’d be perfect.
