With the extruder axle misaligned I got kinda like the same print result. ( Suddenly poor print quality on two SV08's - #19 by wrusman)
The right is with the axle out of it’s position, the left is after I pushed it back end secured it
(and yes, the good print even has a filament change in it, but that is not the visible dent. That is part of the design)
