I recently replaced my aging but well dialled in FLSun Q5 with an Elegoo CC2.
I am very pleased at being able to print much larger things, but I get this effect at height. This is an egregious example but even cleaner prints still have obvious layer shifts.
Is your printer set up on a good, solid countertop? If it rests on something that has any wobble, like a folding table, it can translate into poor prints. The higher off the build plate the print goes, and the faster you run the printer, the part will wiggle a bit without a solid mount. Also make sure all the frame screws are tight.
