Try a different slicer to eliminate the gcode versus mechanical problem otherwise you are chasing a ghost.

Looks like Z banding or irregular temperature on the hotend/ bed.

I've had bad filament give that effect. Try a new or reliable spool

he is using a Delta. They don't normally get Z banding due to no true Z axis. Unless his settings are way off or one pair of diagonal rods is different from the other two sets in length. Could also be a difference in tower height and a difference in home position on a tower versus the other two towers.

Re: very regular ridges on corners

just an added thought, could possibly be a small amount of play in the rod ends, but yeah - that is very reminiscent of Z banding on a cartesian. strange seeing it on something from a kossel/delta

is there any binding at all on any of the tower carriages?
does it use bearings or belts?
if belts, are they all equal in tension?
