Hello, I have 6 cetus MK2 printers for several years. Recently, many of them fail to print making a kind of wave protrude - which make collision with the nozzle on upper layer.
This causes horizontal misalignment and objects have some slided split.
Here is photos. Do I set wrong temperture setting? I use Overture PLA filament on normal PLA temp setting. Does anybody can sugges me about this issue?
