Ripples have appeared
Ripples have appeared, especially on the first few layers. I'm printing PLA. What could be causing this? I wiped the sheet with isopropyl alcohol. The filament is dried in a dryer throughout the entire print. Standard Prush slicer settings, 0.4 nozzle.
RE:
This could be caused by either the sheet not being clean or the nozzle is too close to the bed (i.e. a possible issue with bed leveling). With regard to cleaning the sheet, IPA spreads oils around on the sheet but it doesn't actually remove anything. Try washing the sheet first with dish detergent and hot water.
Also, PLA is very forgiving. Keeping it in a dry box is sufficient but you don't need to print it directly for the drier.

RE: Ripples have appeared
Those ripples are typical of Z offset being too low. In theory that shouldn't happen with a nextruder but everything is possible with the Core One, Anyway, I concur with you that a dirty bed might also be a factor to consider.
Kony, apart from following Hyiger's advice for cleaning the bed, check that the nozzle is totally free from oozing filament when the bed is probed and also if the nozzle isn't a bit loose.
RE: Ripples have appeared
looks a bit extreme for low nozzle but you can try to move the print head higher. As soon as the print starts, long press on the lcd knob until the z height adjustment tool pops up and change it to +o. 03.
I had to do that a lot for my Mk4 and Core One. For some unknown reason it suddenly seems to work fine.
