Good afternoon guys was reccomended to this site by a frend of mine to ask for some help.I have an Ender 3 and for some reason after the 5th layer it seems to be scraping over the print as it lays, ive tried everything with temperatures and speed and even had a good tinker with the cooling fan but it still seems to be doing it and i cant understand why?Ive had a search through the forum but couldnt find it anywhere so i hope its not a total noobie question.
