Besides lubricating the axles I couldn't find any official information about periodic maintenance to the printer. I've been working with my UM2 for more than a year on an almost daily basis, what else is there to do to make sure it keeps running smoothly? Thank you.
Hello, I'm working with a friend's Ultimaker 2, to my understanding the nozzle size it comes with is 0.4mm, yet in Cura for the Ultimaker 2 machine setting every preset (Fast/Normal/High/Ult) is set to 0.46mm nozzle. Why is that so?
