I notice that after a print or two, I have to heat up the extruder manually, and scrub the nozzle with a cloth to clean what the scrubber pad isn’t removing. If I don’t, when it goes to touch the corner washers, it presses down too hard and bends the platform on one or more corners.
Since it’s working on conductivity from what I read, any bit of plastic on the nozzle interferes with it getting an accurate reading and then it presses too hard on the PEI on the first few layers.
Has anyone come up with an alternate method of cleaning the nozzle? This happens even after a 2nd print on a brand new scrubber pad.
I’m only using eSun PLA at this point… perhaps its just an issue with the filament I’m using? I’ve seen it happen on some youtube videos as well.
