The preamble says “suggest a time” but when I try to do that, access is “Forbidden”. FYI, it took me 1 hour and fifteen minutes to disassemble the print head.

I think it’s worth mentioning here, that you DON’T have to remember which screws (lengths) go where. It may sound obvious, but I was trying to remember where they all went, just in case it wasn’t explicitly called out later. Would have put my mind at rest, and saved some brain cells if it was stated here.

Another important step is to make sure the extruder is at half height, like it is in the picture.
