The main problem with the K2 Plus printer is the spring inside the extruder, which is too strong. Replace it with a weaker one, and you won’t have to disassemble the extruder anymore.
Appreciate a link to the weaker spring that works for you.

Sorry, I don’t have a link, but here’s how I solved it. I took the strongest spring I could find from a ballpoint pen and replaced the original one. Ever since I did that, I haven’t had any issues with the extruder.
