I finished my first roll of filament this week. So I wanted to change it to a new roll. Which I was expecting to be really easy. But it turned out to be a disaster.
There are several things which went wrong during this process, which I will highlight here below.
The problems started with not being able to push through the new filament. I pressed the button and tried to put through the filament. Something I thought went very well at first. Cause I could insert it, and the filament disappeared into the module. But… It did not come out of the nozzle. Plus I heard something which sounded like the filament hitting a fan.
Obviously, I subtracted the filament back immediately. Then I opened the module to see what went wrong. Which brought me to the second problem. I noticed in a video which explains how the nozzle should be changed (https://www.youtube.com/watch?v=3dSHRMNjkGo), that I am missing some screws. The one at the bottom (next to the nozzle), and one which is in between the two outer screws of the heatsink. The wires cannot be pulled out which makes me think that the nozzle is cluttered with filament and that the wires are molten together with the PLA.
Can someone help me telling what to do? So I can change the filament and start printing again.
