Has anybody taken apart a da Vinci Jr. 3D printer nozzle?
My first time trying to clean the nozzle after it jammed, I broke off the filament immediately before it gets heated, inside the nozzle assembly. The XYZprinting video, "da Vinci Jr. 1.0 - Advanced Nozzle Cleaning", shows the filament coming out easily when heated, but now I'm seeing that I should have cut the filament by the feeder and pulled it out after heating.
I have a long length of wire that is similar to the tiny cleaning wire that comes with the kit. Is it safe to heat up the nozzle and push the wire all the way through?
I tried pushing from the other direction with the large cleaning tool (as shown in video). I also tried heating the tip of the filament and pushing it to the jammed filament inside the nozzle and reconnecting it. It held a while as I tried wiggling it when heated but did not break the jam loose and broke off again...
What should I do?
