Hello,
I have been using a used Ultimaker 2 at my internship for some small side projects to keep myself busy during the internship. The only problem is that the Ultimaker didn't function propperly when I started on the internship. After cleaning the ultimaker's feeder and Nozzle it started working again as long as the filament was already loose from the spool. After a few prints the Ultimaker 2 has now stopped functioning propperly once again. I've tried several things:
The nozzle has been cleaned several times, using the Atomic Method.
The feeder has been cleaned several times by disassembling it and cleaning it.
I have tried different kind of materials
The PTFE Coupler is in almost completely new state.
Yet for some reason when I try to print something close to nothing comes out of the 3D printer.
Since the point where I checked the PTFE coupler the printer is now also extruding small bits of white plastic (Almost like when your feeder grinds white material.) Even though I'm using a red PLA filament while printing.
As I said the printer is rather old and already used, it printed fine for some prints after I cleaned it when I first came here but since then it started malfunctioning.
Does anyone have an idea what I can do to fix the problem?
(As you can see on the picture, when starting it prints a small line of red and then it starts extruding little bits of white dustlike plastic.)
