This is my first post here, let alone my first experience with a 3D printer, so bear with me if this has already been addressed.
About a month ago I started working on the Ultimaker 2 and so far my prints have turned out nicely. The sheer number of options and modifications of this printer is quite amazing(and intimidating), but for now I've concentrated on taking baby steps with my printer. So far, so good.
After getting tired of seeing the same blue filament, I decided to buy a couple rolls of PLA Red and Clear filament to change it up a bit. After receiving my new colors I removed the Blue I had and inserted the Red PLA. I properly fed my new line following the directions from the Ultimaker 2 manual and got the same results when I first had to load my Blue filament for the first time. Easy (well, not exactly easy, but I was able to figure it out with a little patience.)
Here's the problem: After loading the Red filament, it extrudes like it should with no issues. Great, I think to myself. I'm getting better at this. But when I go to print my Ultimaker robot as a test print, nothing comes out but a tiny little blob of Red. I've removed and reloaded the filament twice already and the results have been the same: After heating up and being fed through the Bowden Tube the material comes out nicely, but when it comes to printing my test print or any print for that matter, nothing comes out but that little blob I wrote about earlier. It's as if its clogged. BUT...if it were really clogged, no material would come out even during the "change filament process, correct?
Another consideration is that the filament from where it was purchased(Protoparadigm) really is 3mm instead of the required 2.85mm. I'm going to remove the Red filament here in a bit and put back the Blue filament to test that theory, but I wanted to get the input from more experienced 3Ders first, just in case I missed the obvious. Btw, I did double-check to make sure the Build Plate was properly leveled. It is.
Thanks to all in advance
