I’ve never owned a 3D printer or printed anything 3D before, so I’m a complete noob here. I just got this printer a few days ago and found time to set it up today. I followed the instructions, but now I’m at the part where it says to feed filament down the tube and test the extruder. I manually pushed the filament down until I couldn’t anymore. Then I started using the feed motor control, but it can’t push it down any more either; instead it just grinds on the filament. All the while, nothing is coming out of the extruder at all.The extruder says it’s at 215C, and I’ve tried both the sample PLA and some other PLA that I bought, both are 1.75mm which is what this printer uses.I tried to google my problem and found a few similar posts, but my printer seems to be different from these. From the other posts it sounds like they can clearly see any jams simply by taking the fan off and looking inside the heatsink. But underneath my fan is some weird coil-like piece that is completely enclosed:http://ift.tt/2z5xFOR anyone help me out here? I just want to start printing 🙁 http://ift.tt/2yITh7x
