Hello, I just print yesterday funnel, and when I wake up, I see its print in the air.... I pause the print and see what's the problem. And I see the spool of the PLA disconnect from the printer, and its continume to printe in the night, but without PLA. So to remove the piece of PLA got stuck in the printer I was do UNDO meterial 1, but the PLA no outgoing from the printer. What I can do to remove the piece got stuck in the printer?????

You can remove those clear tubes - easy to do.  They are called "bowden tubes".

 

First realize that the two ends are different so don't put the tube in backwards when done.  The end on the feeder has an internal taper - like a funnel.

 

To remove first remove the little white clip.  then push down firmly on the white ring (collet) - this is best done with a tool such as pliers or screwdriver.  While pushing down firmly on the collet lift the tube out.  To put it back together push the tube back in and while holding the tube down slide the clip back under the collet.  

 

By the 30th time you do this you can do it with your eyes closed.

If you want to remove the horse-shoe clips and bowden tube much easier, print these clips. You can easily grab them with your fingers. Find the models on my page (scroll down until you see them):
