The filament runs in a channel in the right hand part of the pump and is pressed against the thread by strong springs which clamp the two halves together.<br /><br />The screw thread cuts a thread in the side of the plastic as it rotates and propels to downwards.<br /><br />The "New year" extruder has one of these pumps, but it is shown without the pump fitted in the pictures.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-73939911730226389922009-05-02T02:58:00.000+01:002009-05-02T02:58:00.000+01:00Hello.

The last designs are quite easy to follow but i don´t know if this one moves the filament as the drive screw rotates. The last question is how does the "New year extruder"(http://hydraraptor.blogspot.com/2009/01/new-year-new-extruder.html) works. Does it just uses pressure to move the filament or i missed something?.<br />You are making a great job!faqundonoreply@blogger.com
