idea for feeder...

[david-ganon 2]

hi, i am a student of industrial design, i got some feedback and idea about the feeder:

the metal feeder eats the material, so i think that ultimaker should make it with rubber like wheel, and also add extra wheel that moved by the material, so the ultimaker 2 know the actual speed of the material and act by it.

thanks for listening...

A couple of folks on these threads have tried the extra wheel idea. An inexpensive rotary encoder could at least let you know if the filament is grinding.

For the feeder, I don't think that a simple rubber wheel will give you enough traction, especially with slippery filaments like nylon, but Ian has a great idea for a filament tractor: http://umforum.ultimaker.com/index.php?/topic/4393-ultimaker2-feeder-system-improvements-and-ideas/?p=52246
