Robert's feeder; how to hold the tube in place

[emilio2 2]

Whenever I change filaments the tefflon tube (the one on the feeders top) comes out of the white collar .

Which is the right way to insert the collar/tube on the feeder in order to hold them in place all the time ?

To retain the tube you have to pull up the white collet, and then slip the bowden clip under the edge to hold it up. Without the clip it will not grip. Look at the hotend end for how the collet and clip should look.

If you've mislaid your clip then there's a discussion in the link below about printing a replacement. A paperclip can also serve as a temp fix while you print this.
