Teflon tube is sliding off from teflon insulator...

Recommended Posts

Posted · Teflon tube is sliding off from teflon insulator...

After another break I start getting problems with some brown thing blocking nozzle (I tried to clean nozzle and hot end using high temperature flame) and just after that for some reason, teflon tube is sliding off from teflon insulator...

Any one had problem with it ? I just had to print several prints for my own printer but of course UM stop working just before I start printing mount for hot end :(, but seems that if I won't be able to repair it I will be forced to try to cut it from wood/aluminium on CNC...

I don't see a reason why it start sliding off....

Any one interested with buying Ultimaker (from August 2013) with heated bed and heated chamber (acrylic sheets on hinges) ?

UM located in UK.

"Bowden Popping"

You need to either: 1) print a thicker bowden-retaining clip and use it, or 2) re-tighten your hotend thumbscrews with more pre-loading compression on the bowden tube.

Should be an easy fix.
