[0.25 nozzle won't extrude Ultimaker 2+]

Often when I change filaments if it won't extrude sometimes the filament is stuck higher up in the head.  I always cut the filament to a point before sliding it into the bowden (I don't use the menu item to insert filament - I just shove it in).

 

Also I have needles that will fit even inside a 0.25mm nozzle.  I can use those to poke around if something is inside the nozzle I can push it up into the filament and then a cold pull will solve the problem.

 

I recommend you also read up on how to do a cold pull properly.  There's hundreds of posts about this and videos on youtube and descriptions at fbrc8.com and ultimaker has their own guides on doing a cold pull.

 

No idea what a cold pull is but I will look it up. I will also look for a. 25 needle

We know it was blocking. We had to unblock it. It blocks every time weary and print using 0.25

The nozzle blocks and won't feed through any of the filament. Yes it has been set to 0.25in cura.

I cannot get my 0.25nozzle to work at all on the Ultimaker 2+. Is there a trick to getting it done? The reason I need it is I am trying to print a part that has a long thing hexagonal pole and it doesn;t do it evenly in other sizes.
