Material exits from above the nozzle (?!?)

Recommended Posts

Posted · Material exits from above the nozzle (?!?)

Goodmorning,

I have an Ultimaker 2 and I need your help please!

Yesterday I changed a coil from red PLA to yellow. Then I lunched a print but some material started exiting from the external part of the extruder. I attached a picture that depicts the issue. I would kindly like to know in which way I can solve the problem.

Thank you sooo much!

If the material is leaking between the nozzle and the block. Then probably you changed the nozzles and the new nozzle isn't tight enough.

Also.. Well you need to take out the fan cap, heat the hotend to 110-130C and with tweezers remove the leak pla.

This other user experience might help you to clean it and fix it.

Also, remember that the nozzle must be tighten while 'hot' not cold, otherwise is very easy to leave a gab where the filament can leak.

Also, when changing nozzle, it always helps to do an atomic pull before so you don't leave filament here and there that can make the installation harder.

But ofc.. Official Help guide for changing nozzles.

Other thing that could be happening is that the leak isn't on the nozzle and that did happen while printing.. Did the printed part fail and material got stuck to the nozzle?

If so, use this other guide:
