<p>My new Ender 5 Plus' Bowden tube keeps popping out of its socket on the extruder mid-print, I've tried several times and it keeps doing it even though it's locked into place securely at the start every time. Is this a known issue? And how do I resolve it?</p>
<p>I just got it so I doubt it's the coupler, I replaced it with a spare as my first solution, I did notice that it got almost stringy plastic around it whenever it gets popped out.... could that be indicative of what the problem is?</p>

There is a C-shaped clip that should go between the top lip of the sleeve and the body of the coupler that prevents the sleeve from moving and should help hold the tube more firmly.  Make sure this is installed.</p>\n<p>If the tube outside is visibly worn with scrape marks (this is rare), it might help to cut a few cm off the end so that a fresh section is gripped by the coupler.  Be sure to cut the end flush so that there is no gap between the heat break and the Bowden tube or you will have other problems.</p>\n<p>Alternately (and this is more likely), the coupler itself is worn out, possibly with bent or broken-off teeth.  If this is the case, you will need to replace the coupler.</p>\n"}, {'answer_id': 18547, 'author': 'Tristan Adams', 'author_id': 31152, 'author_profile': 'https://3dprinting.stackexchange.com/users/31152', 'pm_score': 1, 'selected': False, 'text': "<p>OK well I feel silly, it turns out it wasn't fully pushed into place, I pushed it in feeling it lock and thought it was secure, when it actually wasn't, pushing it in till it feels locked up twice resulted in it being properly secured.
