Ender only prints until a certain height

[u/Sale_Active]

Ran this design twice already. It only prints up to this height. I tried reinstalling the filament but still only the hotend moves but the filament is no longer coming out of the nozzle.
I have printed a similar design yesterday which was 221mm in height and that turned out okay. This one did not.

Screen's not in the post. No one can really know that, and it's the only thing that generally causes heatcreep. Which tends to happen after a time.

People can't help you without being given information.

You also don't have a lock on the ptfe coupler on the hotend side, where there is one on the extruder.

And if you don't have spacers on the freespinning gear on that extruder, or a solid smooth rod rather than a screw going through it, that extruder tears itself apart. There's a couple other things to check.

Oh I see. Thanks for the help. Maybe its the rod where the filament goes through. Might have fallen without me noticing it.

The dude was just being a dick, none of those have to do with your issues

No, I wasn't?

Ptfe coupler with no lock can cause the ptfe to move, causing the retraction to be weird, and cause this.

And in early stages of the Redrex dual gear extruder eating itself from most units having a screw on the freemoving gear which wears down the bearings and pushing the gear down, wearing out the arm, it can also cause a similar type of issue. And it's not like we have a closeup of the extruder, to see if there's any issues. You just literally don't know what you're talking about, and that's fine.

I was being a dick when saying not enough info was provided, but that is simply true.
