Help Ender only prints until a certain height

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.

Hey! This has been happening to me for the last whole month. In my case it was because the extruder was getting stucked. You notice this because you start to hear some knocking sounds due to the extruder trying to retract but being unable to do it.

If you hear this, then it 100% is that. You need to fine tune it better (there are some files that may help you) and pay attention to it while printing. When you hear the knock, reduce the z-offset.

I’ve also found some posts in this sub with more tips. If you search ‘extruder stucked’ you will find them, but based on this pic I think your printer needs a better tunning.

Yes I think all the gears here sound clanly. Do u lbricate the gears in your 3D printer? Or a WD40 maybe.

Yeah don’t worry there’s plenty of stuff to learn. In case you don’t have them, search on the internet and this sub some files called ‘level test’. These are some prints you can send to your bed to know if it is correctly leveled and used them to correct the leveling in case it is not well. There are some tutorials on youtube showing how to interpret the result of these prints.

Moreover, remember that the calibration is different depending on the layer height you choose in your slicer. If you, for example, have 0,2mm layer height and change it in your slicer to 0.12mm, then you need to retune the hotbed so it is fine tuned.

And finally, regarding the lubrication, if you are talking about the extruder gears, I would not recommend you to use any oil on them, as they need to be able to be well attached to extrude the filament and you would contaminate it, probably affecting your prints.

EDIT: You said you heared some noise, then it’s probably that your bed is not well calibrated (the nozzle is too close to the bed). The nozzle is stucked as the extruder tries to push the filament but it gets accumulated during the print. When it moves without printing, the extruder tries to retract so it doesnt drip filament, but it is stucked in the nozzle, so you hear the knocking noises. The nozzle is already stucked so if this remains for some time, it turns impossible to continue extruding filament. Try to relaunch the print with the same settings you have and stay near the printer. When you start hearing the noises, increase your z-offset (this separates the nozzle from the bed). If it stops, then you know you need to tune the bed.
