- In this video, join me on my 3D printing journey as I tackle unexpected challenges and share my experience with printer repairs and upgrades. Discover how I overcome extruder issues and work towards improving the efficiency of my 3D printing setup while showcasing some exciting projects along the way!
Hey, so that upgraded hotend you got looks very similar to an E3D (That looks like a Pheatus?). Anyways, I have had that issue a bunch and (pardon if you know this already) but ensure that your nozzle is flush with your heatbreak within the melt zone. What has happened to me in the past with this issue is that the nozzle and the heatbreak are not making proper contact, causing filament to expand into the spaces.
Because the heatbreak is not constrained by the nozzle, there is wiggle room caused by the tolerances which cause said melted plastic to ooze up and then out the top of the heatblock.
You can salvage all of those parts with a heatgun or blowtorch. Connect the hotend back up to a board and heat it up. Then remove as much gunk as you can.
Once it is hot, try remove the heater cartridge and thermistor.
Then go to town with a heatgun or blowtorch and use a wirebrush to get rid of the rest of the plastic.
Finally, strip it down, clean it real good inside and time to reassemble.
Put the electronics back and heat it up again.
Tighten your nozzle all the way down, then back off by about half a turn. Then screw in the heatbreak (without the fins) until it is tight. Then tighten the nozzle down. There should be around a 0.5mm gap between the nozzle and the heatblock when it is tight.
You should be good to go again :)
Sorry if this is long-winded or if you knew this already. I have just had that exact issue a good few times and it's taken a while to learn exactly how to tighten everything down properly.

oh yea, a gap definitely caused that issue and luckily the stock ender 3 hotend has been holding up ever since. I did make the bowden tube substantially longer from what the other hotend (creality spider 3.0) was using and all has been good. no leaks or anything. Just for a sanity check too, I checked my other printer and actually replaced the bowden on it as well as it was starting to have little clog issues here and there but since replacing it, all has been good. Thanks for the info!
