Has anyone else purchased this heating block kit?

It comes with a package of thermal grease but no information whatsoever on where, how, or when to apply it. I've checked their tutorial videos, chatted with their ai support, and talked with a human customer support person and have not gotten any applicable information on how to apply it or if I even need to apply it.

Normally, I would just install the kit and ignore the grease. That's actually what I did two months ago when I originally bought the kit. After that kit was destroyed by melted filament, Amazon support had me order the kit again. So now to potentially avoid the same issue, I'm going out of my way to find as much information as I can about this phantom thermal grease.

Creality Official Ender 3 V3 SE/3 V3 KE Upgrade Hotend Kit, with Quick-swap Nozzle Kit, Supports 300°C High Temperature, 600mm/s High-Speed Printing, Ceramic Heating Block for Ender 3 V3 SE KE

Any thoughts?

I recently got an ender 3v se second hand because it has issues I’m trying to diagnose it, but I’m new to 3d printing in general
It starts up tries to set up and just keeps going and gets stuck

SOLVED!
Users u/Wivi2013 and u/maybeiamspicy were able to help me solve the problem. The answer is that I did not install the PTFE tube when I changed the hot end assembly. Thank you guys!

Original Post:

Hello r/Ender3V3SE ! I am having a bit of a weird issue that I haven't seen before on this model - neither online nor in person, and was curious if anyone has had a similar problem and knows how to fix it. Essentially, after a few problems with my original hot end and a replacement stock hot end, I upgraded to the (wait for it) Upgraded Creality Ender 3 V3 SE hot end. After this, everything seemed to be smooth sailing and my issue appeared to be resolved, however, after a few minutes of printing perfectly, extrusion stops and when I open up the head, I find the filament twisted like this inside.

The Issue:
Filament is twisting between the extruder and the hot end.

A Little More Background:
Recently, after a month of having absolutely zero issues at all with my printer (everything 100% stock), I started having issues with under-extrusion and nozzle clogging. I am not one to over-tinker, so once I tried basic troubleshooting (unclogging nozzle, changing nozzle, changing settings, etc), I just replaced the hot end with another one from Creality. The new hot end never worked and wasn't able to extrude anything regardless of temperature (at this point, I have not messed with any of the other settings in my slicer, since I have printed hundreds of objects with no issues).

A little frustrated at this point, I decided to just go for the upgrade instead of messing around with what appeared to be a defective part. After installation, I started a test print, everything looked 100% good when it suddenly just stopped printing after about a quarter inch (height). I figured this might be an issue with my filament and switched the ABS to PETG, slightly changed settings and had the same result. On both, the filament eventually twisted up between the extruder and hot end assembly. I have run into almost every issue you can imagine and am generally pretty handy, but I have no idea why this is happening here.

My idea for What to Do Next:
I have already purchased a replacement extruder, assuming that the issue might be coming from there? However, if anyone has any ideas or has seen this before, I would be very happy to hear it.

Settings:
Filament: I tried a generic PETG and a generic ABS with the same results
Nozzle Temperature: 245 (first layer); 235 for others
Printing Speed: All Settings Under 15mm/s (yes, I print very slow)
Slicer: Creality Print

Specs:
New Hot End: Ender 3 V3 SE Official Hot End Upgrade
*Everything else is stock

If more details are needed for slicer settings to diagnose this, I would be more than happy to provide them, however, as I mentioned above, I had my slicer fine-tuned and printed hundreds of things before this issue - which is why I am inclined to believe that it is a hardware problem and not necessarily software. But I'm open to anything at this point!

I already tried changing SD, and using other slicers. The thing is that sometimes it prints fine and sometimes it does this

Goodnight! Not long ago, I wrote about a malfunction when the nozzle of my printer was losing support and the print quality was terrible. I found a solution. Maybe it will help someone. I decided to check the belt tension. I downloaded a guitar tuner and adjusted the Z‑axis belt. Its frequency was 103 Hz. I did the same with the bed belt — it was 80 Hz. Using an Allen key, I increased the belt tension to 107 Hz, and the printer started working as it did before!

Hey guys, after a bit of effort I managed to install the Navaismo firmware and it looked like it was going to be smooth sailing but my flow rate tests have been going badly. I already calibrated the e-steps, the PID's, the bed points with the Z-offset with the sheet of paper and the temperature of the filament but idk what else can I try for this

I’ve noticed this problem happens mid print after a certain height is reached I’ve also noticed weird. I’ve got no clue as to why this is happening; anyone knows what causes this?

I've found this hotend kit called "Creality Ender 3 v3 SE hotend kit" and it says it heats up faster and up to 260c. Do any of you know about this kit? I can't find any other kits available where I live so this is my only choice, I was wondering if its worth it and an easy swap or does it need mods? There is also a cheaper choice without the heatsink.

Every time I print a part with a smooth curve like the one in the picture using CooBeen filament, there is a raised line or two in a random spot. However, when I use eSUN filament, this does not happen.

Do you have any ideas?

First layer, in an enclosure. It just strings constantly now what do I do?
