Okay so I’ve had my printer for years and the fucking thing right now is printing like it’s not level. It’s level, I did a visual bed mesh, I’ve done the z offset 900 times, I replaced nozzles, I put a needle up there to make sure no clogs. Running out of ideas here
#Going Insane with printing issues

Ender 3 V2 with zero stock parts
Printed a million things no issues until last week

That looks to me as though it's clogging at the top of the hotend before the filament enters the melt zone?

Yeah that’s what I’m thinking too, going to order more Capricorn tubing and a new hot end because this shit keeps happening

What hot end have you currently got?
What filament is it you are trying to print and what are your bed and hotend temps when attempting to print.
Can you verify if your hotend fan (the one pointing directly at the printer) is in working order and spinning when the printer is ready to print?
I had a very similar issue to this, it started happening after I upgraded my hotend from the creality to the microswiss.
It went from bad to worse when I upgraded to the SKR Mini E3 V3, Mine would print exactly like yours and clog almost instantly, it turned out it was because the fan for the hotend wasn'
t spinning at all, it wasn't spinning because I hadn
t configured it to, once configured it would still happen but about 30 minutes or so into the print
Because the creality hotend has the bowden tube going down into the melt zone, it actually isn
't as susceptible to heat creep in comparison to an all metal hot end, the other side of the story to that was this was happening because I was actually printing inside an enclosure
I was trying to print PLA, once I opened the enclosure up, the print completed, albeit warped as fuck. To fix my heatcreap issues I had to lower my print and hotend temps right down
I was printing at 110c with the bed and 220 for the hotend. I was also getting the filament chewed out at the extruder, after months and months of head scratching I figured out that what was actually happening, the hotend was actually clogging before the filament entered, because the printer is inside an enclosure and PLA is on the verge of being soft as it was, the extruder would then chew the filament out, so because I was seeing the filament being chewed out instead, all the temps where bumped up exacerbating the problem.
Turning the bed down to 60c and the hotend down to 180c (hotend was turned down to 180c because anything higher and the filament started to go a bit stringy netted me my best results
Sorry for the essay. Hope it somewhat helps

Thank you friend
I know exactly what you’re saying
I have the stock hot end
I have the stock hot end
I just ordered a micro swiss
See the burnt tubing?
ornate obsidian
Yup, she's cooked.
Could try trimming that tube down so there's fresh tubing going into the hotend, see if that helps?
Definitely verify that hotend fan is working though, that's almost acting as though it isn't
old spindle
Holy shit you’re a genius
What fan is that and how do I replace it LOL
OK, never mind false alarm. I preheated PLA for a second Which smells like burning plastic, and now that fan is turning

I was going to do that, but this tubing is pretty short already, so I just ordered some new tubing to go with my new hot and

Depending on the firmware your using, it'll already be on
If it's a recently compiled bug fix like mine is, I've noticed mine doesn't switch on until the nozzle starts heating up and it reaches over 55c in temp

That one you where touching is the hotend fan, which is working, the other one with the little cooling duct is the part cooling fan
Report back once you have new tubing and your new hotend installed. Remember because there is no bowden tube inside the melt zone it is a little more susceptible to heat creep. You don'
t appear to be printing inside an enclosure however so I reckon you should be fine

Wait I thought the new hot end should prevent it burning up?

It will, the tube is burning up because it's inside the melt zone, whilst it's rated to 260c your printing almost at the threshold where it starts to breakdown and cause issues
The heatcreep I'm referring to has nothing to do with that tubing burning up. heat creep is referring to a phenomena where the filament starts to get soft before it enters the melt zone
PLA can be a bit of a prick for it as it starts getting soft at 60c, because of this with if the pla filament starts getting soft before it enters the melt zone, it can cause a clog.
Because you are not printing inside an enclosure like I am, you shouldn't have any issues with this, and as long as you stick to the recommended bed temps, you should be fine as well

It’s still fucked

Does this look like it’s working right?
