r/Ender3V3KE

Why has this happened on 2 different models. Same problem. I replaced the nozzle and then tried to print two different items. And this is what's happening.

I'm quite new in 3D printing i don't know much on how to tend to the hardware and all and since i'm very afraid of screwing with thing i'm looking for some help on the bed leveling, i did tighten some screw that were quite loose but just a little bit.

Hi all, recently got a KE as my first 3D printer. Is this rattling sound normal or is it a sign of something being loose?

Tudo começou quando eu resolvi trocar o bico original da minha ender 3 v3 ke por um de 0.2mm, acabou que ficou frouxo e vazou no hotend inteiro, comprei um hotend do tipo unicornio/troca rapida, coloquei novamente o bico 0.2mm e intupiu novamente, perdi o hotend porque nesse caso fui burro e nao apertei corretamente, comprei o segundo hotend unicornio, nao troquei o bico 0.4mm padrão, instalei o bico sem modificar nada nele na minha impressora, porem literalmente toda impressão começa a fazer do nada um tec tec tec, entupimento parcial ate onde eu entendi, porem quando eu cancelo a impressão e faço uma extrusao o filamento desce normal, estava fazendo uma impressão de 26 horas, ja tinha se passado umas 12 horas, quando eu tava em casa fazia uns 2 tec tec e parava, não era continuo (primeiro sinal que ignorei pq sou burro), ja consumiu uns 150g de filamento, cheguei em casa agora e o bico estava entupido, a extrusora se movimentando normal porem o hotend não estava puxando filamento, tinha parado de soltar filamento fazia varias camadas e estava imprimindo no ar sem soltar filamento, perdi a peça inteira, tempo e dinheiro, como posso corrigir isso de uma vez por todas? literalmente faz umas 10 peças que ocorre isso, algumas imprime normal, acredito por pura sorte, nao sei mais oque fazer no fatiador, reeinstalei o creality print que uso e imprimi essa ultima peça que falei com o preset de fabrica, foto do filamento como fica quando entope e uma impressão anterior falhada pelo tec tec.

Man, it seems impossible to get a good first layer on this printer.

What could be causing this? I've already tried various things I found on forums and in videos.

I aligned the X-axis. I tightened both belts (without making them overly tight). I tightened some screws while leaving others with a bit of play.

I added Z-axis supports to make the structure more rigid.

I'm using linear rails, which made the Y-axis and the bed very stable and free of wobble. I swapped the nozzle for a "Unicorn" nozzle.

I tested two different build plates: the original one and a PEI plate. Before starting the auto-leveling process on either plate, I heated the bed to 70°C for 10 minutes and ran the auto-leveling (photo attached). I did something similar for the nozzle (240°C for 10 minutes).

During printing, I kept adjusting the Z-offset because it was too high. If I raise the Z-offset, the ridges diminish (though they don't disappear completely), but on the other hand, gaps appear in the first layer along the Y-axis.

I don't know what else to try. It seems impossible.

Should my main board fan be off?

Hey guys. I've got this one and I didn't understand if it's only one piece or a set that I can change the nozzle if I want to. The idea is use a 0.2mm unicorn nozzle some times, since the one that came in this hotend is a 0.4mm.

Hey guys and girls...

I used to have my printer set up in the house, but I moved it into the garage and it's a bit cold and drafty. I've never experienced warping this bad before, I feel like a raft wouldn't have helped.

Is this likely to have been solely caused by the draftiness or are there other issues that make an object warp? Would an enclosure solve this?

20% infill

No raft

No supports

5 hour print started at midnight... So it was pretty cold outside

What is the cheapest enclosure option? I was thinking of a small grow tent?

My ender 3 v3 ke has this bed mesh. It didn't used to matter.

It was fine until a few days ago. The z offset was off by about 0.04mm and I would lower it and the first layer was absolutely perfect. But then it just wasn't.

Now parts of the first layer are perfect and other parts have gaps in them. I cant lower the z offset anymore or it will squish the good parts.

No matter what I do it just does not seem to compensate for it.

I've fixed the gantry(it was of by about 1.5mm).

Does anyone know just what is going on ? I didn't change anything from stock, why did the printer change like this with no reason ?

Hey guys.

I need some advice.

I don't know what I'm doing wrong. Sometimes my print come out very well like the first and second picture.

But then other times they come out warped, wavy and inconsistent like the third picture.

What am I doing wrong? Any way to make the printer more consistent?

My Ender 3v3 Ke is not extruding, idk what happened, I changed the filament and it stopped working out of nowhere...

Any ideas?

I've tried to unclog but it doesn't works...

I read that I should open the extruder.. but I'm not sure even how to do it

I'm making this boxes and everytime I print one, they come with these details and I don't really know why and how to fix them, any help?
