Stock ender 3 with 3d printed x and y tensioners, trying to print pla at 200 degrees nozzle and 60 degrees bed, I did fix this issue for a little bit by increasing my retraction distance from 5 to 6 and decreasing the retraction speed to 25-35mm/s, printing at 60mm/s, I also have ultimaker cura 5.3.2 (if that's the latest version)

[grim monolith]

wich pla brand?

[chrome drift]

Ender

(Creality)

It's worked fine before

[grim monolith]

creality PLA?

[chrome drift]

Yes

[twilit comet]

how does your extruder look when this is happening?

[chrome drift]

Where

@grim monolith I cant seem to push this up

And I'm quite low on length of tube

[chrome drift]

@twilit comet

[twilit comet]

the actual extruder motor not the hotend

this guy^

[twilit comet]

you're pushing down on the little white part that inserts into the metal right?

[chrome drift]

Yes

Ita not moving

[twilit comet]

might be easier to get out with it screwed in

the tube isn't moving or the tab isn't moving

[chrome drift]

I dont get why you asked this?

[chrome drift]

The tube

[twilit comet]

could be under-extruding

what does your filament look like after it's been fed through the gears

[twilit comet]

screw the fitting back into the hotend, push down that tab, and give a really solid pull on the tube

brace the top of the gantry with your hand if you need to

[chrome drift]

Better, hot or cold?

[twilit comet]

you could try hot but that's not really part of the hotend that retains heat

it's above the heatbreak

for your original question, this looks like underextrusion to me which is why i'm asking about the extruder motor

also maybe layer shift? is that image of a dimensionally accurate piece?

how tight are your belts?

[chrome drift]

Got it in

[chrome drift]

Bouncy

My 3 cold pulls (im missing the third one)

[twilit comet]

that doesn't really give me any insight so i'll just say that wobble like this is usually belt tension

[chrome drift]

What should the ideal bed tension be

[twilit comet]

reference this photo, the hotend on the right, it looks like you might not be getting your PTFE to your nozzle fully

to my understanding you should be able to pinch it between two fingers with some resistance

tight enough so that your bed doesn't move when the stepper is locked

you want to eliminate any wobbling or vibration in any of the axes

[chrome drift]

I dont understand

[chrome drift]

This prob doesn't help

[twilit comet]

your fingers are the arrows

[twilit comet]

honestly i'm not a physicist or an engineer so i'm not sure

[chrome drift]

The only problem is that I am a engineer

[twilit comet]

if the vibration is being transfered into either your x, y, or z axes, it will affect the print

it's that simple

bed shouldn't move with stepper locked, hotend same, z same

[chrome drift]

I have my belts so that it feels bouncy/springy near the tensioners

[twilit comet]

i don't really have a guide for you past x/y only move when belt moves

tighter generally is better

[chrome drift]

Yeah

When I auto home it and it locks the x y and z I cant move anything

[twilit comet]

that being said i think you can just slap some home depot foam and concrete under the printer to really isolate it

yeah that's standard, it holding home position

you have to hit disable steppers in the menu

to move them by hand

i feel like we're going down the rabbit hole here though

is your ptfe tube out?

[chrome drift]

How much resistance should I get when leveling my 4 corners

[chrome drift]

No its in

[twilit comet]

getting it so you can pull it out/put it back in is probably your first priority here

[chrome drift]

Fair

[twilit comet]

because if your ptfe isn't setup properly it can look like other issues

[chrome drift]

I can now pull my tube in/out easily now

[twilit comet]

if you did your cold pull with the nozzle in, to me it looks like it could be seeping a bit

okay perfect

just took some force right?

[chrome drift]

Yes

[twilit comet]

okay so now you want to eliminate any possible gap between the PTFE tubing and the nozzle itself

[chrome drift]

I took the tube out and stuck some pla in it by hand so it just heated it up faster it could push it out the nozzle

[twilit comet]

oh okay

sounds like the nozzle is clear then

[chrome drift]

I now need to level it

And I never know what " a little resistance" is

Leveling Your Printer
Here is a handy infographic that will help with levelling your printer.

[twilit comet]

next priority should be to install PTFE properly

[chrome drift]

I have

[twilit comet]

did you heat the end, loosen the coupling, feed the PTFE, lock coupling, and then tigthen coupling?

[chrome drift]

Yes

[twilit comet]

okay perfect

for leveling, i have a feeler gauge i use but it's really a thing you dial in

if it's a piece of paper and you picture the nozzel is a pencil, you want to be able to make a thin line

for the ender i recommend tightening your screws all the way and then loosening for your leveling

[chrome drift]

I also noticed is it normal for my infill to look like the layers are not even sticking to each other

[twilit comet]

there's several variables that can affect that

but generally layers should adhere regardless of what function they serve in the print

[chrome drift]

No I mean my infill layers most of them aren't touching eachother apart from the cross sections ( I'm using zig zag)

[twilit comet]

vertically or horizontally

https://www.printables.com/search/models?o=popular&q=ender 3 level

find something here that works for you and adjust your z axis offset as the layer goes down

[chrome drift]

Height

[chrome drift]

Is that the knobs

[chrome drift]

This is what I mean

[twilit comet]

this looks like an extrusion issue

[twilit comet]

no, it's the setting in the menu called z axis offset

[chrome drift]

I can never find it cause I never know it existed

[twilit comet]

how long have you had this machine

[chrome drift]

March 9th

2023

[twilit comet]

have you been using the manual leveling nobs to set your offset this whole time?

i'm just confused because in most instructional videos and manuals i've seen, this functionality is made pretty explicit

level your bed, calibrate your extruder, print a test cube

[cerulean lynx]

http://benchtopmachineshop.blogspot.com/2019/04/printer-belt-tension.html

[chrome drift]

I've done that

Only using knobs

[twilit comet]

yeah don't use the nobs for offset, you just want to use those to make sure the bed is the same height in all four corners

[twilit comet]

so then your extrusion issues are most likely mechanical which i why i asked about your extruder in the first place

[chrome drift]

My extruder seems completely fine it skips once in a while but that's it

[twilit comet]

okay that's not fine

[chrome drift]

It's not cracked

[twilit comet]

it should not be skipping

that is not a function of the extruder

it is a failure

[chrome drift]

What can cause it to skip

[twilit comet]

when it slips, filament is not fed

thus under extrusion

[chrome drift]

Fair

Also do I want z hop enables?

[twilit comet]

generally no

causes stringing

[chrome drift]

Tomorrow can you help me sort out my settings and stuff since for me its 1 am

[twilit comet]

mechanical issues. screw not tight enough, teeth worn down, etc

idk if i can personally but someone else on here will for sure

i will say i never solved my e3v2 neo's extrusion issues, i just got an sv06 and never looked back

i ran into problems literally a month after owning

[chrome drift]

I had this same problem like a week or 2 ago and people just said to get new hot ends and extruders

[twilit comet]

yeah i decided to just get a whole new machine

new extruder will fix the issue for sure

the stock creality extruders are bad

[chrome drift]

Yeah

I'm just kinda saving up for like 3 different things

[twilit comet]

welp if you wanna learn how 3d printers work keep the ender around because it's sure to fail again

[chrome drift]

I know

[twilit comet]

glad i know what i know though!

[chrome drift]

Would loosening the bolt on the extruder make it tighter?

[twilit comet]

oh god

i think so????

you can pull the PTFE out of the extruder side and check how deep the tooth marks are on the filament

[chrome drift]

Wait

Does that bolt even tighted or loosen it at all?

[twilit comet]

that screw controls the tension

[chrome drift]

To?

[twilit comet]

well the spring controls the tension and the screw depresses the spring

the arm

[chrome drift]

That's not what it looks like

[twilit comet]

which holds the spinning wheel that presses the filament into the toothed gear

[chrome drift]

The bolt screws into the thread that keeps the spring in place

[twilit comet]

the piece that is holding the screw is also holding the spinning bearing

this piece, the arm, is tensioned by the spring

[chrome drift]

Yes

But the bolt doesn't control that

[twilit comet]

yes it does.

bolt or screw?

[chrome drift]

This

[twilit comet]

this controls tension

screw in, depress arm, notice difference

?????

[chrome drift]

Nope all I see is the bolt screws into the thread and the thread is only there, free floating because of the spring

And the thread keeps the bold there

[twilit comet]

it's a screw

there's a metric head slot for it

it screws either clockwise or counterclockwise

that is not a thread lmao

it's just to keep the spring around the screw

look at the head of the screw, determine the size of driver/bit needed to turn it, and rotate it it in a direction

squeeze the arm and notice the increase or decrease in force needed

[chrome drift]

So it's either I put it back together wrong or mine don't work

[twilit comet]

make a video

[chrome drift]

Taking it apart and putting it back together

[twilit comet]

you might not need to

[chrome drift]

Why

[twilit comet]

https://youtu.be/5UEUFDP8M30?t=648

click that

it's your extruder

[twilit comet]

yup

that adjusts the tension on your filament

that is the screw i was referencing

and that audible creaking was the tension changing

[chrome drift]

The bolt I was mentioning

No

[twilit comet]

lmao ok

yeah you're right

[chrome drift]

That's the spring trying to kill itself

[twilit comet]

because of tension

it is

too

taught

compressed

whatever you wanna call it

it is adjusting the spring

which controls the tension

this is the function of the spring

[chrome drift]

It moves the spring like 3 millimetres when it's fully tightened

So I'm sure it's not doing it properly

[twilit comet]

okay that is entirely different than telling me that it's not what the function is

i have had experience with this piece of equipment and am explaining to you that the issue is your extruder skipping, which is most likely because of the tension

[chrome drift]

Yes

I know that

U said already

But I don't think my tensioner is working properly

[twilit comet]

print spacers

[chrome drift]

That's the god awful clicking u heard

[chrome drift]

No way

[twilit comet]

when you interchange terminology things get really confusing

[chrome drift]

No I was saying the bolt "screws" into the thread

[chrome drift]

.

[twilit comet]

there isn't a bolt in the extruder

[chrome drift]

😐

So the thing I was turning was not a bolt

Cause it wasn't a screw

[twilit comet]

no you're right you got it figured out

have fun with your printer

[chrome drift]

Bruh

Fine

[twilit comet]

engineers lmao

[chrome drift]

What

Tell me what it is then

If it isn't a bolt

[chrome drift]

Where does the long bolt go then I cant just bend 90 degrees

[twilit comet]

damn didn't know the e3 extruder had bolts

is that a knockoff or something

i know there's a screw that adjusts tension

since screws go into threaded parts, like the arm

and bolts affix non threaded parts with a nut

but y'know i'm not an engineer just some dummy who had this exact problem

[chrome drift]

Cool

[twilit comet]

duhhh can you hear my knuckles dragging on the keyboard as i type this

my brain is having a hard time comprehending your issue oh nooo

what is a screw and what is a bolt i just don't get it

[chrome drift]

Well I'm sorry that my tensioner isn't working like everyone elses

[chrome drift]

:/

[twilit comet]

i've spent over two hours on your problem when i had it figured out from the jump dude

i'm not your 3d printing sherpa

watch some youtube videos and learn how your thing works ffs

ignorance is one thing but please don't try to educate me on something you're not understanding yourself

[chrome drift]

That I know that a bolt screws into something?

Ok

[twilit comet]

screw goes into threads, bolt goes into no threads

arm has threads

[chrome drift]

A nut has threads...

[twilit comet]

GOES INTO

good reading skills huh

[chrome drift]

👍

[twilit comet]

get a refund from whatever school you paid too much for bud https://monroeengineering.com/blog/bolts-vs-screws-whats-the-difference/

[chrome drift]

Paid into non thanks very much

And u could of just sent that the first time?

[twilit comet]

i did

you're just dense

@twilit comet if you can't be civil, then don't engage here.
