sv06 keeps shredding filament | 3D Printing | Page 1

As the title says my filament just keeps getting shred as if tenstion was messed up but tension really doesnt seem to matter. I tested 12 different tension settings 2 times for each of my 8 spools of filament and every last print failed. 2 spools are one year old polymaker PETG, one is 1.5 year old formfutura PETG, 5 others are 2.5 year old 3djake ecopla. All of them have been in the over at 50C for at least 6 hours. FF and one polymaker sat for 8, one 3djake for 10h. I am completely out of ideas. I don't even know if the filament is at fault or the toolhead magically killed itself. Open for anything at this point because I'm loosing my mind

AI Help

It sounds like you have already tried adjusting the tension settings on your printer with no success. Since the issue is occurring with multiple spools of different ages and types of filament, it's unlikely that the problem lies solely with the filament itself.

Given the extensive troubleshooting you have already done, it may be worth checking other possible factors that could be causing the shredding issue. Some possibilities to consider include:

Nozzle clogging: Make sure the nozzle is clean and clear of any debris that could be causing the filament to shred.
Filament path obstruction: Check for any obstructions or misalignments in the filament path that could be causing the filament to shred.
Heat settings: Ensure that the heat settings for both the hotend and heated bed are correct for the filament being used.
Extruder calibration: Check that the extruder steps per mm are calibrated correctly to ensure proper filament feeding.

If you have exhausted all options...

u know what

#

this sounds like a clogged nozzle

#

or partially clogged one

keen crypt Aug 10, 2024, 10:05 PM

#

nozzle is brand new and cold pull came out clean, path seems fine. the cog was a little dirty but i cleaned it up.its hot enough and esteps are right

#

@crude ferry sadly not

crude ferry Aug 10, 2024, 10:05 PM

#

so how does it shred it

#

how does the print look

keen crypt Aug 10, 2024, 10:05 PM

#

i bought new nozzles because i thought it might be that

crude ferry Aug 10, 2024, 10:06 PM

#

does it squirt plastic"?

keen crypt Aug 10, 2024, 10:06 PM

#

no, it gets stuck cause it cant grip it anymore

crude ferry Aug 10, 2024, 10:06 PM

#

worn down gears?

keen crypt Aug 10, 2024, 10:06 PM

#

crude ferry Aug 10, 2024, 10:06 PM

#

it must be clog, no clean or worn gears

#

unless ur tension is off

keen crypt Aug 10, 2024, 10:07 PM

#

crude ferry worn down gears?

looks fine to my eye, but i'd need a new one next to me to tell if thats actually a thing

crude ferry Aug 10, 2024, 10:07 PM

#

well ok

#

about tension

#

when u run filament through

#

and then get it out

keen crypt Aug 10, 2024, 10:07 PM

#

crude ferry unless ur tension is off

shame i tried anywhere from 1-4 turns of the knob which results in completely different tension strength

crude ferry Aug 10, 2024, 10:07 PM

#

are there teeth mark left on filament

#

or is it just perfectly round with no marks

keen crypt Aug 10, 2024, 10:08 PM

#

crude ferry are there teeth mark left on filament

i tried tension from anywhere between no marks to severely chewed up after one go

crude ferry Aug 10, 2024, 10:08 PM

#

maybe a clog somewhere above the nozzle

keen crypt Aug 10, 2024, 10:08 PM

#

thats why im completely stumped on this

crude ferry Aug 10, 2024, 10:08 PM

#

also possible

#

but if u say cold pull fine

#

then idk

keen crypt Aug 10, 2024, 10:08 PM

#

crude ferry maybe a clog somewhere above the nozzle

so i gotta take the toolhead apart?

#

man fuck this cant someone just make 500€ spawn in my bank account so i can get a q1

sweet girder Aug 10, 2024, 10:10 PM

#

well if it ain't the extruder, ain't the nozzle, ain't the tension on the filament grub screw, then maybe there is a clog in the heat block ?

crude ferry Aug 10, 2024, 10:10 PM

#

i mean if u can cold pull no clog

#

but then only other solution is worn gear

sweet girder Aug 10, 2024, 10:11 PM

#

unless the filament is genuinely just bad

keen crypt Aug 10, 2024, 10:11 PM

#

crude ferry but then only other solution is worn gear

But I really haven't printed much

#

That's what I find odd

crude ferry Aug 10, 2024, 10:11 PM

#

sweet girder well if it ain't the extruder, ain't the nozzle, ain't the tension on the filame...

but he said cold pull clean

sweet girder Aug 10, 2024, 10:11 PM

#

do you have any filament that's not >1 year old

keen crypt Aug 10, 2024, 10:11 PM

#

Maybe 2 or 3 kg passed through that toolhead

crude ferry Aug 10, 2024, 10:11 PM

#

wouldnt be a clean pull if theres a clog above

#

oh btw

keen crypt Aug 10, 2024, 10:12 PM

#

sweet girder do you have any filament that's not >1 year old

I dont, but that shouldn't be an issue since they were stored isolated with plenty of silica that was dried once when it was full and the filament sat in the oven for so long

crude ferry Aug 10, 2024, 10:12 PM

#

when u cold pull

#

do u cut away like 4 cm

#

and put it in again?

#

cause if u just shove it rright in, the clog stays in

keen crypt Aug 10, 2024, 10:12 PM

#

crude ferry and put it in again?

Yeah

Polymaker and Formfutura are supposed to be high quality so a year with very low ambient moisture and good drying shouldn't be any problem at all

#

I might buy new filament but I want to rule everything else out

#

Cause I have so much left

well, we gotta go through pretty much everything to find the fault, and with those checks out of the way, i can't say it's the machine unless you fully disassemble the extruder to see the innards condition

i mean it for sure wouldnt shred

Grinds it down

sweet girder Aug 10, 2024, 10:15 PM

#

oh thats' it?

crude ferry Aug 10, 2024, 10:15 PM

#

this look like worn gears

sweet girder Aug 10, 2024, 10:15 PM

#

time to open the extrudre

crude ferry Aug 10, 2024, 10:15 PM

#

doesnt grip, just rolls on filament

#

or also

#

even if gears are good

keen crypt Aug 10, 2024, 10:15 PM

#

sweet girder oh thats' it?

Enough to get it stuck completely

crude ferry Aug 10, 2024, 10:15 PM

#

could be the gaps

#

just filled with plastic

#

and it doesnt grip

sweet girder Aug 10, 2024, 10:16 PM

#

either way, gotta take off the extruder and disassemble it to see the gears

crude ferry Aug 10, 2024, 10:16 PM

#

it doesnt get stuck

#

its just gears are rounded or full of plastic

#

so it grinds it until it cant grip, and then its stuck

#

just open the head and look at the gears

keen crypt Aug 10, 2024, 10:16 PM

#

crude ferry could be the gaps

I tried cleaning those and they looked fairly good to me but imma get if completely tomorrow morning

#

I do remember that there still is some gunk

well i cant tell u if its good or not without seeing it

No clue if mentioned but check if your feeder gears are still attached to the shafts and the grub screw sits tight

Sorry but what's a grub screw?

crude ferry Aug 10, 2024, 10:20 PM

#

ok yeah

#

this look like needing cleaning

#

but also maybe brand new gear

#

better to get reinforced one

if it exists

unreal sierra Aug 10, 2024, 10:21 PM

keen crypt Its worse than I remembered

crude ferry Aug 10, 2024, 10:21 PM

and also

#

u need to clean both the gears

#

not just the one u can move away

unreal sierra Aug 10, 2024, 10:21 PM

#

A grub screw is supposed to sit in there and secure the gear

Where the fuck could it have gone💀💀💀

look if they are on the other one

crude ferry Aug 10, 2024, 10:23 PM

u need to clean or replace gears

these also just look like awful gears

no yeah i get it

its just idk why u need one

on the motor shaft?

keen crypt Aug 10, 2024, 10:28 PM

crude ferry these also just look like awful gears

Thank sovol ig

#

But I will clean them again

keen crypt Aug 10, 2024, 10:28 PM

#

crude ferry its just idk why u need one

I think you're not supposed to have one there and he just got things mixed up

crude ferry Aug 10, 2024, 10:38 PM

#

keen crypt But I will clean them again

i suggest getting new

#

or clean them really well

#

and increase tension

#

just doesnt seem like these gears have good bite

#

without decent pressure

unreal sierra Aug 10, 2024, 11:05 PM

#

crude ferry on the motor shaft?

To fix the gear to the motor shaft so it actually spins when the motor turns and feeds the filament

it might be fixed now, gonna try an overnight print but tests seemed promising

#

took apart the toolhead and properly cleaned it all

#

most of the tiny plastic pieces stuck in there came from one shitty spool that i could never get to print properly
