Filament isn't sticking onto the bed & nozzle keeps hitting the bed even after changing the Z Offset

[spiral compass]

Alright so, I recently installed CR Touch but every single time I start a new print I have to change the Z Offset by a large amount just to make sure it doesn't scratch the bed. I've recently bought this Ender 3 v2, and I'm pretty new to 3d printing so, uh yeah I don't know that much shit.

One other problem is the filament not sticking on the bed, I've used many youtube videos trying figure this out but still none of them worked. I tried cleaning the bed with Isopropyl Achohol and even just Soap and Water... Even so I tried using glue stick or even liquid glue to try to make the filament stick onto the bed, yet it still didn't work.

I have updated all my software, and stuff.. It's pretty new, barely even two months old.

Would really appreciate of someone could help me!

^ this is the picture of the bed

I don't know if the bed has been scratched, maybe thats why it isn't sticking onto the bed

Have you made sure to click “save settings” when you change your offset…?

[knotty geyser]

Did you change the startscript in your slicer?

[knotty geyser]

Because stick slicer start script is wrong

[spiral compass]

I have no idea what that is

[spiral compass]

Where is that located? Maybe that may be the reason

But do you guys have a solution for the filament not sticking on the bed?

[knotty geyser]

https://all3dp.com/2/cura-start-gcode-end-gcode/

[silk gyro]

Whenever you adjust your settings there should be something along the lines of “save settings” and “load settings” at the bottom of the list

[spiral compass]

I thought cura automatically has that?

[knotty geyser]

bahaha

sorry

not in the way you think

the start gcode is applied automaticly correct

but the stuff you need to add to even turn on auto bed level is not

aka the G29 and or M420 S1 command

[spiral compass]

I don't have that for some reason?

Is it in the control section or the prepare section?

[silk gyro]

It should be in your bed leveling tab

[spiral compass]

I have a leveling tab, but it only automatically levels the bed there isn't an option to save it.

[silk gyro]

Ig we have different firmware; I can’t help u then

[wanton kindle]

Is it a glass bed? And if it is are you using glue or hairspray

[spiral compass]

I'm using glue, yeah

All of a sudden when I added the CR touch, it just stop sticking

and plus, the nozzle isn't that far above the bed itself

[wanton kindle]

Are you sure your zoffset it right?

[spiral compass]

I don't know, cause I have to change my z offset every print

but when I print, the filament doesn't stick it

at all

maybe because the fan is on too much?

[wanton kindle]

Ok try this

Extrude 25mm of filament

Tell me if it comes out straight or curls

[spiral compass]

So do I just manually turn the valve or do you want me to print a bed level test line thing??

[wanton kindle]

Just use the move on the screen

[wanton kindle]

U should be able to move it with your screen

[spiral compass]

yeah

[wanton kindle]

Does it curl or come out straight

[spiral compass]

It curls if its bit away from the bed

but if It's properly close the bed

I tried using the z offset

whereas it came out straight

[wanton kindle]

I mean right when I comes out is I straight or curled?

[spiral compass]

do you want me to keep the extruder close or afar from the bed?

[wanton kindle]

Far

Like 100mm at least

[spiral compass]

then yeah it curls

[wanton kindle]

Ok so usually that means there is a clog

Or the nozzle may be damaged

Do you get a lot of stringing?

[spiral compass]

yeah

[wanton kindle]

I would buy a nozzle kit that comes with needles

[spiral compass]

I have one

[wanton kindle]

First try using the needle

So heat it up to 240

And put the needle in the hole

[spiral compass]

one other thing, do you know why it doesn't stick to the bed

I tried cleaning it

[wanton kindle]

When it curls it will have problems sticking

[spiral compass]

do you know any youtube video I can watch?

I have multiple extruders, it came with the package

[harsh harbor]

i keep trying but mine attaches then the rest just does not attach ive leveled the thing about 20 times

may clear the nosel

[wanton kindle]

I don't really do youtube

[spiral compass]

no no, im saying do you recommend any videos?

[wanton kindle]

Another way you can get rid of a clog is heat the nozzle as high as it can go safely and then extrude like 500mm

[spiral compass]

And uh, do you know what bed tramming is?

is the same thing as bed leveling?

[wanton kindle]

I've never done it. I always use the paper trick

[spiral compass]

I always used the paper trick

[wanton kindle]

Same here

[harsh harbor]

i tried the paper trick but still wont work

[wanton kindle]

Then you aren't doing it right

[harsh harbor]

well ive literally done everything possible it was working before but now it aint

unless i basically dismatle the whole thing

when i first put it together i did everything that the thing told me to do

and it worked but half way through my benchy print it came loose and now i cant recongicure it

[wanton kindle]

What came loose?

[harsh harbor]

the print itself

it adheared to the bed but now nothing does as all the settings are off and i cant fix it

[wanton kindle]

Do you have glue or hairspray on the bed?

[harsh harbor]

no

mines a magnetic sheret thet goes ontop of the hot bed

[wanton kindle]

Try glue or hairspray

For glue it's the purple glue sticks

[harsh harbor]

just spray hairspray on it

[wanton kindle]

For hairspray the strongest hold with no oerfume

Yea I usually do 2 layers of hairspray

First I spray one

Then wait and spray another

[harsh harbor]

on the magnetic sheet

[wanton kindle]

It won't hurt to try

[harsh harbor]

true

[wanton kindle]

Usually you don't need it with pei

But it's worth a ahot

Just print something small

And put the glue in that one spot

Do not do the whole bed

[harsh harbor]

ive no glue

took the thing apart, well most of it, reassembled it, sparayed hairspray on sheet, now jkust leveling it

ngl i think the hairspray worked

[wanton kindle]

Ok cool

[harsh harbor]

maybe as part wasnt stuck down so trying again

It’s working

[wanton kindle]

Good

[harsh harbor]

if that wasa the rason gonna do a haul of cheap hairpsray

[wanton kindle]

I use the cheapest I can find in walmart

[spiral compass]

ok

I just replaced my uh

nozzle

and cleaned my hot end

now it works

thanks

I think why some parts of the bed the filament isn't sticking is due to the levelment

thanks @wanton kindle

[wanton kindle]

No problem. Happy to help

[spiral compass]

I think I may of figured it out why it wasn't sticking onto the bed

I need more bed clamps

actually

Im pretty sure normal clips work

[spiral compass]

the normal elmers glue sticks also work

but quick question

is liquid glue fine

?

or it has to be glue sticks?

[wanton kindle]

Has to be sticks

[spiral compass]

alr

[wanton kindle]

The purple glue sticks are best

I like the purple cause I know when it's dry
