And which filament?

[stray acorn]

Pla

[stray acorn]

I downloaded a plug in on cura for a retraction test sliced it like normal but can’t print it as it comes of my build plate after 12 ish minutes of printing

[bright sierra]

Try 220c and 65c bed

[stray acorn]

Thought increased temp would make sticking worse

[bright sierra]

Yes no

Too cold molecules dont separate

Too hot water evaporates or the material decomposes

Also its the easiest to test other then like chech hotend assembly, thr gcode preview etc

And since the n3 is quite fast to cold is often the reason

[stray acorn]

Should re do my helmet print and see if that works or something else?

[bright sierra]

Maybe make a stringing test first

[stray acorn]

Ok is it alright if I keep this up untill tomorrow and message you back it’s late for me and have to head off

[bright sierra]

Good night

[stray acorn]

Night

[stray acorn]

Went to try my stringing test and it came of the build plate and the brim is messed up

I haven’t done anything to my printer since downloading a plugging to get a bunch of tests it’s called autotower since then my brim won’t print right

The only other thing I can thing of that would ruin the br is that I looked and clicked on the other ones like skirt raft but changed it back

I’m so confused

[bright sierra]

Hmm i have a idea. Can you post the gcode you used please?

@stray acorn

[stray acorn]

How do I find that?

[bright sierra]

Joke aside. Usally thats the file your slicer creates and you send to your printer. Like stringingtower_50min.gcode or so

You can send the stl too if you want but the gcode is more important because i can read it and see if something is missing

[stray acorn]

thats the file

@bright sierra

[bright sierra]

That not looking too bad 🙂

It seems you did not set a z offset

You can also try going into your slicer and uncomment the m420 command by removing the ; at the beginning. (I would also remove the Z10 with it because z fade is annoying)

[stray acorn]

im confused
it was running fine and now its not and i have to change code

[bright sierra]

You might have had been lucky that everything was level enough so you did not need it

You can double check all the mechanics screw and wash the bed with water and soap too

Printers get weird over time. Lagerones like to tillt the x axis from time to time for example

[stray acorn]

ahh ok so how do i change the gcode

also with changing the g code do i have to do everytime with a print i want to do or not?

[stray acorn]

IVE FIX THE BRIM ISSUES THE FILE WAS CORRUPED IN A WAY

running the stringing test

[bright sierra]

Great

And you change the start script in your slicer

[stray acorn]

No I didn’t do that as I’m not sure how too

Forgot to double check the temp but
Temp was 210 nozzle and 65 bed temp

Brim came out a bit bad but that because I may have move a dial or two on the bed level

[bright sierra]

I think the pla is moist and you need to dry it

[stray acorn]

When I first started the print it was fresh had a few failures but once i got it going it was day 3 of it being out

[bright sierra]

Filament absorbs moisture over time or is mostly moist out of the box due water cooling while productio

[stray acorn]

Drag roll of filament and at 220 nozzle temp still with string

[bright sierra]

Hmm do check your hot end if there is a leak 🙂 if not check your retraction values

[stray acorn]

how do i check retraction values

it did leak a little bit after the print was finshed so imma bring the temp down

[bright sierra]

I mean leaking between block and nozzle or heatbreak not oozing

The retraction values are in your slicer too

[stray acorn]

any suggestions on what i should put it at

[bright sierra]

What do you have

[bright sierra]

Id try 1.5mm and a speed of 35

[stray acorn]

running a test now for it

[stray acorn]

It’s still happening

220 nozzle

And the settings you set

just testing the retract spped at 50

[bright sierra]

50 mms speed or distance?

Because distance is 2 to 3 mm tops otherwisr you end up with a clog in the heat break

[stray acorn]

It was speed sorry

and it did nothing

should i do 2mm retract in at 35 spped

@bright sierra

or do put it back too 1.5 retract in and 35 spped and turn on combinding mode?

[next tide]

what is the humidity of that filament? I didn't see it anywhere.

[bright sierra]

Id try that

But just as a reminder which printer do you have agsin?

[stray acorn]

elegoo neptune 3 pro

[stray acorn]

it doesn't say anywhere

it still did nothing still having stringing issues

@bright sierra

im not sure if im doing it wrong

i edit the settings then re slince it and thats it

is that right

[next tide]

so what is the humidity of the filament? water retention can cause stringing problems, and the N3 is an open printer, so even when that filament is almost bonedry after a few hours it contains to much moist and should be dried.

if its too dry it might also cause problems.

[stray acorn]

ive done some more digging and found an old reddit(1 year ago) post apperntly an issue with cura and the neptune 3 pro and i have to change the retration in the cura files

still confused

[next tide]

I stopped using cura completely and switched to Orca. I like Orca better, not because cura had problems with my N3 max.

[stray acorn]

this is what i found

[next tide]

as for humidity, check it, even out of the vacuum sealed bag filament might be too moist and moist means stringing etc. It might pay of to get a filament dryer

[stray acorn]

do you recon i should try drying or do what they say in the imaige

[next tide]

i would start drying, and i would switch to orca slicer, prusa slicer or bambu studio they are all from the same origin. you have more people that can help, believe me. ultimaker has made it abundantly clear, that they are absolutely not interested in hobbyists.

[stray acorn]

ill give it a look

do you mind if i contact you if i still have issues as your the only one i know with a n3

??

[next tide]

that's fine, send me friends request, we can talk direct then, sound and/or video.

because typing is hard for me, my left hand is paralized, so speech works better for me.

[stray acorn]

thanks for your help
also sent a rewuest over
just to say im english so imma have to head of for tonight and try one of the other slicers to see if they help

[next tide]

I'm from the netherlands, so i know the drill 🙂

i would go for orca. i'll tell you later why. So Good night for now

[stray acorn]

night imma close this down tommorw i think

[bright sierra]

it is

ohhh do you have z hop on?

[stray acorn]

Not sure should that be off

[bright sierra]

For a test yes

[stray acorn]

I’ll have to test it later

[stray acorn]

still having stringing

turned on advanced any of these help me out

On the right is with out combing mode on and the left is it on does seem to do anything I thing the settings are t saving or something @bright sierra

can it be that fact that its prtining at 0.2 mm
