Im having issues with hard to remove/messy supports (its a stringing issue apparently, still unsolv)

[flat lava]

I tried to print a model I found online and followed a supports settings profile from a ytube video (ultimaker cura) but the supports ended up as just a mess over the model. I had printed the same model before but at .1mm and it came out better than this .06mm one (I also made it smaller). Im using an Entina Tina 2 printer

AI Help

It sounds like the issue could be related to the layer height and the support settings for your specific printer. When decreasing layer height, it's important to adjust support settings accordingly to ensure proper adhesion and structure. I recommend experimenting with different support settings, such as support density, pattern, and angle, especially when printing at smaller layer heights like 0.06mm. Additionally, checking the support interface layers can also help improve the quality of the supports. Feel free to reach out if you need more specific help adjusting your support settings for your Entina Tina 2 printer.

The material is just some random pla I bought and 210c

The one at .1 mm also had alot of issues but mainly from the back

Its also really hard to remove the base brim

[flat lava]

The supports also really just dont look like the ones in the preview

But that might just be me

[flat lava]

this is me trying a third time but at .1

to see if it makes it better

and so far it aint lookin good

[spark urchin]

That honestly might be part of your issue

[flat lava]

the material or the heat?

lemme check the brand rq

[spark urchin]

The material

I genreally try to stay way from random PLA's etc

But if you're stuck with this one, I think the issue you are epxerienceing are support marks

[flat lava]

its anycubic printer filament

1.75mm

[spark urchin]

Not random then

[flat lava]

well its the cheapest I found and idrk many brands

[spark urchin]

Ok, so I would see what rotation Cura recomends

[flat lava]

rotation?

[spark urchin]

Orientation

Right now you printed on the back

I think you might be fine printing on the feet if you enable brim

[flat lava]

how do I see what cura recommends

[spark urchin]

Go to their market place

Type up auto orient

Install that, then I think you right click on your model and press auto orient? Idk

[flat lava]

this?

[spark urchin]

Yes

[flat lava]

aight lemme make an account

[spark urchin]

Ok

(btw you can just swap to orca slicer you know)

[flat lava]

that another software?

[spark urchin]

Yes it is

If you want to try it do NOT install from https://orcaslicer.net/; it's not official and might be a hack

Use Github instead

[flat lava]

I dont see an option to auto orient

op nvm

this apparently

[spark urchin]

Fascinating

[flat lava]

anything I should change for settings?

[spark urchin]

Ok, I'm not an expert in supports; I never tried mofifing them. So what I'll say right now is to put it on the feet, turn the brim on and hope for the best (that oreitntation minimizes support contact)

Orca has good supports though

[flat lava]

place the supports manually?

this is what I get when I slice

line supports is what I selected

the thing is, this isnt what the printer prints

it feels like it just does whatev it wants

the 3rd one im doin is almost finished, Ill send a pic of the arrangement when its done

[flat lava]

Almost as if it were trailing material

the arm literally just fell off

maybe it really is just an issue with speeds but idk what to do to fix it

[nocturne yacht]

This looks like more than just a support issue.

You have stringing almost everywhere.

[nocturne yacht]

What's the filament's recommend temperature?

You might printing too slow or too hot.

[flat lava]

at 50 to 150 mm/s its 190 to 210

im printing at 210 I think and the speed default was 100

[nocturne yacht]

Put that to 150 mm/s

Or lower temperature to match the speed.

[flat lava]

I cant find a temp option in cura

[nocturne yacht]

It should be there...

I don't use cura, but the last time I used it, it was there.

[flat lava]

below support its just dual extrusion and build plate adhesion

[nocturne yacht]

How about quality?

[flat lava]

That just has layer height

oh found it

it was printing at 200

it was under material

so you think 150 200 will work better?

[nocturne yacht]

Hmmm
.. I would say yes... but try this stringing test first.

https://www.thingiverse.com/thing:2080224

[flat lava]

ok

[nocturne yacht]

It's so that you don't waste much filament all while getting answer.

[flat lava]

fair

I think ive alr used like a 3rd of 1kg

[flat lava]

do I just print it like this?

[nocturne yacht]

Yeap

[flat lava]

aight, cya in 40 minutes then

[flat lava]

so

it hasnt been the minutes yet

but its def stringing between the pillars

[nocturne yacht]

Can I see how much?

[flat lava]

one sec

I think ik why

When I checked the printer it said speed was 100

When it shoulda been 150

I manually set it to 150 rn

Ill see if it improves

Better picture

[nocturne yacht]

Stop the printer if you suddently hear clicking noises FROM the printer. The clicking noise might be the extruder being too quick.

[flat lava]

Its not clicking

And it hasnt made any weird noises

That said, yikes I think the filament is kinda a knot

So ima pause it for a few mins see if I can untangle it

[flat lava]

This doesnt look like just stringing tho

This looks like something the printer is doing delibaretly no?

And very much not what the slicer previews

[nocturne yacht]

It looks like this

What I also recommend is to also try to mess with retraction settings.

Try 5mm height retraction and 25mm/s retraction speed.

[flat lava]

This what its supposed to look like?

[nocturne yacht]

It's not

[flat lava]

And you think the height retraction settings can help?

[nocturne yacht]

Yes

As well as retraction speed

[flat lava]

Then ima stop print and try that

[nocturne yacht]

Sure

Idealy you want it to be like the right one

[flat lava]

I cant find just retraction height

And idk if rectraction priming speed is important

Is it perhaps this?

Theres also retraction distance

@nocturne yacht ?

[nocturne yacht]

That should be the same thing

[flat lava]

Default was 35 mm/s btw

For retraction speed

[nocturne yacht]

No wait

Retraction distance

[flat lava]

Retraction distance is the same thing right?

[nocturne yacht]

No the z hop

[flat lava]

The z hop is the same thing as height?

[nocturne yacht]

Look at both description.

I'm not ganiliar with z hop.

Familiar*

[flat lava]

Thing is idk what you mean by retraction height

[nocturne yacht]

As in once it's done printing the area to the next area. Your nozzle would get higher as a way to prevent stringing.

[flat lava]

Then its prob z hopping right?

Z hop speed default is 10 mm/s

[nocturne yacht]

It's said when the retraction is done.

[flat lava]

1mm height

Doesnt it retract between extrusion?

[nocturne yacht]

I wouldn't mess with it if most people are not paying much attention to it and mostly blaming retraction speed and height.

[flat lava]

But idk what height setting I should change

And z hopping in general is off by default in cura

Atleast the when retracted

Theres these settings

Im just gonna set both speeds at 25mm/s and toggle z hop since it seems a preventative measure, see how it goes

Oh btw when u said the 150mm/s

[nocturne yacht]

Wait, they were both off by default?

[flat lava]

Is that nozzle speed or just the extruder movement speed?

[nocturne yacht]

Extruder movement

[flat lava]

Z hop when retracted was off by default

So nozzle should be at 100?

Because I just realized nozzle was what was being changed according to the printer when I set print speed to 150mm/s in cura

And I assume thats the extrusion rate not the movement speed

Oh wait nvm im dumb, I think that was just temp since it changed by itself

The printer really is just ignoring the 150mm/s

After setting speed to 150

(Manually)

[flat lava]

Its looking even worse and its barely started....

U sure this what u mean by retraction speed?

Is it this complicated on other slicers?

Ima try orca slicer

[flat lava]

Yknow what nvm, printer wont recognize anything from it

Im trying prusa

nvm it doesnt want to recognize anything from that gcode either

this is just so fucked

[spark urchin]

Try Orca

[flat lava]

I alr did

[spark urchin]

Also what do you mean doesn't want to recognize? Is the file not appearing in the file list?

[flat lava]

I selected marlin generic as that is what the tina2 uses apparently

[spark urchin]

Huh

[flat lava]

it does but its as if it was a blank file

[spark urchin]

Is there a preset for your printer in the slicer

[flat lava]

no

[spark urchin]

Sad

Idk what the issue might be then

[flat lava]

I dont even know if its worth it to try n keep goin

idk what else would be compatible like cura is

I think the printer's sd came with like a proprietary slicer but that thing corrupted itself a bit ago for some reason so I lost the files

Im having issues with hard to remove/messy supports (its a stringing issue apparently, still unsolv)

Another fail...

And none of my stringing tests on any of the settings worked well either

[flat lava]

Another test at .12 layer height

Still stringing

[nocturne yacht]

How old is your filament?

And what's your extrusion speed, retraction speed, retraction height, print speed or travel speed?

All of these settings
