Surface binding to walls / holes on surface

I m printing some terrain model on my P1S and I face some issues with little holes appearing. So far I have tried:

  • ironing surfaces
  • increase numbers of walls
  • use arachne setting
  • tried different infill patterns
  • tried some different top surface patterns
  • tried different presets for quality (standard 0.2, draft 0.24, better quality 0.16)

I also ran a calibration but I am starting to be out of ideas (and filament :wink: )
What seems to work best is to increase the number of walls and having concentric top surfaces but I still face some issues at the junctions between flat surface and walls. Anyone has some ideas how to solve it?

How many walls and what infill percentage are you printing this at? How many top layers?

I have 2 walls, 15% infill, topshell layer is set to default 5.
I am running one atm with 3 walls to see the effect and was thinking to compare with 2walls/20%infill, but I am just trying my luck.

for testing just use the slicer to chop around the area and only print multiple sections of that to not waste filament and time. (doesn’t need to be tall either…just 1/2 a cm to get the top surface cut all the rest away)

Also once done clone the chunk, per-object setting and change each top layer yada yada to get them all done in 1 go and compare side by side on the same plate.

oh good hint @Unique_Letterhead ! I only tried global settings and started to get lost in what I actually changed. I’ll upgrade my slicer skills tonight :star_struck:

I actually dreamed yesterday of a feature to print the some settings of each object on the side or underside of it.

Sorry typing fast, but yes I meant use the ā€œcutā€ tool to just whack off 3 times the extra you don’t care about, and the bit that is broken.

Then fill the plate with 3-4-5 copies, hit the per-object and tweak away. Keep one default slicer like 02 layer height or whatever if you can - then all your changes. At times the machines calibrated and knows better than some of our rabbit hole deep dives.

Let us know, snap a pic of the plate so we can see them too and compare maybe

Here are the results with 3 walls. Less holes but the walls boundaries are more visible :confused:

running 11 copies atm. Ran out of filament so it will be bicolour. :slight_smile:
That makes me wonder if that could also be related to dry level of filament. In my AMS, it s indicates 3/5 .

from 11 copies, the one that stands out is:

#9

  • Layer height 0.2mm
  • Wall loops: 3
  • Wall generator: Classic
  • Ironing: Top surfaces - Concentric
  • Sparse filling: grid
  • Sparse infill density : 15
  • Top surface pattern: monotonic line
    I take that the biggest effect comes from the ironing and the concentric setting although I wonder if the concentric setting is not void when ironing is set to true

however, I have 2 settings I will now try out:

  • ā€œonly one wall on top surfacesā€. It looks like the wall numbers did actually play no role on the flat layers.
  • Infill/Wall overlap" : is set to 15%. Maybe bumping it up helps out.

This looks suspiciously like a problem I was running around trying to help someone with in another thread about a landscape topping problem :astonished: :thinking:

Why…hmm i’m still testing in that other thread…

Did the studio/slicer update and do something? is this #2 ???

Odd… but keep at it I will on my side for the other as well i’ll try to find and link the other thread.

EDIT: look at that. while I was sleeping some results.

Where does this model come from? can you attach it if you are allowed? maybe we just need to make it ā€œsolidā€ so the slicer can ā€œseeā€ the edge properly?

Yeah I was watching that thread as well. This model I created myself from a DTM and converted to STL in QGIS.

What s weird is that I used that file on an ender3v1pro and it worked with no issues. It was just taking 5 times for time.

Looks like I cannot share stl files. I’ll sent a 3mf in a moment.

i could not upload the 20MB file. It says it s over 500MB :grimacing:

@Unique_Letterhead , trying with an icloud link: iCloud Drive - Apple iCloud . Let me know if you can access it.
I am actually thinking it might have to do with the STL to 3mf conversion happening at some point or the slicer not able to properly convert the file.

ouch that’s huge most should be under 65mb if even that. so yes very possible that the conversion - like the other model - had something OR is vastly too detailed possibly for the slicer to even get it to 008 you know?

I wonder if you take a resin printer slicer would it look clean?

By accident you might be making too high quality models :laughing:

I’m tempted to try with CURA instead.

But the file is just 20MB big. It s just when uploading it here it says it’s over 500MB. :weary:

You happen to be in luck. my repair FINALLY finished omg… took all damn day on a powerful server as well bah. So now I can start working on these other models to see.

With any luck this will save properly and upload without crashing makerworld <_< this design for whatever reason gave me nightmares oh well. I’ll finish things up tomorrow and see about these repairs.

sneak peek haha

Edit whoops:

sigh im tired eh… haha i got the file i’ll see

Looks good here? So good in fact I think I’ll print it in the matte clay color I am printing with right now (10h sandcastle print going overnight)

I uploaded the file so you can just printer swap and see, but looks great! the topcoat is applying properly on the infill with no holes, and this is without ironing as well so nice!

BUT this also means…there is or might be some problem with you slicing it… I hope this was a fixed file maybe? not the broken one that somehow works on my end?

print Moucherolle150x150x 3h 008LHEF MATTE.gcode.3mf (6.0 MB)

hmmm in your presets, you seelected 0.08mm extra fine. I used 0.20 . Can it be what makes the difference (and the printing time)?
