Can someone tell me witch parameters I need to change so my overhang touch the wall? Slowing the overhang speed seems to help a bit, but it’s not reaching the result I’m looking for.
Your pictures don’t look like overhangs. It looks like the infill is not reaching the outer wall perimeter loops.
What do yo have for Strength > Advanced > Infill/wall overlap ?
Can you screenshot your settings for the “Strength” tab?
It’s at 15%, that’s the default value.
Those look good. Is this PLA?
What about your “Sparse infill” settings?
Yes it’s PLA. And for more precision, cuz I just realise that it was maybe not clear, the pictures above shows the bottom layers of a supported surface. The printer just finished the fist layer above the support I stopped it cuz I saw that. I cleaned the support and took the pics from under the part.
I was not 100% clear so this is the first layer on the support base ?
Can you slice the part and post a photo of the speeds at this layer ?
Oh. I am confused now.
Yes please post some slicer preview pictures, so we can understand what we’re looking at.
I have similar density issues with Text etc face down on plates with gaps.
I am not sure as the lines otherwise look good and tight, its just touching the curvature etc,
Can try forcing a closer density, smaller lines to close the gaps with lowering line widths?
The 2nd photo just looks odd… wierd adhesion\extrusion… here the right angle “wall” part has also lifted or flowed poorly, and then the lines are also further away than lower down - probabily same isssue related.
Hi DruiD,
Sounds like your problem is the first bed layer. The best thing to do is slow it down and see what happens. Each type of filament has its own happy spot.
You might have to change the ( seam gap ) to a lower setting or zero and if using the classic wall generator you can add a mm value setting to ( filter out tiny gaps )
Test this out just to see if you get improvements then you can adjust for your filaments or you might have to adjust the line width or first layer height also.

Keep us updated
This is what the slicer show for the first pic:
And this is the second pic:
Please note that I took the pics from under the part and the screenshot from above.
Here’s the layer in question in is entirety and the layer under that shows the support:
Thx everyone for the help.
I just seen you are using pla.
What is your supported top Z distance
What is your Bridge Speed
What is your bridge flow ratio
Also the Orca slicer has more bridge settings you can change so you know
you can even change the internal bridge speed low for this part.
Keep us updated
Sorry, I didn’t keep you updated. I managed to reduce the gap between my bridge/100% overhang and the wall by reducing the printing speed for bridge. I had to go to 6mm/s in order to get the result on the picture. I still don’t know why the printer don’t reatch the wall when faster, the travel should be the same no matter the speed it’s look like the printer like to take shortcut when ask to go faster.
If I want the bridge to reatch the wall shouldn’t I increase the flow instead of reducing it?
Sorry I had petg on my mind was late at night brain was off lol
PLA Settings:
-
Bridge flow can be 1.0 to 1.4 range you have to test the filament
-
Bridge speed can be 10 to 50 mm/s you have to test the filament
-
Top Z distance 0.17
-
Bottom Z 0.17 or 0.20 if needed
-
Interface spacing 0.2 to 0.33 with .4 nozzle I like this range with my filament
-
Top interface layer 5
-
Bottom interface layer 2
-
Base pattern spacing 2 + or - as needed
-
XY distance 0.50 & range can be 0.2 to 0.8 for most parts
Keep me updated
The slicer have also had some bugs on this
