Variable extrusion width
Hello
I would like to know if there is an option for a variable extrusion width based on layer height.
I try to print this in vase mode and the lines on the bottom part are much closer to the ones on the upper part.
I want to print the upper lines in 0.8mm extrusion width and the bottom ones in 0.5mm as it seems in prusaslicer that that number will be ok.
When I print it all in 0.8mm extrusion width I get some fuzziness on the perimeters. You can see it on the attached image.
So the solution would be to have a variable extrusion width but I can't really find it in prusaslicer.
RE: Variable extrusion width
Right click on the object, select height range modifier. Set the range to whatever makes sense for your model. Right click on the range, select Add Settings→Extrusion width. You can have multiple height range modifiers per model.

Thank you very much.
I feel very dumb. You see, as extrusion width was under advanced, I pressed that and didn't saw it so I thought there wasn't such an option but it is separate from it.
I'm just blind🤦.

Happens to the best of us 🙂

Ok I did that but now I have another problem.
I get the error shown in the photo which doesn't make any sense.
RE: Variable extrusion width
Oh yes, I forgot you mentioned vase mode… ☹️
Not possible with vase mode — to my knowledge. See https://github.com/prusa3d/PrusaSlicer/issues/4230

RE: Variable extrusion width
Yes thank you.
I searched about it and found the issue.
As I see it I could edit the gcode adding the height range modifier myself but I can't seem to find the command for that.
Do you know about it?
RE: Variable extrusion width
So it seems I have to do something like this but it doesn't seem to work. I don't know the syntax of gcode so there should be a mistake in there. Can somebody help me?
RE: Variable extrusion width
That's not going to work because by definition in vase mode there are no layers, everything is printed contiguously

RE: Variable extrusion width
Ok then, the z position.
How do I write that and where?
The start gcode?
RE: Variable extrusion width
I could do another thing.
If there is a command for setting the extrusion width for a specific kind of line then I could add it at the layer height bar at the preview screen as a custom gcode.

Can anybody help me with this?
RE: Variable extrusion width
I don't think what you're trying to do is possible --if you want to print in vase mode. Sure, in normal mode you can use modifiers or add custom code at a layer height. But in vase mode, no, at least to my knowledge. There may be some serious gcode editing that makes it possible but that's beyond what I can offer.

RE: Variable extrusion width
Well if there is no command for setting extrusion width then there is a third option.
Height range modifier creates a gcode.
If I take that gcode and copy it to the vase mode one then that could possibly work.
So I want to know what does height range modifier creates exactly and where to put it in the gcode.
RE: Variable extrusion width
Maybe some other good soul can help you here but I've had nothing but dismal experiences editing gcode directly.

Thank you very much fuchsr.
You were very helpful😊.
If anybody else can help me with this, please do it.
I would be very welcome.
