"Empty Space"
November 18, 2013 08:47AM
Hi guys,

Sorry, I do not know what the actual name, The Empty Space, I use pronterface, with profile selection: Huxley-PLA-03-02 on both objects in the photo I attached is indicated by the red arrows.

And, several times like these, also in: Huxley-PLA-05-03, the holes there, I had to patch it using putty.

Is there a way in which the application pronterface can resolve this? Thank you.

Regards,
Heri

Those gaps occur when your slicer (eg. Skeinforge, Slic3r, etc) determine that there isn't enough space to extrude a line of filament. For example if that's a 0.4mm gap then you can't fit 0.5mm of filament into it. You could try scaling the models up by a little bit before printing, or switching to a narrower nozzle. You could also try setting a lower value for the extrusion width in your slicer, which is a little bit like faking a smaller nozzle in software.

Slic3r has a "gap fill" function which can often take care of small gaps like that, but it can be a bit messy sometimes.

Thanks 4MULE8, maybe I should change the overall design with a new one, and this is the first time I used Slic3r to change the settings that I attach, also with prints.

Yes, it is messy, probably because I do not know the settings to use Slic3r, can you help?

Those screenshots show that you do have gap fill enabled.

What do you have for the extrusion width (found in "Print Settings" > "Advanced")? If you're using the standard 0.5mm nozzle you could try setting the default extrusion width to 0.4mm with the rest left on 0. That should generate tighter paths in the g-code and might be enough to fit another another line of filament in the gap.

Sorry, I do not understand this: ... with the rest left on 0. I will give you the attachment again. Is it like that?

Sorry, those tabs have confusing titles don't they! winking smiley The extrusion width settings that I was talking about are in "Print Settings" (the second tab) not "Printer Settings" (the fourth tab).

If you made any changes to Extruder 1 in "Printer Settings" (the screenshot you sent) then you should undo them. Setting some of those to 0 is a bad idea on a Huxley! Retraction length should be about 3mm, retraction speed should be about 45mm/s and minimum travel after retraction should be about 2mm.

Oh yes, sorry, you're right grinning smiley, I was wrong to see it, thank you for reminding me, and a new profile attachments. Maybe they replaced it with: Device Settings.

And the attachment of, Print Settings - Advanced, I just change it at the Threads (2 to 10), I think it could fix it but instead, it was made ​​a long time in doing the slicing process.

Try to increase number of perimeters
Re: "Empty Space"

The attached image using a value of 2 on the perimeter of the previous 4.

From the picture, number 1: there are holes, but number 2: the hole in the Skeinforge can be handled by Slic3r. if slic3r and skeinforge could be combined grinning smiley.

Also try to setup under Print Settings tab - Infill tab -- Solid infill threshold area value of 0.1 mm2
Re: "Empty Space"
November 26, 2013 02:27AM
Thank you, I've just tried with solid infill threshold area: 0.1mm2 (infill 0.1mm2.png), and the result is in the attachment photo (dt 0.1 mm2.jpg), there is still no significant change.

And I give you the model to try (dt_lubang2 3.STL), you may want to try to print it out and give me input.

Try to setup Infill - Fill density: 1
and if it not infill all try to increase no of perimeters by one
Re: "Empty Space"
November 26, 2013 10:43AM
Sorry, I do not understand the sentence on the second line. What do you mean like this: if the use of infill can not be done, then adjust as perimeter with 1.

While waiting for an answer from you, I'm trying to do what I do understand.

Sorry my mistake English is not my native language I mean BY 1 or to increase you value of perimeters by 1
I want to say: acording to you last attachment named: infill 0.1mm2.png (29.8 Kcool smiley
To setup Infill > Fill density 1.0

if it doesnt help go to Layers and perimeters and increase number of perimeters by one. eg if you now have 2 perimeters increase it to 3 perimeters with option Generate extra perimeters when needed. Or if you have 3 perimeters increase it to 4 etc...

Hope this helps

Well, thanks for the explanation from you, and I will give it a try. By the way, I'm from Indonesia and also always use Google Translate to write this grinning smiley.

Hi guys,

The empty space that was to be filled by using Slic3r, with the change in the Advanced> Extrusion width with: 100%. Except for the First Layer: 200%, which from the beginning had been like that.

And it all became filled with PLA, very solid.
