Slic3r Prusa Edition 1.41.0 (final release)  

Re: Slic3r Prusa Edition 1.41.0-alpha3

in this and other releases, i noticed when i send the gcode to my printer through octoprint, the rename panel never shows the full file name in the window without clicking anything. in the screenshot, the full file name is 3dbenchy, but only shows benchy. is this easy to fix?

Re: Slic3r Prusa Edition 1.41.0-alpha3

I have the same issue. The text field is always scrolled to the right. The content is okay though.

It would vastly improve efficiency of multi-color printing if the slicer didn't slice each object as if it were stand-alone and then merge them, which is what it looks like it's doing now, because there's wasted "exterior walls" between the objects where they meet in the interior of the object. For example, everywhere that there are walls with two colors touching, like the black, orange and yellow parts of the example in the photo above, the walls are all wasted plastic - they could just be infill, which uses perhaps 10% as much plastic to fill the volume. And by treating the interior as a single object, printing would not only use much less plastic, it would speed the print - both by wasting less time printing unneeded plastic, but also because the interior fill would be a simple grid instead of a very complex set of shapes.

Yes, I know it's a complicated problem to solve. But if the slicer knew that it was slicing a single object, and that the color only mattered in the shell, it could dramatically improve speed and efficiency of multi-color printing.

An approach that I could imagine is that you union the objects and generate volumes for the outer shell and the interior, then slice each object's intersection with the outer shell separately, and slice the intersection of the interior with the union of the objects.

For example, this OpenSCAD does this:

module shape1() {
color("yellow") cube(10);
}

module shape2() {
color("red") translate([10,0,0]) cube(10);
}

module shape3() {
color("blue") translate([10,10,0]) cube(10);
}

module shape4() {
color("green") translate([0,10,0]) cube(10);
}

module onePiece() {
union() {
shape1();
shape2();
shape3();
shape4();
}
}

// Universe cube must be bigger than part being loaded
universe_x = 1000;
universe_y = 1000;
universe_z = 1000;

// t is thickness of shell
t = 2;

// Name of part to convert to shell (must be in same directory)
part_to_shell = onePiece;

module shell() {
intersection() {
onePiece();
minkowski() {
difference () {
// Universe cube
translate([-universe_x/2, -universe_y/2, -universe_z/2 ])
cube([universe_x, universe_y, universe_z]);
// Original part
onePiece();
}
// Tool for the minkowski shell
sphere(r=t, center=true);
}
}
}

// put the color shells and then the interior shapes:

intersection() { shell(); shape1();}
translate([25,0,0]) intersection() { shell(); shape2();}
translate([50,0,0]) intersection() { shell(); shape3();}
translate([75,0,0]) intersection() { shell(); shape4();}

translate([100,0,0]) difference() { onePiece(); shell(); }

when i rotate a 3d file to get a better orientation on the build plate, it wont sit flat on the build plate, but if i slice it and go to preview tab, it displays the layers properly. if i go back to 3d tab, its still below the build plate.

Ummm. That's a jigsaw puzzle. Those walls are supposed to be there.

Same here...

Re: Slic3r Prusa Edition 1.41.0-alpha3

Thank you for all the hard work on this but why is the 2D tab being removed? Am I the only one using it to precisely position objects on the build plate?

I too use it from time to time and will miss the 2D view...

Re: Slic3r Prusa Edition 1.41.0-alpha3

Are there plans to be able to have a UI to rotate items around the y axis? I feel like I do this more often then rotate around the x axis.

Re: Slic3r Prusa Edition 1.41.0-alpha3

I'm hoping the new Slic3r retains the ability to type in rotation angles. It looks like it's heading toward the Cura gui-based method which I find rather clunky to use.

I don't even think there is a slight chance of that going away.

Prusa knows there are times where you want precise rotations like that.

Plus even Prusa Control still has the ability to type in rotation values.

Re: Slic3r Prusa Edition 1.41.0-alpha3

I would like to have a quick and simple cut and alignment pin option for objects. I know meshmixer dose it but i would prefer not to have to keep swaping programs and saving files all the time.

A GUI rotation with configurable snap points would be awesome. I really dislike Cura's rotation feature. For all its quirks, KISS' "make axis up" selection is grand.

I'm pretty sure PrusaControl only has gui x-rotation currently as well, actually. Unless I am overlooking something.

Re: Slic3r Prusa Edition 1.41.0-alpha3

I have a question on the Slic3r program.

First off Slic3r is GREAT and using with Octoprint.

Question is: The bridging on the print has spacing I wish to get closer on and get more of solid surface from it instead of strings.

How to adjust this.
It is only happening bottom side of my print and the first layer after the supports.

Bridging has been one of my big disappointments with 3D printing. I'm no expert, but I've played around with Simplify 3D, Slic3r, Cura and KISS. In my experience, you can mitigate bridging somewhat, but you are not going to get smooth results with the current generation of software or FDM products unless you go with something like dissolvable supports. If you configure no space between the supports and model, you've created a permanent stand. If you add some sort of gap, the 1st layer above it will be stingy. It's printing "on air" essentially, so extrusions will be round.

You can adjust the Z distance between support and part under Print Settings->Support material->Options for support material and raft->Contact Z distance in Slic3rPE 1.40.1+. I've not tried the alpha yet, so I'm not sure it hasn't moved. Again, a 0 will give a fixed interface between layers, so is only useful for dissolvable materials on the i3. I've had good luck with 0.25mm, though others say 0.15mm works. You can experiment with the other settings for the support itself, but don't expect "smooth" undersides.

You might be better off rotating the part, hiding the side with supports, or slicing the model and gluing it for good surfaces. YMMV, of course, so do try experimenting.

I hope they add a feature like the "Align to print surface" in Simplify3D, where you select a triangle on the bottom of your model and it rotates it to be flat with the print surface.
According to the GitHub, they are planning on adding that feature, or it has been requested a few times. Either way, that was one of my favorite features of Simplify3D, and since using Slic3r PE, I've missed using the feature.

I've found at least one feature that I really like in each slicer that's missing from the others. For me, the killer features that keep me hopping between slicers are:

Unfortunately, each one seems to have one or more limitations that are deal killers for some situations or everyday usage. Hopefully, somebody will compile a list of "best of" features for incorporation into "The One" slicer to rule them all. If Slic3r could add custom support placement, it would cover 95% of my needs.
