Slic3r 0.9.8 Is Out! Looks Good Too! smileys with beer
January 19, 2013 02:31PM


Exciting news in the DIY 3D printing world: Slic3r Beta 0.9.8 has been released... and it doesn't suck! winking smiley

Slic3r is an open source slicing program (duh... winking smiley ) that takes a 3D model (an STL) and converts it into a tool path for your 3D printer.

Slic3r is much more user friendly than some of the other slicing programs on the block. Slic3r is also very quick to generate G-Code. Slic3r can generate g-code in seconds, unlike other slicing programs which can take minutes (or hours).

So far after testing v0.9.8 on a few prints, I am VERY VERY pleased with the results. The last 7+ releases of Slic3r were burdened by fatal flaws: program crashes, not lifting the z-axis to the correct heights, pimples and rashes on your prints (the Slic3r STD). I actually have not adopted a new Slic3r version since 0.9.1 because of these problems.

This Slic3r release appears to be, fast, stable and intelligent. In my book, all of Slic3r's dirty sins are forgiven winking smiley I am adopting version 0.9.8 as my new primary slicing program smiling smiley

Slic3r GodFather, Alexrj (aka Sound), recomends you upgrade to version 0.9.8 too:

"This juicy new release contains many bugfixes and improvements. Work focused on stability and print surface smoothness, removing gaps, spikes etc. You're advised to upgrade to this version... or provide a good reason for not doing that. ;-)"

In truth, a lot of the "new" features I am gushing over (intelligent narrow path infill etc.) were added in versions 0.9.7 or earlier... the trick is that the nasty flaws in those versions stopped me from using them.

I can't recommend enough that you run over to www.slic3r.org and add Slic3r 0.9.8 to your 3D Printing arsenal.

Also Be Sure To use this calibration guide (a nice hidden gem) to get the best prints from Slic3r: [github.com]

So is that a testiment to "Sound" preferring Repetier host to Pronterface?

I'm still new here and haven't tried anything besides pronterface/slic3r/Marlin as those were what I decided on before I even got my build together.

I have just tried 098 and it looks promising. I think I can say that this is the first release I have been able to make anything good out of (without tweeking my head off) after 072b, still only tried it but it does look promising indeed.
Good on you Sound!

I agree Iceman. While I was a version 0.9.1 user, I had a whole bag of tricks to make that possible winking smiley

0.9.8 is is working "out of the box." The parts are coming out nice and solid (when they should be winking smiley ) . It is refreshing.

Hey Guys,
I just loaded 0.9.8 and starting to play with it. I was using alexrj's extruder calibration page and I got stuck on:

- Open the Gcode file and look for the value for single wall width

Is this somewhere in the opening lines? Do I need to do some math?

These three lines:

; perimeters extrusion width = 0.80mm
; infill extrusion width = 0.80mm
; first layer extrusion width = 0.26mm

Not sure why Slic3r is giving such wide extrusions for a 0.5 mm nozzle, or such a narrow extrusion width for the first layer.

Thanks Cameron for the quick reply.

I was looking back through all my settings and for some reason I had "First layer extrusion" at 130% instead of default 0.

After changing it and redoing the extrusion test, I am spot on. I can't believe I was getting good looking prints with being off so much. I was making 1.2 mm walls when it was calling for 0.8.

Set your own width. Try a 2.2 "width over thickness"

Example:
0.2mm layer height
0.44mm width


For your first layer, consider trying something thicker and wider (but still a 2.2ish ratio) for better adhesion.

Example:
0.3mm layer height
0.66mm width

You can shoot for thinner heights and thicknesses; there comes a point where you will not be adding quality and only adding time to your prints. Find your sweet spots and adjust based on the job at hand.

I've never seen a slic3r setting "width over thickness". This confuses me as I've seen several people refer to it...
Is this the same thing as "default extrusion width"? Sounds like it's not.

Do you mean that it's best to manually set "default extrusion width" based on your selected layer height?
Re: Slic3r 0.9.8 Is Out! Looks Good Too! smileys with beer
January 24, 2013 11:03AM
You got the idea. It is not a single setting. "Width over thickness" is your extrusion width divided by layer height.

Usually a width over thickness ratio lower than 1.8ish can be troublesome.

I have played with super high and low ratios though. You will be surprised what is possible when you tinker with your printer and its settings smiling smiley

Sounds like it should be a tick-box option next to "default extrusion width"---- "Use ratio xxx instead" ;-)

Thanks for the clarification Idol

Take that up with Sound lol. I proposed something similar on the Slic3r github and did not get any traction...

Honestly so far I've been doing fine leaving "default extrusion width" at "0", which must be using a similar ratio. But definitely should have an option to change the ratio itself, rather than either-or.

I'll throw it in the suggestions on github when I have some time. I know he's busy with more important things typically. Maybe if I catch him on IRC again.

In the meantime it's pretty easy to do the math myself. I think. (where's my calculator?) ;-)

2 things I'd love for Slic3r is:

1 to be able to export ALL setting in a single bound (I can use 2 different computers) I know you can do the active ones at once. (I ddn't see any files in any folder that seemed to be the paramaters. unless I'm missing something )

2 have it default to a different output folder. I like to have the STLs in one and a second folder for whats queued up to print.
Re: Slic3r 0.9.8 Is Out! Looks Good Too! smileys with beer

On Linux i believe that folder is .slic3r (hidden folder)
Re: Slic3r 0.9.8 Is Out! Looks Good Too! smileys with beer
January 28, 2013 08:11PM
Bingo! Thanks
(~/library/Application support/Slic3r on the mac.)
Nw to find it in Windows (though, the windows machine is a distant secondary)

Just pulled and built slic3r v0.9.9dev from github. Used an unaltered old config from v0.9.3 and it produced some really beautiful prints. (A prusa y-motor-mount and a set of extruder herringbone gears).

First layer now has the correct height, and there are zero bumps on the outside of the print.

I would also recommend to upgrade.

I'm getting this error on a few STLs

Can't call method "retract_length" on undefined value at /slic3r.app/Contents/Resources/lib/std/Slic3r/GCode.pm line 258

@anode, start with a fresh config for the new version and manually enter your settings.
Re: Slic3r 0.9.8 Is Out! Looks Good Too! smileys with beer
January 31, 2013 04:33PM
I get the "retract_length" error on everything I have tried. This is my first time using slicer, so maybe I am missing something. But it just doesn't work for me. I have tried different values for the retraction, but it doesn't seem to have an effect.

Anyone have and then solve this issue?

So happy to read all this good feedback! \o/

Slic3r has been under active development for one year, and you know, development snapshots are unstable by definition. 1.0 is the goal for stability, and we're going there thanks to the community supporting with feedback.

@anode505, @pfinucan, can you export your config (File menu -> Export) and attach it here? I'd be glad to give it a look.

Oh crud! I found my retract error prob, but forgot what it was. But I think it was something about too small a hole/layer or the like. (or it *might* have been a SAE drawing in a mm system)
Re: Slic3r 0.9.8 Is Out! Looks Good Too! smileys with beer
February 01, 2013 11:05PM
can you upload an stl and give other people a try. i have both slic3r 0.72b and 09.8 installed. can try them both. currrently set for 3mm retract.
@anode I have the exact same problem. It's accompanied by this error

No layers were detected. You might want to repair your STL file and retry.
@Sound Do you want to see my config.ini or do you think the retract error is secondary to the "No layers detected" error?

@jamesdanielv I'd be glad to upload the stl in question. How would I do that exactly? I'm new here.
