[img]http://airwolf3d.com/wp-content/uploads/2012/06/slic3r.jpg[/img] Exciting news in the DIY 3D printing world: Slic3r Beta 0.9.8 has been released... and it doesn't suck! ;) Slic3r is an open source slicing program (duh... ;) ) 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, [url=https://github.com/alexrj/Slic3r/issues/851]pimples and rashes on your prints (the Slic3r STD)[/url]. 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 ;) I am adopting version 0.9.8 as my new primary slicing program :) Slic3r GodFather, Alexrj (aka Sound), recomends you upgrade to version 0.9.8 too: [i]"This juicy new release contains many bugfixes and improvements. Work focused on stability and print surface smoothness, removing gaps, spikes etc. [b]You're advised to upgrade to this version... or provide a good reason for not doing that. ;-)[/b]"[/i] 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 [url=http://slic3r.org/]www.slic3r.org[/url] and add Slic3r 0.9.8 to your 3D Printing arsenal.

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.

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.

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

Thanks for the clarification Idol]]> xclusive585 General Thu, 24 Jan 2013 11:10:19 -0500 https://reprap.org/forum/read.php?1,177808,178948#msg-178948 https://reprap.org/forum/read.php?1,177808,178948#msg-178948
Usually a width over thickness ratio lower than 1.8ish can be troublesome.

I have played with super high and low ratios though.

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?]]> xclusive585 General Thu, 24 Jan 2013 10:51:26 -0500 https://reprap.org/forum/read.php?1,177808,178840#msg-178840 https://reprap.org/forum/read.php?1,177808,178840#msg-178840
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.

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.]]> Purple Kerbie General Wed, 23 Jan 2013 18:16:12 -0500 https://reprap.org/forum/read.php?1,177808,178777#msg-178777 https://reprap.org/forum/read.php?1,177808,178777#msg-178777

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.]]> NewPerfection General Wed, 23 Jan 2013 16:17:25 -0500 https://reprap.org/forum/read.php?1,177808,178774#msg-178774 https://reprap.org/forum/read.php?1,177808,178774#msg-178774 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?
