[Cerrado] Stable Slic3r builds  

Re: Stable Slic3r builds

Ok, finally I manage to fully compile it (I feel ashamed, I just forgot to run the "perl Build.PL" before "perl Build.PL --gui" 😳 RTFM !!!)

However when I try to run it with "perl slic3r.pl --gui", "wperl slic3r.pl --gui" or "perl5.22.1.exe slic3r.pl %* --gui" I can see the Windows created, but immediatly after perl crashes ... Arg, so close !

I suspect another issue between the chair and the keyboard ...

Re: Stable Slic3r builds

For the impatient, we made a rease of the Slic3r Prusa Edition 1.31.2 on github.

https://github.com/prusa3d/Slic3r/releases/tag/version_1.31.2

This Slic3r shall be used with the updated profiles:

https://github.com/prusa3d/Slic3r-settings

There will be a "drivers" package relased in the following days containing both the new Slic3r and the updated profiles.

Re: Stable Slic3r builds

So whats the trick to importing the various configuration ini files posted. Which ones go where? I see bundles can be imported but not sure which file is for which.

Re: Stable Slic3r builds

Thanks a lot, I'm one one these impatient 🙂

I'm gonna play with it !

I have a question regarding the print setting: Now, every profiles have a 0.2 first layer height. Shouldn't this value be aligned with the first layer height of the firmware, which is 0.15 since several firmware version ? (3.0.6 if I'm not mistaken)

Re: Stable Slic3r builds

You can create a Windows shortcut with the path of wperl and slicer.pl, and using --DataDir to provide the settings dir.

I use this one:

D:\dev\Slic3r-1.31.2-prusa3d-win64-full-201611011502\wperl.exe "D:\dev\Slic3r-1.31.2-prusa3d-win64-full-201611011502\slic3r.pl" --DataDir "D:\dev\Slic3r-settings\Slic3r settings MK2"

Re: Stable Slic3r builds

Thank you sir.

Re: Stable Slic3r builds

Anyone know the solution to this error -

Sorry, but you gave us too little information. I suppose you built Slic3r on Linux from the sources?

The minimum Z value 0.15mm in firmware tells the firmware to not go below this height, which also means you will not be able to print thinner 1st layer. It is perfectly all right, that our default Slic3r profiles set the 1st layer height above the firmware minimum height. It would be a problem, if it was vice versa.

Re: Stable Slic3r builds

You guys said that you're performing some beta tests of the next release already, so we can expect an official build soon, I guess. The waiting is a pain nevertheless. Any chance that you might install a build-server that provides nightly builds for us all? As I cannot convince Wx to install on my machine (I don't like Perl and Perl does not like me), it is not possible for me to join the "open source"-team. 😉

Just as a side note that I wanted to say from the first time I printed with the MK2: The printing settings of Slic3r shouldn't have the first layer height set to a different value than the remaining layers. This has no practical use on a printer with live Z-adjustment capabilities and results only in an odd current layer information on the LCD of the printer. If I want to print at 0.2 mm, I want to do it for every layer. Enhancing the bed adhesion with the live z adjustment option squashes the first layer already, so there is no need to distort the layer height even more. Just my two cents.

Thanks for the clarification, it's not that obvious for me.

I like this version, the top of rounded models are really efficient , my Rocktopus are perfect now 🙂
I like the "Slice now" button as well, very handy to test some adjustment in the settings.
I like the cube infill, seems a good ratio rigidity / infill percentage to me.

I do not what to think about the support improvement, do you have some example of how to get gain from it ?

Still things to do (to layer aligned to underlying infill, manual edition of support features ...), but a nice step forward !

Re: Stable Slic3r builds

They appear very close to release. There are now pre-built binaries/install images for Macintosh, Windows, and Linux off of this GitHub page:
https://github.com/prusa3d/Slic3r/releases

1.31.2 appears to be the new release. Read the release notes, and see the links following that section.

Re: Stable Slic3r builds

Just read the changelog and I am blown away by all the improvements. Great work, guys. Will try the new build later today.

Re: Stable Slic3r builds

> I do not what to think about the support improvement, do you have some example of how to get gain from it ?

Just use the profiles from
https://github.com/prusa3d/Slic3r-settings

and enable supports. If you ever tried the supports before, you will recognize the difference.

Without the sheath and with the improved zig-zag recti-linear algorithm, the supports are much easier to remove. They are very close to Kisslicer or Simplify3D in many regards now. Jindrich, our guys who fine tunes the Slic3r profiles and prints around the clock, finds the new Slic3r supports usable for the first time. Now if you print a complex model requiring supports, chances are, the print will come out better from Slic3r than from Simplify3D due to better seam hiding of Slic3r.

Re: Stable Slic3r builds

Ok I played a bit to compare with previous version and it seems to improve as you told (I need to experiment more).

But on the other hand there is still a major flaw in the way the support need is detected. I used my favorite support torture test, the chopper model. With default setting the back of the hat have a support in place (and it tend to be too small, but that's not the point here, the size of the support could be proportionnal of the mass printed on it until support is not needed anymore):

But if I reduce the angle threshold to 30 °, there is no more support below the back of the hat, meaning this part will be printed on air:

I tried a lot of support setting on KISSlicer to check if I could get the same and I had to put up to 87 ° from vertical to get the same issue (which I think is equivalent to 3 ° the way it's measured on slic3r)
Note that I concentrate on the hat, but the right hand loose his support at 84° on KISSlicer.

I think that KISSlicer have a kind of up to bottom path detection mecanism that prevent hanging part being sliced without support, and that Slic3r does not have (yet ?) the same kind of double check to prevent hanging parts in the air.

Please to not take that as a rant, I really like Slic3r and think it's going to be one of the best, but for me that's the number 2 issue.

Number one is the lack of manual addition or deletion of supported zone. That would workaround the issue detailed here 🙂

Re: Stable Slic3r builds

Actually we provide a Slic3r build for 64bit linux, built on some Ubuntu linux I think.
Please let me know whether this binary distribution of Slic3r works and / or which library needs to be fixed.
Thanks, Vojtech

on Ubuntu 16.04 LTS:

It would be great to offer working Slic3r binaries for latest LTS of Ubuntu 64bit, currently one of the most used linux distros.

Got your .deb installed on Ubuntu 16.04 LTS without issues. Then tried running it:

$ slic3r --gui
Undefined subroutine &Slic3r::FORK_NAME called at /usr/share/perl5/Slic3r.pm line 14.

Any idea what's wrong, please?

I guess I need to make a "proper" launchpad.net recipe...
