Re: Drivers 1.7.5 RC2 with Slic3r Prusa Edition (Updated 18 Nov)

> I am going 45 minutes slicing on this and I am on a very powerful computer. This is unusable. S3D sliced this in about 2 minutes.

The fractal pyramid is a one of a hell complex object. Indeed, the fractals have an infinite complexity by definition. This model and the various chain fabrics are a benchmark for slicer optimization, but they are not what the most people print. It is true, that Slic3r has not been optimized for such models and it is on my list.

I guess so. After 4 hours the progress bar had not moved from about 1/8 complete. I would hate to see how long it would take on a laptop or more conventional computer!

Not trying to be negative here!! I really appreciate all the hard work.

I am always happy to help test anything if you guys should ever need. Hardware - software, I am always game!!

Thank you PRUSA Team!
Can you help me please - could not find any 0.15 settings 😥

I see you are on a mac? I think I read something about you have to import the settings for the new build. I may have read it on the facebook group for this printer.

Re: Drivers 1.7.5 RC2 with Slic3r Prusa Edition (Updated 18 Nov)

Hi,

I am awiting delivery of my Prusa MK2 and installed the 1.7.5 driver and attempted to run the Prusa3D Slic3r MK2 application but the following message appears:

"LoadLibrary failed with error 11114; A dynamic link library (DLL) initialization routine failed"

Any ideas?

Gareth

I found if you had slicer installed previously, you need to delete the preferences to get a clean install. Otherwise background processing will be turned on by "default". That said, I find slicing times are still beyond useable with supports. S3D slices in minutes, not hours. YMMV.

(I'm on a Mac, so the preferences are in my home directory in a . file)

> But now even the old version of Slic3r is not working any longer in Ubuntu.... 🙁

You somehow got the new Slic3r installed over the old one, but likely only partially. I suppose you did not configure the perlbrew correctly.

The simplest you can do right now is to use our linux binary package. I have verified it runs on Ubuntu 16.04.1
https://github.com/prusa3d/Slic3r/releases/tag/version_1.31.6

Hi Vojtech,

Slic3r has been running well in my Ubuntu system for a few months, but now I have a new laptop and I am running into a problem with the installation again.

I downloaded and extracted the Slic3r-1.31.6-prusa3d-linux64-full-201611202210.tar.bz2 file, then in a terminal changed directory into the extracted folder with the slic3r file, then type ./slicer to run the program.
That used to work on the old laptop, it started Slic3r.

But on the new laptop it does not start the program, it just puts out a very long list of text about the Slic3r program.
p@p-ThinkPad-P50:~/Slic3r-1.31.6-prusa3d-linux64-full-201611202210$ ./slic3rSlic3r 1.31.6-prusa3d-linux64 is a STL-to-GCODE translator for RepRap 3D printers
written by Alessandro Ranellucci <[email protected]> - http://slic3r.org/

--save <file> Save configuration to the specified file
--load <file> Load configuration from the specified file. It can be used
more than once to load options from multiple files.
-o, --output <file> File to output gcode to (by default, the file will be saved
into the same directory as the input file using the
--output-filename-format to generate the filename.) If a
directory is specified for this option, the output will
be saved under that directory, and the filename will be
generated by --output-filename-format.

Non-slicing actions (no G-code will be generated):
--repair Repair given STL files and save them as <name>_fixed.obj
--cut <z> Cut given input files at given Z (relative) and export
them as <name>_upper.stl and <name>_lower.stl

I think it must be due to a simple setting change somewhere, but I cannot find it.
Perl seems to be up to date (5.22.1-9)

Any help would be much appreciated!

Also, have you tried installing from the PPA instead? https://launchpad.net/~santilli-gabriele/+archive/ubuntu/slic3r-prusa

Thank you very much, I was not aware of the PPA option. Did you set that up recently?

This is what I did:

Extract the Slic3r-1.31.6-prusa3d-linux64-full-201611202210.tar.bz2 file.

Open a terminal and
~$ cd /home/p/Slic3r-1.31.6-prusa3d-linux64-full-201611202210
Then
~/Slic3r-1.31.6-prusa3d-linux64-full-201611202210$ ./slic3r

But instead of the Slic3r program starting, as it does on my other computer, the text that I showed in the previous post appears in the terminal, describing the ins and outs of Slic3r instead of running Slicer.

Yes, the PPA is only a few weeks old. It will add a Slic3r icon in your Unity Dash or start menu etc.

Does it start if you type "./slic3r --gui"? If yes then I'm not sure what's forcing it into command line mode. You could try to delete the ~/.Slic3r/ folder.

Missing libraries. 🙂

The easiest solution is to use the PPA as it will install everything for you.

Otherwise follow the instructions to install all dependencies.

Go for the PPA it is the easiest way to install and update in the future. This is what I did and I was up and running with Slc3r within minutes. Just make sure to get the Prusa specific configuration files.

Cheers, but what instructions do you mean I should follow to install the dependencies?

Looks to me (who knows very little of Linux) as if it is looking for bits and bobs inside of the Prusa Slic3r folder, not elsewhere on my Ubuntu system. I may be very wrong about that.

Do I need to install dependencies on the system or in the Slic3r-1.31.6-prusa3d-linux64-full-201611202210 folder?

Thanks for any advice, Mik

No, it is looking for libglut.so.3 which it can't find in your system, either locally or globally.

Do I need to install dependencies on the system or in the Slic3r-1.31.6-prusa3d-linux64-full-201611202210 folder?

On the system is the easiest way. And, again, the PPA will do this for you, and automatically update when the new Slic3r comes out, so it's the best method for less advanced Linux users.

Cheers, but what instructions do you mean I should follow to install the dependencies?

https://github.com/alexrj/Slic3r/wiki/Running-Slic3r-from-git-on-GNU-Linux

See the lines in General Libraries -> Ubuntu 16.04

Looks to me (who knows very little of Linux) as if it is looking for bits and bobs inside of the Prusa Slic3r folder, not elsewhere on my Ubuntu system. I may be very wrong about that.

Thanks, I got it working now. I had to install the General Libraries for Ubuntu 16.04 from the page you linked above.

The command:
sudo apt install build-essential libgtk2.0-dev libwxgtk3.0-dev libwx-perl libmodule-build-perl git cpanminus libextutils-cppguess-perl libboost-all-dev libxmu-dev liblocal-lib-perl wx-common libopengl-perl libwx-glcanvas-perl
did the trick. After it downloaded and installed a lot of stuff, Slic3r now starts with the ./slic3r command in a terminal.

I ran the other two commands as well, just in case they are needed sometime later:
sudo apt-get install -y libxmu-dev freeglut3-dev libwxgtk-media3.0-dev
sudo apt-get install libboost-thread-dev libboost-system-dev libboost-filesystem-dev

I prefer not to use PPA's when I can, because I don't understand how they work and what security vulnerabilities I might introduce by allowing automatic software updates from PPAs.

Security wise there is no difference compared to downloading the binary and running it. By default you are prompted about updates so you can always double check what's going on.

(Actually, it can be argued that the PPA is more secure because it is signed, so as long as you can trust that I will keep my private key safe you are much better off than copy and pasting instructions from a website.)

(I write this mostly for everyone else reading here, not trying to convince you and happy to help with installing from sources when I can.)

So if you did not keep you private key safe, then someone else could change the files and install malware along with (or instead of) the Slic3r software update?

If that is the case, then you yourself should also be able to do this.

Or is there some built-in security mechanism that prevents the person running a PPA from making unauthorized changes?

Not accusing you of anything, sorry it must come across a bit like that, but I just don't understand how these things work. 🙂

Exactly like someone else could put malware instead of the Slic3r binary you are downloading. In fact, a website password can be guessed, a 4096 bit RSA key cannot.

Unless you download the source code, study it to make sure that no malware has been hidden within, you are trusting a bunch of people and companies to have kept their passwords and keys safe.

(I'm a software engineer, among others I work for a financial company. I do know how this stuff works.)
