Prusaslicer on linux on a chromebook ...issues  

RE: Prusaslicer on linux on a chromebook ...issues

chmod a+x filename (or just chmod +x filename) is generally the correct way to make a filename executable.  You can see the current permissions by running 'ls -l filename'.  The first bit of the output will be something like "-rwxrwxr-x".   If you see something like "-rw-rw-r--" instead, it is not executable.  The 'x' stands for eXecutable (the others are Read and Write, and three sets for the file's owner, group, and everyone else).

If you run ./Prusaslicer.AppImage I would expect some output or a window to appear.  Do you get your prompt back?  If so, it exited without printing anything which would be a bit unusual.  Which appimage did you download?  Also, what do you get when you run "uname -m"

RE: Prusaslicer on linux on a chromebook ...issues

Also, what do you get when you run "uname -m"... x86_64

All varieties of Is-I xxx  (I tried various spaces and the printout wasn't totally clear to me...all returned...    Is :command not found

run ./Prusa.AppImage  also returned Is :command not found

My original message said I changed the name to Prusaslicer.AppImage.    That was incorrect.  I changed it to simply Prusa.AppImage

You asked what file I downloaded.   That name will be in the following message.

RE: Prusaslicer on linux on a chromebook ...issues

Since I changed the name on the original file, I can't easily tell you which one I downloaded.

It is still here on my file manager, but I can't get copy and paste to work for some reason???  It is the top one of the three that Prusa downloaded to me, I believe Itis pretty long, and I doubt that I could type it out correctly without Copy and Paste.  I will now read the article that you referenced.  Thanks for your help.

RE: Prusaslicer on linux on a chromebook ...issues

I just read the article. It sounds like Prusa has the same issues that Cura did when they updated their versions. 

IF...one finally gets the slicer installed (current version)... one can't load or save any files.  Cura has, supposedly, been working on the issue but hadn't solved it recently.

If that is the case (no SAVE or LOAD) then loading Prusa won't help me now. My workaround for Cura was to load an earlier version that didn't have any issues with LOAD or SAVE.  

For the last 5 or more years, I've only used Chromebooks. Simple, cheap, fast, and powerful enough for my limited needs.  Then, I decided that I needed a Windows machine due to the Cura problems.    It is looking like I might have to buy another !#!$#$ Windows machine.  I simply wanted two fully operating Prusa machines, but...at what cost?  Yikes... no wonder my hair is all turning gray!  Ha ha     thanks..R

p.s. another option, I guess, is to use Octoprint or something similar.  I truly want to stay away from that mess, as wifi service in my long, skinny house can be problematic, even with a booster down the hall.   Dont spend anymore time on my issue.  Thanks, anyway.

I found an old Windows notebook; loaded Prusaslicer and GoogleDrive onto it. It is SLOW,  but should solve my issues.

RE: Prusaslicer on linux on a chromebook ...issues

I did get PrusaSlicer-2.5.0+linux-aarch64-GTK3-202209071828.AppImage  to run (the GTK2 one did not work).  But the file selection dialog really didn't work well at all (didn't respond to mouse clicks or touch screen input except on the (open, save, cancel buttons)).  So I tried the PrusaSlicer-2.5.0+linux-aarch64-GTK3-202209071828.tar.bz2 version and had the same result.  Then I noticed that I could use the tab and arrow keys to navigate around the file selection dialog and was able to load a stl file.  I was also able to slice and save the gcode.

That "ls -l" command is: ell ess space dash ell (all lowercase).  To run that appimage, just type

./Prusa.AppImage

RE: Prusaslicer on linux on a chromebook ...issues

Wow..thanks for all of the effort. I may give it another try, though the lack of a Standard way to Load and Save still gives me pause. Obviously, you are smarter than the guys at both Prusa and Cura who can't seem to solve the problem.  If they would publish your workaround, a lot more people would use the program(s).  Chromebooks are something like 50% of all purchases by schools.  regards, R

RE: Prusaslicer on linux on a chromebook ...issues

I got this to work by using the GTK2 version of PrusaSlicer.  I tried it in the past, but got an error about a missing library, and so just went to the GTK3 version which didn't complain about the library.  But the GTK3 version has the screwy fileselection dialog that doesn't work well.  So I decided to go back to the GTK2 version to see if I could get it to work.  One additional package was all that was needed.

Download PrusaSlicer-2.5.0+linux-aarch64-GTK2-202209071659.AppImage and move it into the Linux file area.  Then in linux terminal,

chmod +x PrusaSlicer-2.5.0+linux-aarch64-GTK2-202209071659.AppImage
sudo apt install libpangoxft-1.0-0
./PrusaSlicer-2.5.0+linux-aarch64-GTK2-202209071659.AppImage

Loading an stl and saving the gcode and 3mf all worked as one would expect.  I should have tried that sooner.

RE: Prusaslicer on linux on a chromebook ...issues

Jim B.  thanks again. I haven't had time to try even your first installation advice.  We've got the kids here for Christmas, so, after they leave...probably on Monday...I'll give it a try. 

One wonders why Prusa hasn't come up with the same answer. It probably is low on the "need" list, but...there are a ton of Chromebooks out there. 

I did see a reference someplace that said that Prusa 250 works on Windows; Macs; Linux AND Chrome OS.  I didn't see a download for Chrome OS, so, perhaps the writer just wanted to give some encouragement to Chromebook users????  

Again, thank you very much for your efforts.  I hope this post helps some other old fool to load PS on a Chromebook.

RE: Prusaslicer on linux on a chromebook ...issues

I take it you have been through this https://help.prusa3d.com/article/install-prusaslicer_1903   ?  I don't have a chromebook but saw this link from a previously closed issue on the PS github.

RE: Prusaslicer on linux on a chromebook ...issues

Thanks,  I haven't seen that one. I did a SEARCH for Chromebook/Linux/install Prusaslicer and NOTHING came up. I'll read your LINK and see if it helps. 

I think Jim B has already given me the path to load PS onto my CB/Linux.

Thanks, again. R
