How to upgrade Repetier-Host installation

I have Repetier-Host v1.0.6 running on my Ubuntu box, and I want to upgrade to the latest version.

How do I do this without losing my settings? I assume that I don't have to do the same thing as an initial installation.


  • Well, you do the same as first install. Data is under linux in $HOME/.mono/.... and is not affected by an upgrade.
    Make sure you have a current mono if you update. 3.6 at least I think is required.
  • Great-the new install of repetier-host works. But, it did not install the latest Slic3r. I tried coping the bin, lib, res and dll folders from the new Slic3r over my existing, and now when I slice, I get:

    23:49:44.057 : Slic3r command:/home/awander/Desktop/Printer/RepetierHost/plugins/Slic3r/bin/slic3r --load "slic3r_settings.ini" --print-center 0.00,0.00 -o "composition.gcode" "composition.amf"

  • That is right, we do not bundle slic3r for linux any more. You have to install that independently and in slicer manager set the path to your slic3r.
  • I understand that. What I don't get is how to install the new Slic3r. I copied all the directories over the ones I had already, so the path should be the same.

    But I get those errors, which I can't make heads or tails of. 

    Do I need to chage somethinng in Slic3r files themselves, in order to work with Repetier?
  • You should read on the linux installation guide or download linux binaries in case they work on your distribution. It has many dependencies that make installation difficult especially with all the different distros, which is why we do not include it any more in first place.
