I'm running Linux Mint 17.1. I was running RepetierHost 1.0.6 with Slic3r 1.1.7.
I created a fresh install of Repetier Host 1.5.6 and untarred Slic3r 1.2.9 into the RepetierHost directory. When I select Slic3r as the slicer and click on the Configuration button it lists all the Slic3r options in the log window instead of opening the configuration window.
I ran the configureFirst.sh script and all my packages are up to date.
I tried removing my ~/.Slic3r directory will all my settings in it and it made no difference.
I tried removing the ~/.local/share/RepetierHost directory and it made no difference.
Suggestions?
