I am modifying some Slic3r config parameters and comparing the results. How can I have two instances (or equivalent: I would like to see two model windows with their associated configuration screens) of Slic3r at the same time? I'm on OS X, but if there is a generic (e.g. within Slic3r) solution that will be preferrable.
You could duplicate the application by clicking on the application and pressing Command (⌘) + D, and then run both - although I'm not sure if that would mess with the preferences. I haven't fully tested it, but both instances opened up and worked, seemingly ok.
You could even rename them to something other than "Slic3r" and "Slic3r copy" to remind you which application is slicing which model, for example:
- "TestCube" and "Benchy", or;
- "Slic3r-TestCube" and "Slic3r-Benchy", or whatever.
However, Mark's answer seems much more elegant.
From a terminal window, run the command
open -n -a slic3r
Each time the command is executed, a new instance of Slic3r is created.
As per Carl's note, keep in mind that both instances of Slic3r will be sharing the same configuration files, so it will be safest not to save configuration changes while both are open.
