Slic3r - cannot overwrite a system profile error

Dec 11, 2018 3:57 pm

Hi,
I have been trying to modify the printing temperature settings in Slic3r. Under Linux and Windows I keep getting the same error, even if I open Slicer as root.

What am I doing wrong? Why are the default printing temperatures so high? 215 for PLA, 255 for ABS?

It's a good idea to have the baseline profiles to go back to if you screw things up, so the system profiles are read-only. Just save it with a new name. If nothing else, put the date on it.

So next stupid question. I can't seem to find the + sign or whatever it is, whit which you add new profiles. Where is it?

Just load a good base profile, modify any settings you like and save. Give it a new name. It's essentially a "save as".

I had a related question, but figured it all out while I was recording the video.



Switching tabs should refresh that dropdown. I had some issues when I thought I was using a user profile when actually it was using a default profile. It was just the UI hadn't updated.

You can fix this in the GUI. Just change that "==" in the default profile dependency to ">=" to use a profile with multiple nozzle sizes:

The other trick to using a single print setting profile with multiple nozzle sizes is to use "0" as your extrusion width. That will calculate a suitable setting at slice time based on your current nozzle size:

The dependencies you were looking at are in the printer profile notes field:

The dependencies are good when you have a lot of nozzle and other hardware combinations and want to only show the valid selections that will work with each combination.

I've added some notes on this topic to my project notebook.
