A bit later, but I ran across this question because my printer (which is has a direct extruder, not a boden) has a 0.6 retraction distance, and the default Cura retraction is 6.5mm. Every time I would switch to one of the default profiles and reset my settings, if I forgot to change the retraction, it would freeze up my extruder by pulling filament too far back into the cold-side of the extruder. There is not a way to set this inside the Cura UI on a global, printer, or extruder specific way. Its actually very annoying. This should be one of the settings in the Extruder settings in the printer configuration. @GregValiant's response was very helpful, as a starting point, but ultimately led me to the following, which actually provides the "Printer Specific" setting that the OP had requested (and which I am after). Also, his directions were using Windows Paths, and I run Linux. I had to do a little bit of web-searching to find the Linux places "config" in ~/.config/cura/{version}, but printer, extruder, and quality profiles are all located in ~/.local/share/cura/{version} In any case, for a printer-specific configuration, under the "definition_changes" folder, find the definition file for your Printer. In my case, my printer is named "RatRig V-Core 3.1", and the filename is "RatRig+V-Core+3.1_settings.inst.cfg". As @GregValiant instructs, open this file and under the [Values] section, add the necessary retraction sessions as outlined above (with your correct values). Save the file, and restart Cura. Note that "Current Settings" may not change, but if you reset back to the Profile's "default" settings, those settings should reflect the new values, assuming that they are not overridden in your custom profiles. Personally, I open the entire "~/.local/share/cura/{version}" directory into VS-Code, and search the entire directory structure for the settings of interest, to ensure that I don't have other profiles or configurations which override them.
