How do I make a new default material?

[AliRassi 7]

my initial guess was that you define your default material somewhere in the machine configuration files (Cura profiles!)

so I looked and found :

        "preferred_material": "generic_pla",

I changed its value to "generic_abs" hoping it would change my default material but nothings happens!

the new material name also matches the name of its file in "materials" folder in "resources"! 

and I also checked and it's not in the excluded materials in the definition file!

any thoughts?

I couldn't reproduce this. I did the following:
1. Change "preferred_material"  to "generic_abs"
2. Start up cura

3. Add the machine that i just changed the prefered material of.

 

It showed generic abs as expected.

Oh yeah!

it only works when you add your printer once you have changed the definition file!

I was hoping to see the changes being applied after having a printer set up (for example how it updates the variants_name or has_materials)

thanks for clarifying!
