Need education on how Cura saves (or doesn't) the print profiles

[ljbeng 0]

Here is a scenario that happens all the time.  Cura 5.4.0

Open a known good profile.

Edit retraction from 4 to 6 for a test. 

Do Not save that profile.

Open another existing profile (that had retraction set to 2.0)

Guess what?  The retraction is still set to 6... ???  Why?

 

Thanks.

Because 2.0 is the default value and there is no definition of the retraction in the second profile. So open it doesn't change the value ?

Let me know if I am wrong...

 

I start with the standard profile and change parameters A,B,C and D.  I save this as Custom1.

I start with the standard profile and change 4 different parameters, E, F, G and H.  I save this as Custom2.

 

I now start with Custom2, slice, print then select Custom1.  I now have a profile loaded with ALL 8 changes, A,B,C,D,E,F,G and H???  This seems to be what is happening and ruining prints and hours of time.

As long as you made sure to base Custom2 on the standard profile, then that sounds like it's not behaving as intended (because Custom2 should inherit all the settings from Standard, which is all of them). Try it in the latest version to see if it's still a problem (delete and recreate the profiles because they'll automatically be carried over just to make sure). If it still doesn't work then submit a bug report about it (make sure to include a zipped copy of your Cura configuration folder so they can check your profiles). Unfortunately I can't replicate your problem myself.
