I have made a temperature ⨉ fan speed tower which needed 3x9-1 ChangeAtZ post processing scripts and it took me quite much time to configure them all (and check it twice). Is there a way to save this, so that I wouldn't need to make them all again if something went wrong and I needed to start over or if I wanted to do something similar again ?
I'm a Simplify3D user which allows one to save "factory" files. It appears that Cura supports printer profile configuration and saving.
From the above link, one is directed to enter the profile manager. You can duplicate an existing profile and rename it to separate it from the protected (standard/stock?) profiles.
Without using Cura to confirm this, I suspect that you'll discover this may be the solution you seek.
Thanks to fred_dot_u, I found the solution : the post processing scripts configuration is saved... in the printer profile. So, you cannot directly duplicate it, but re-installing a second occurrence of the same printer will clear the post processing scripts list, you can get them back by selecting the modified one...
