Setting in Cura is grayed out and not changeable

[wuk986 0]

Hi!

 

I am new to the community and 3D printing and I am using the Elegoo Neputne 3 pro with the Cura 5.3

Unfortunately I am struggling with TPU and the retraction speed setting. I did a lot of reseach and watching YouTube videos to get a feeling what could cause the problem and have no idea.

In my other profiles e.g. PLA it is also grayed out.

 

The thing is, when I create a custom profile, do some changes, especially the retraction speed and safe the profile. After safing this setting is not change able any more.

In the description is mentioned this setting is not used because it is overridden. See the screenshot.

 

 

I tried to set the retraction speed in the material without success.

The calculated print time after slicing was the same as before and the print result too.

 

Therefore I have no idea what setting I have to made to make this setting active again or where to change the retraction speed if it is grayed out in the profile.

 

Thanks and kind regards

You may notice that in Cura, some settings are indented. The indented settings are "more specific" versions of their parents. The slicer actually only looks at the more specific version, and the less specific version is only there as a convenience for the user.

 

In the case of "Retraction speed", there are more specific speeds for the actual retraction and for the priming ("unretracting"). If you set the "Retraction speed" setting, then that normally sets both the "Retraction Retract Speed" and the "Retraction Prime Speed". If you, or the profile, put a specific value in either one of those settings, than the "Retraction Speed" setting is no longer used for that particular setting. If you, or the profile, put a specific setting in both the "Retraction Retract Speed" and the "Retraction Prime Speed", then the value of "Retraction Speed" would no longer be used at all (because both settings that use its value are getting overridden). To visually show that the value is not used, Cura disables the setting. Once the more specific versions both have their own values, the more generic setting is simply irrelevant.
