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
