I can't give you a specific number, you have to find the correct value for your specific case. Sometimes, even with different 3D models and different brands of filament, you have to make changes to the settings for each specific case. You have to find the correct value by doing experiments. I guess the correct number is somewhere between the two numbers you mentioned.

There is an ironing option, maybe this will help you to erase the traces of lines on the upper part of the model

@@Edward_Black_Rose i will try and tell you later, thanks

It is necessary to do tests with small models to find the exact settings for your printer and the bottles you use. I constantly change the settings, because each model, each situation requires different settings. I'll give you some examples that I'm currently using, and then you should change them depending on the results. I use a temperature of 245 degrees The bed heating is off but I use paper glue Flow 164 build plate adhesion type - brim brim line count 2 (if your model is tall and comes off, make more 6 and more) I turn off the retraction option and turn on combing mode. 3D printing is constant thinking and learning. It is not to set some settings and stop thinking about the settings. Before each print, some change is required, and a lot of experimentation. I have seen what precise things you are doing, well done I am impressed!

@@Edward_Black_Rose Thank you so much my friend thank you for your kind words I will definitely keep your teachings in mind You are a very good person thank you again and wish you all the best
