I found this previous question about sharing settings and, while I agree that there are no 'best settings' because it depends on your printer, and sometimes the model being printed, I think we can still help people by posting some generic advice and indications for settings.
I mean that if, in order to print Material X on my printer, I need to print at 30mm/s with a temperature of 220°C and an enclosure, it is highly unlikely than another printer can do it without the enclosure, at 80mm/s with a temperature of 190°C. (Those are completely random numbers.)
Materials behave similarly no matter the printer, thus such advice might help people and draw some more people in as those Q&A would appear on Google searches.
I think what would also bring people would be to do this for non-standard materials, ie not PLA or ABS, but stuff like wood and glow and carbon-fibers and so on.
What do you think?
