It would be awesome if we could share the benefits of our knowledge and experimentation with everyone. If we could instantly access and download or upload profiles to a shared online library directly into the FFF Process dialogs .
The search parameters would be based on machine, various options (like extruder head types), dual extruders, filament material and manufacturer, and desired printing quality.
For example, on my TAZ 5 printer, with the stock toolhead it took me some experimentation to determine the optimal print settings for Brand X ABS. However, when I purchased "Brand Z" ABS I had to go through the whole process again to find the optimal printing temp (25 degrees different!), bed temp, speed, layer heights. Once I have found that it would be great if I could submit that to 'the cloud' with some notes that could be used/improved/shared by the Simplify3d user community.
A vote up / down and comment feature would be nice to help separate the better profiles from the weaker profiles.
An even better feature would to automagically prompt people at the completion of a print about the quality of the final job (1-5 stars) and submit that along with their profile settings and printer info to a database that could be data-mined and shared.
Sometimes I just want to print something quickly and don't have the time to experiment - this would help give me a baseline to work from.
