One of the features I really like in Astroprint is the reporting. Cancelling prints can be for many reasons and this data might be good for both individuals and a combined trend for the whole community.
I.e.
Cancel Reason dropdown in Print History.
- Cancelled prior to print to change setting (This one could almost be auto detected because no filament is used)
- First layer fail (Again astroprint knows the layer when it is cancelled)
- Spaghetti
- Broken filament (User entered)
- etc etc
Richer reporting data will distinguish you from others and make this both good individual and give great trending data.
