I am new to pritinting and still run my first roll of PLA - printing bigger and more time consuming things as I go along.
The question I'd like to see answered by the software is "Is there enough filament left on the roll for the print at hand ?"
My expectation would not be on the milimeter, but a fair warning that I might not have enough filament would be awesome. Of course the user would have to enter the size of the currently used roll, but that would only happen upon roll switch and could be an optional feature anyways.
I do not see this on the top of your priority list (not even close) but I though it would come in handy.
For the time being: How do you solve this ? (I mean is there an alternative to guessing from what you see or just hope there is enogh)
