 When you get a new filament spool, unwrap it, and weigh it.  Mark the empty spool weight on the spool (if you bought a 1 kg spool, and the whole thing weighs 1340 g, it's a safe bet that the empty spool weighs 340 g).   When you get a new filament spool, unwrap it, and weigh it.  Mark the empty spool weight on the spool (if you bought a 1 kg spool, and the whole thing weighs 1340 g, it's a safe bet that the empty spool weighs 340 g).  
  
-When you're going to run a multihour print and not absolutely certain that there's enough filament on the spool, weigh it and subtract the empty spool weight. That tells you how much filament is on the spool.  Then you can compare the weight of the filament on the spool to the slicer's estimate of filament required.  Cura, Simplify3D, and maybe others, provide estimates of required filament.+When you're going to run a multihour print and not absolutely certain that there's enough filament on the spool, weigh it and subtract the empty spool weight. That tells you how much filament is on the spool.  Then you can compare the weight of the filament on the spool to the slicer's estimate of filament required.  Cura, Simplify3D, and maybe others, provide estimates of required filament.  Slic3r estimates volume of filament used and puts it in the gcode file, near the end. Multiply that number by the density (1.25 g/cm^3 for PLA and 1.05 g/cm^3 for ABS) of the filament to calculate the mass of filament required for the print. 
  
 Measure and calculate average filament diameter.  Filament rarely averages out to the nominal 1.75 mm diameter.  0.03 mm diameter error makes a visible difference in print surface quality.  I typically measure in 20-30 places and calculate the average from the measurements.  Mark the diameter on the spool for future reference.  Use that filament diameter when you slice. Measure and calculate average filament diameter.  Filament rarely averages out to the nominal 1.75 mm diameter.  0.03 mm diameter error makes a visible difference in print surface quality.  I typically measure in 20-30 places and calculate the average from the measurements.  Mark the diameter on the spool for future reference.  Use that filament diameter when you slice.

 For maximum print quality, print slowly.  In spite of posts you may see on the internet, there's absolutely no shame in printing at 30 or 40 mm/sec. For maximum print quality, print slowly.  In spite of posts you may see on the internet, there's absolutely no shame in printing at 30 or 40 mm/sec.
