No.  Sorry.  But it's easy to characterize a filament.  Print a cube with NO SHELL and 100% diagonal infill.  Slice it at 100mm/sec so that 100%=100mm/sec and 300%=300mm/sec.

Slice it at your most common layer height e.g. .1mm.

Start printing.  Adjust temp and speed and look carefully at gaps between each line - if there's a gap you are printing too fast (minor underextrusion).  Keep notes.  Within an hour you have a nice table of temperature versus speed.  Print at half the max speeds.  or at least significantly slower.

Kind of like this:

Sorry for bumping an old thread, but I was just curious how you calculated flow (mm^3/s)? I'm assuming area in the volumetric flow equation was calculated using line width and layer height. 

 

Where flow is q=V*A, V=velocity (mm/s) and A=area (mm^2).

    The formulas have been explained somewhere on this forum, but I don't know which keywords to search for (I don't remember in which context or topic it was). Maybe you can find it back? At the nozzle-end it started with line-width x line-height x speed, if I remember well, but the rest for the feeder etc., I forgot.
