Volumetric speed
-
Hi,
I have see that Slicer 2 include volumetric speed...
Exists some system for search volumetric speed of my printer

The maximum volumetric speed depends on your hotend and the material used. With PLA on a standard e3d v6 heatblock and 1.75mm filament on a .4 nozzle the maximum volumetric speed is 15mm^3/sec. A volcano hotend goes up to 25mm^3/sec.
The prusa profiles for different materials have material specific volumetric maximums set, but they assume a standard setup such as above. So if you use the PLA profile you may need to tweak it for volcano hotends.
When I looked into this I found http://projects.ttlexceeded.com/3dprinting_calibrating_volumetric_rate.html which may help you find out specific maxima for specific setups.
You will reach maximum flow by setting really fast speeds for the different print speeds. Autospeed is quite buggy (doesn't work well with gap fill speed !=0 and gapfill speed 0 disables gap fill; depending on geometry features will print at weird slow speeds).

This step of the ender 3 guide goes into finding the volumetric extrusion limit: https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40#s177

Thanks, very interesting
