Flow rate compensation factor. What is it?

Recommended Posts

There is a couple of settings in the Experimental section in Cura 3.6.0. "Flow rate compensation factor" & "Flow rate compensation max extrusion offset". What do these two things affect? 


I couldn't find any documentation or explanation for these two settings. The tooltips in Cura for these two are a bit cryptic.

Some materials are a bit strange when you extrude them. If you ask for 100 (whatever the unit is, doesn't matter), some materials only extrude 96 (or something like that).

This is mostly an issue for machines that have flow measurement (Such as the S5). There are basicly 2 things that you can do to fix this. If you don't have a flow sensor, you "simply" pre compensate for this factor. So instead of asking for a 100 if you want 100, you ask for 105 in order to get a 100. The problem with that is that if you have a flow sensor, it will give a warning (Because you asked for 105 and got 100, which should be seen as underextrusion).

Those two settings are meant to be used to solve this problem.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
