The extruder motor (E values in G-code) only determines the speed component of that equation (again, this is the one with the physical delays caused by the distance between extruder motor and hot-end). 

 

I'm sorry to say that I can't agree with you. I'm afraid that you have some misunderstanding about the extruder and the flow rate. If this is offending, I feel deeply sorry. Thank you!

    Np, it's fine to disagree on something, as long as it's civil 🙂

     

    Anyways, Cura is open source, so if you have ideas and/or abilities to write something that could solve this (for either modifier meshes or adaptive layers), feel free to do so!

    I believe that Adaptive Layers is a great idea. It automates and perfects the manual approach based on modifier meshes. It's absolutely a great idea. Thank you!

    @curasurf - you are totally correct.  Multiply those 3 numbers to get the volumetric flow.  If the volumetric flow is constant then the speed of the extruder is constant and the flow is constant.

     

    However of course you slow down on corners.  the printer doesn't actually go at the full speed requested.  It slows down on every corner based on the individual printers setting for "jerk" and acceleration.  Also when there is a travel move, flow goes to zero briefly.

    Ah, I think we were confusing print speed (movement in xy direction) with extrusion speed (how fast the extruder motor pushes out the filament). In my posts I meant the latter.
