yinyarr started following Feature request - Extrusion multiplier - where is it?
Cura 3.2.1. The extrusion factor can be entered in the MATERIAL section under FLOW. There is also an extrusion factor adjustment for the initial layer (Initial Layer Flow). Those working with 3D printing for some time usually look for the "extrusion factor" terminology. However, the popup description is clear on using FLOW for this function. I find the pop-up's really helpful.
