# Extrusion Parameters These helps in control over the Flow rate and enabling custom line width. Adjusting the flow multiplier directly adjusts how much material is placed down. The main use case for flow multiplier is to compensate for some fault in the extrusion. For instance, if the nozzle is slightly clogged, this can cause underextrusion. Increasing the flow could then push more material through the clogged nozzle, hopefully causing it to end at the right amount of material. This can also compensate for slip or variance in filament diameter. {% hint style="info" %} It is almost always better to fix the actual problem causing the overextrusion or underextrusion, but adjusting the flow can be an easy temporary fix. {% endhint %} If you want the lines to be wider, it is better to enable the Custom line width setting. The line width doesn't necessarily need to be the same as the nozzle size. Adjusting the line width will also adjust the spacing between the lines which prevents overextrusion and underextrusion. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.c6.fabheads.com/modules/print-settings/advanced-settings/extrusion/extrusion-parameters.md?ask= ``` The question should be specific, self-contained, and written in natural language.
