+==== Max Volumetric Flow and Ludicrous Mode ====
+TL;DR: Be careful with Ludicrous mode with some filaments. It can cause clogs, air printing, and incosistent extrusion.
+There is a limit to how much filament a printer can heat, melt, and extrude per second. This is called "Max Volumetric Flow" (MVF), and it's measured in mm^3/s. Bambu's PLA Basic profile sets MVF to 21 mm^3/s.
+MVF acts as a speed limit on all toolhead motion. For example, if MVF is 21mm^3/s, the max speed the toolhead can do while extruding is ~280mm/s. When you slice a print with these settings, the slicer will make sure to never move the toolhead faster than 280mm/s.
+Bambu printers have "Sport" and "Ludicrous" modes, that essentially speed up all motion the printer makes during a print. **These modes ignore the MVF speed limit.** Bambu's profiles are pretty conservative, and a lot of the time, your filament's MVF is higher than the profile, so it's fine. Sometimes you can get an off spool, or you're using a different brand or type of filament that can't melt that fast, and it can cause you issues.
+It's safer to do your own [[https://wiki.bambulab.com/en/bambu-studio/Calibration#max-flowrate|MVF calibration]] (enable developer mode in Bambu Studio first!), and up the speeds in the slicer.
