What's your real max print speed?

Pick your filament and hotend, enter your layer height and line width, and get the max print speed its flow rate allows.

Filament × hotend flow

Max flow is the limit your hotend can melt; print speed above it under-extrudes. Values are starting points — run a flow/pressure-advance test to dial in your machine.
