FIRMWARE FEED RATE Vs. PRINTING FEED RATE

Firmware allows you to set a Max Feed Rate for each axis. When Printing there is typically a user change-able feed rate setting.Typically allowing the user to go +/- 100%. If a Print feed rate setting of 150% is selected and you have already config your slicer software to print at the max feed rate you set in FW- How does Marlin interpolate this?

The obvious answer (I Think) is you cannot print faster than you set in FW. But what happens when 1 axis is maxed out but the others still have headroom? What is the ultimate speed limitation?

Thanks for any replies!

You can't print faster than the max feed rate without stepper motor stalls and/or missed steps, so I guess you need to ensure you don't over step the max feed rate whilst extruding.

It doesn't matter if you're just moving the extruder nozzle from point to point without extruding.
