" I want to ask how to determine the speed of the desktop filament extruder machine? Is there have any scale at the button?, If have may i know."

For most Makerbots the speed which is typically set using the slicer software, is approximately 80mm per second. Thats without the acceleration per the FW as well as other settings such as jerk or coast or without speeds set as a % of the 80mm/s for a part of the object such as a feature or a wall.

Most Mendels such as the Prusa i3 or the Ender 3 have settings that are usually slower; 40-60mm/s due to the momentum of the Y axis which includes the mass of the moving bed.
