Selecting the right stepper motor - Torque test of Nema17 and geared Nema17

In this episode we talk about how to convert the torque specifications in Newtonmeter to something more graspable, like kg/m, or lb/inch. We look at the datasheet of a Nema17, and field-test our conversion with different weights. A 27:1 metal-geared Nema17 will also be put to the test, lifting 2.5kg.

I am quite new to producing videos, so I am super thankful for tips, comments and suggestions on how to improve!

(P.S.: I noticed the irritating focus-behavior too late, next time I will set it to manual focus)
