Sam S. and His Hacked redFrog

Torque and Linear Motion Formula
Periodically, I get questions from users of the site regarding torque and how much is required to move certain masses and a recent user emailed me specifically and it gave me the happy motivation to add this page. :) These masses are things like the gantry, or the z-axis assembly with the router mounted moving on the y-axis, or the just the router mount and router within the z-axis assembly.
