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. The question is usually in the form of, can my ??? oz-in motors be used on your CNC machine.

Step 30: Router Mount Part 1
This tutorial is dated, if you are considering a CNC for your personal use, we would highly recommend purchasing a kit that is very stable from our wide range of machines available. The first of the videos for the router mount is finally edited and ready to post. The z-axis bearing supports were made in the current shape to be able to hold the router with a piece of stock in-between containing a hole for the router. This hole will need the ability to tighten against the router for stability and leveling. For my machine, I'm making one mount. This router mount will be positioned around the upper part of the router housing. Later, I will be installing a vacuum connection which will also serve as increased support for the router.

How To Have Two Motors on a Single Axis Spinning in Opposite Directions on a CNC Machine
In this tutorial we will demonstrate how to have two motors on a single axis spinning in opposite directions with the use of a hex inverter.
