Introduction:

Generally, the motor shaft with a 1/2" diameter will be inserted in one end, and a shaft, or lead screw measuring 3/4" in diameter will be inserted into the other end or vice versa.

Description:

The screws that clamp the shafts will be tightened. These steel clamping coupling are for use with high torque motors and high inertia when the motor is changing directions.

Step 21: Driver Caps, Resistor Networks and Mosfets
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 resistors are in, right? Ah, I know, you want to see the complete assembly before you dig in. Ok, on to this part of the assembly. Please don't ask me what Mosfets are, but the word sound cool! I can tell you that they stand for Metal Oxide Semiconductor Field Effect Transistor. I have personally read about fifty descriptions of this electronic animal and I still can't figure it out. It doesn't say much for a Berkeley grad! Well, I'm open to some plain English interpretations without the word "drain" in them. Are you still with me?

This creative coupling solution comes from another generous user of the site. He has devised a way to couple the motor to the leadscrew with standard aluminum tubing. Marc has graciously allowed me to show you this creative idea.

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. Well... here we are, finally getting started with the electronics portion of the video series. The entire structure of the CNC machine is complete with the exception of the router mount. We will get to that a little later. For now, we will start on the assembly of the HobbyCNC 3 axis chopper unipolar stepper driver.
