Selecting the material for your CNC machine

CNC machines can be built out of a variety of materials. If you’re going to build a CNC machine, it’s up to you to choose the best material to do it with. One of the main things that will determine the best type of material to build your CNC machine with is what you’re going […]

Spindle vs. Router

Hobby CNC machines typically use either a spindle or a router. While these two devices appear similar, they each have distinctly different characteristics.

Best hobby CNC control software

You can have a CNC controller be as simple as a parallel port from your computer, or as complicated as a dedicated synchronized multi-axis board. But no matter what you choose, you’ll need some sort of software to control it. This article will show you the more popular options to actually control your CNC machine […]

Cheap CNC Motion Control

After you have your motors and motor drivers ready to go, you’ll need to have a way to actually control the motion of your motors. CNC motion controller may seem like a simple problem, but the fact that your motors will need to run in a highly coordinated fashion along with the fact that that […]

Choosing the Right Stepper Motor Driver

Choosing the right driver for you stepper motor is important because it will allow you to get the maximum amount of performance out of your motor. There a few types of drivers available, each with their own characteristics.

Choosing the Right Stepper Motor

Choosing an appropriate stepper motor for your CNC project is important. If you choose a motor that is too small, you may experience very slow maximum speeds and torques, and even missed pulses. On the other hand, if you choose a motor which is too big, it may require a powerful and expensive power supply […]

Bipolar vs. Unipolar stepper motors

There is a lot of discussion on whether to use bipolar or unipolar stepper motors for your CNC project. Each type of motor has different characteristics, but when all is said and done, the best choice is usually bipolar stepper motors. This article is a short explanation why bipolar stepper motors are usually the better […]

Choosing a Stepper Motor for your CNC Machine

Choosing an appropriate stepper motor can be difficult and time consuming. This webpage is intended to help you easily and quickly select a good stepper motor for your project. There is a lot to cover, so consider this the first part in the series

How to Couple Threaded Rod to Stepper Motor

After selecting the threaded rod or ACME screw you intend to use for linear motion, you need a way to effectively connect this rod to a stepper motor such that there is zero slip when the motor is rotating. I’ve found a number of articles about this subject, but I’ve found many of them give […]

Linear power transmission for CNC machines

Threaded rods vs. ACME rods There are many methods of accomplishing linear power transmission, otherwise known as linear movement. Anything from a simple wheel, to a gear on a rack, to rubber belts will work. However, for hobby CNC machines, the most common method to accomplish movement is using threaded rods, or ACME rods.
