The Illustrated Guide to Building a High Speed CNC Router

What is "Building the KRMx02 CNC"?

It's a workbook that takes you step-by-step through the process of building your very own high speed, heavy duty CNC. As a bonus by purchasing the workbook edition from this site, you gain access to our private KRMx02 forums.

"No matter what your experience you can build this machine!"

Cutting Aluminum Booms

KRMx02 Making Aluminum Booms

I needed to reduce the weight of three aluminum booms for a Y6 Hex-copter I am working on. The booms are made from 1" square aluminum stock. The plan is to remove some of the material from the boom by cutting slits and holes into the sides and top. This would will reduce the weight while still keeping the structural rigidity of the square tube. . . .

KRMx02 Workflow Example

CNC Part Creation Workflow

New to CNC these examples may help

In this project, I am going to take you step-by-step through the processes I use creating a part on my CNC. I will start with a idea take it from the drawing stage all the way thorough to the completed part. Even if you don't need this part, I recommend you follow along and actually create the part with me as I take you through the process. . . .


Kronos Robotics AirExchanger

I am dust crazy. I go to all lengths to keep dust out of my shop. I have a monster central cyclone system and several high end shop vacuums, many with there own small cyclones as well.

The AirExchanger allows you to push the router cooling exhaust air out the sides without affecting the air inside your dust shoe. This allows for a smaller more efficient shoe.

The AirExchanger It took me almost a year to develop and I hove one installed on all my machines. . . .

KRMx02 SuperPID Upgrade

SuperPID Speed Controller

The Super-PID is a closed loop speed controller that enables Mach 3 to take control of your router. Mach 3 will be able to start and stop your router and control its speed to as low as 5000 RPM. . . .
