CNC Machine Hardware and Plans
These are my hand picked components and hardware for the perfect leap into this CNC process. You will also get the cut sheets and plans for cutting the necessary MDF pieces for a CNC design that can be made with conventional power and/or hand tools. Includes all of the hardware necessary to build the CNC router: Linear bearing angles (bored and tapped), cross dowels, couplings (1/4" to 1/2" on all three axes), bearings for the linear rails and lead screws (24 - 5/16" and 6 - 1/2") , and the nuts and bolts at various sizes. The lead screws and rails are not included. Now, go out and buy that $9.00 MDF and get started. This package is available now and shipping!
The size of this machine if built according to the measurements in the plans, will travel 40" in the x direction, 20" in the y direction and 5" in the z direction. Other table sizes are possible by altering the measurements in the plans and providing the necessary reinforcements. mechanical components include couplers.
This kit also contains many enhancements from that of the tutorial. The y-axis is appropriately reinforced to minimize any deflection. The x-axis is also well reinforced. Each piece of the kit is precisely cut. The Combo comes with all of the hardware needed for assembly, couplers, bearings and the plans for the MDF pieces. The ready made MDF pieces shown in this image is for illustrations purposes only.
Parts that you will need are the MDF sheets, aluminum or steel angles, lead screws, electronicsfor interfacing to the computer and software which can be gotten for free in many cases.
Parts that are included in the Hardware kit:
These items are offered to minimize the effort to purchase all of the hard to find components and the many types of fasteners.

Jack Rehak's Inspiring Build
Meet Mr. Rehak, an 80 year old (2012) bright CNC Machine enthusiast. Jack built his blackFoot CNC machine in short time considering his available resources. Jack's modifications to his blackFoot are quite inspirational and worth a look. Moreover, Jack has set-up a very inventive workspace and resources to handle the various tasks such as loading sheets, hose/cable management and means of control.
Step 36 - Software Toolchain Part 3 - The toolchain concept
At this point, you should have the control software that is described in Software Part 1
and Software Part 2
. Software part 1 shows the process to install Mach3
and Software Part 2 shows the process to install a Linux control software application called EMC2
. If you're still unsure what I'm talking about, then here is my detailed explanation of the entire workflow. Later posts will go into greater detail and tutorial on each program.
A DIY CNC Machine in Pipe
I have been doing a lot of tinkering lately (yup, that's why!). I cannot get the mechanical aspect of CNCs out of my system, so until then, enjoy the crazy concoctions.
New Vertical Oriented CNC Machine
Coming soon!! This is a first look at the new vertical CNC machine that we will soon offer. This is a result of customers looking for a smaller footprint, but still wanting the full 4 feet by 8 feet cutting area. The machine will be called the greenLean.
To Start: Basics and What You Should Know
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
A CNC machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend. Each day I will add video tutorial steps to get you through the build with very basic tools, little knowledge of machinery, mechanics, or electronics; but I must warn you, these machines are inherently dangerous, so wear the proper protection and use common sense. At the very least, read the instruction and precautions on every tool you use. I am especially not responsible for relationships gone bad as a result of the obsession you are about to embark.
From Sketchup to CNC Fabrication and Built Assembly
In this tutorial, I show you how to draw a complex assembly in SketchUp, take that drawing and build upon it with machining operations (tool paths) in CAM, cut out the parts on the greenBull CNC Machine, and build the assembly completely.
The CNC Process: From CAD to Product
I have put together a video tutorial of the entire process from drawing a part in CAD (Computer Assisted/Aided Design) to the final product that is cut out from the CNC machine. This three part series will step you through the design of a very simple object that uses drills and profiles. Drills are simply holes created from the end mill (router bit) into the material and profiles are horizontal cuts, usually in geometric form, that create various shapes.
New York World Maker Faire 2013
We will be participating in the New York World Maker Faire
2013, September 21st and 22nd. This is a Maker Faire that I have always wanted to attend, and we want to bring a 3D Printer. But, not the same type of printer that you always see at the Maker Faire. Typically, you would see the 3D Printer that is based on the FDM technology (Fused Deposistion Modeling), like the whiteAnt
. As always we want to bring something unique. A 3D DLP Printer that uses photopolymer that hardens when a specific wavelength range of light hits it.
Step 35: Software Toolchain: EMC2 Under Linux
Before I get farther in the software toolchain for the Windows operating system, I will cover the primary software for Linux. If you are partial to Linux, or you think Linux is some kind of animal and don't know what the heck I'm talking about, this alternative software toolchain may interest you. This tutorial would not be complete without covering the open source side of CNC computer controls. You may find that using EMC2
(the CNC control that runs under Linux) may be a bit more problematic than Mach3 since there is limited CAD (design software) out there for the Linux operating system. Yes... I said, operating system. I you don't know already, Linux is an operating system about as old as the Windows operating system.
Step 34 - Software Toolchain Part 1 - Mach 3 Installation
Now we come to the software section of this tutorial series. What's a software toolchain anyhow? Well, my fine feathered machinist... A software toolchain is a "chain" of software that enables the completion of an entire process from design to implementation. When I say chain, I mean a few programs.
William L's Scratch Built CNC Machine
Here is a scratch built
machine (from the plans or book
) that exhibits great workmanship, but more importantly, how some of the construction of the CNC machine was done. William L. used sound techniques to make sure the machine would be constructed as intended, knowing that some of the machine would have various size differences within the sub assemblies that would make some of the measurements within the plans not work.
Octavio's Metal CNC Machine
Octavio went out on a limb and created a metal machine with some very inventive components. Inspired by this website, he was able to get this design and construction going. The machine is truly an example of using components in the machine for efficiency and simplicity. The overall structure appears to be steel. He uses bearings with channels to serve as linear guides. The z-axis mechanism is reversed to enable longer travel. All of this is not the most interesting part. Octavio is a medical doctor. This goes to show that individuals of all backgrounds dabble with this technology. Take a close look at the bearings used to guide along the rail (U groove and V groove bearings work well for this type of linear rail mechanism). I know, you're saying that this method is used on other CNC machines. Sure, but he is positioning the bearings and using minimum hardware to serve multiple purposes. You can see that he is using the same shaft for each pair of bearings. The back bearings (the bearings to the right) glide horizontally along the y-axis and the front bearings serve the z-axis up and down movement. This linear motion mechanics for the y and z axes is very clever. Octavio is currently trying to reduce the gantry weight. He says that the z-axis alone is 50 pounds. He has a goal of 20 pounds by changing the metal to aluminum using stamped parts.
