Mach3 CNC Controller software will convert your PC into a fully functional 6 axis CNC Controller. Mach3 is one of the most popular CNC Controllers for both DIY and Industrial machines. Mach3 works on most Windows PC’s to control the motion of motors (stepper & servo) by processing G-Code.

Mach3 is a feature rich program which is also easy to use. It works with other programs and will import DXF files, generate G-Code, fully customizable. Works with CNC Routers, Milling Machines, Lathes, Plasma Cutters and Lasers.

If you are here on this page now it is because you want to make your CNC machine work faster and more reliably.

Mach3 CNC Controller SoftwareYou want a solution that is proven and you don’t want to waste your time searching the web to find out how to use it.

I KNOW how to make a CNC machine work faster and more reliably, because I have spent years learning how. When I built my first CNC Router it was finicky and unreliable and the software was a pain to work with. It was frustrating back then, because I couldn’t find a PRACTICAL and FEASIBLE way to control my CNC machines on a hobby budget.

I searched everywhere on the web and I got really discouraged. The information I needed was scattered all over the place and I couldn’t find one solution that solved my problem. Until I found Mach3.

I want to save you the pain of learning CNC the hard way like I did. I want you to succeed fast. So I decided to piece together the methods that WORK into one single location so that folks like you and me  can get their CNC machine working without having to sift through all the garbage (thousands of blogs and forums) to find out what works. Mach3 CNC Control software will get you going.


Benefits of Mach3:

  • Transform your PC into a fully functional, 6axis CNC controller. No need to pay for a high priced controller panel.
  • Mach3 makes it easier to work with the files you know and love. You can directly import DXF, BMP, JPG, and HPGL files through the free LazyCam addon.
  • You can see what your G-code is doing with the Visual Gcode display.
  • Can’t afford stand alone CAM software? Well Mach3 can generates Gcode via LazyCam or Wizards.
  • If you don’t like the way the screen looks you can change it. Mach3 has a fully customizable user interface with lots of free and paid, ready made screen sets.
  • If you don’t see a function you need, you can write your own with Customizable M-Codes and Macros using VBscript.

  • Different materials require different speed and feeds. Cut better more accurate parst by controlling the spindle speed with Mach3.
  • Remotely turn equipement on or off with Multiple relay control. No more ruing parts because you forgot to turn on the coolant.
  • Manual pulse generation
  • Video display of machine
  • Touch screen ability
  • Full screen eligibility

Mach3 has successfully been used to control the following types of equipment:

  • Lathes
  • Mills
  • Routers
  • Lasers
  • Plasma Cutter
  • Engravers
  • Gear cutting

“Mach3 is a CNC Game Changer.”

Morrisville Router  When I got started in CNC 15 years ago, the only CNC software available was DOS based, or too expensive for a hobbyist to afford. Then Mach3 came along and changed everything. Mach3 turns my PC into a very powerful, easy to use CNC Controller. I no longer had to memorize long strings of arcane commands just to make the machine move. With Mach3 I could see what the machine would do before it did it and make corrections right there at the machine.

For me, Mach3 is a CNC Game changer. It allows me to be productive and get work done without worrying about the software. I can see what my machine is doing and make changes while it is cutting. I spend less time programming and more time cutting.

Your Purchase Is 100% Protected

Try Mach3 before you buy it and see if it is right for you. Download the free Demo version of the software and try it on your machine. You have nothing to lose and everything to gain. Use my free video tutorials to show you how to set up Mach3 for your CNC Router table and cut an actual project*

All I ask is you try out Mach3 on your machine. Use the demo version of the software to ensure the program is applicable to your needs before you buy it. Take as long as you need.

When you KNOW that Mach3 is the software for you, come back and get a License from me.

It is the nature of internet licensing that refunds are impossible – Once a license is generated it is not possible to be “returned”. Therefore, please utilize the Demo versions of the software to ensure the program you purchase is applicable to your needs beforehand as ALL SALES ARE FINAL.

(*some limitations apply).

Wait. There’s More…


Wizards are “mini-programs” that extend the capabilities of Mach3.  Wizards can be written by anybody and are designed to allow users to quickly perform routine or convenient operations without the need to have a  pre-written GCode file.  Included with Mach3 are free Wizards for such things as:

  • Gear cutting
  • Digitizing
  • Holes
  • Slots and keyways
  • Text engraving
  • Many standard shapes
  • Surfacing
Also available, for a fee, are the Mach3 Add-ons for Mill – a handy collection of wizards designed to minimize the time it takes to go from “start to part”.

Without a license, Mach3 will operate in Demo mode. While in Demo mode, the software has the following limitations:

  • Mill & Plasma: 500 line gcode limit (10,000,000 limit after licensing)
  • Turn: 50 line gcode limit (10,000,000 limit after licensing)
  • Kernel Frequency locked at 25kHz (only applicable if using the parallel port driver)
  • Set Next Line function disabled
  • Run From Here function disabled
  • Turn: Threading disabled
  • Plasma: THC functions disabled

Non-commercial users (aka hobbyists) are permitted to use one Mach license for as many machines as they require. For commercial users (anybody who uses the software to generate profit), we require a separate license purchase for each machine. Mach1, Mach2, and Mach3 may all be used on one computer, but only one version of each will co-exist on a single computer.

A license is only required on the computer actually running a machine. If a computer not connected to a machine is used to test code, please use Mach3 in Simulation mode – it will remove the 500 line limit. Simulation mode can be accessed by uninstalling (or not installing) the Parallel Port Driver. The Add-ons for Mill will only work with a licensed copy of Mach3 as this software is an Add-on, and not a stand-alone product.

Hard Copies (a disk) of the downloadable content are available directly from a 3rd party.
