Mach3 CNC controller software

Mach3 Overview

Mach3 is a powerful and practical CNC controller software designed to control CNC router, CNC mills, CNC plasma, CNC lathe, and other CNC machine tools. The software interface is simple and intuitive, and users can adjust the corresponding parameters according to their needs. And it has many functions such as numerical control testing, high precision machining of complex parts and clearing of corresponding data.

Mach3 CNC controller software is an open CNC system, simple operation, convenient maintenance, open, stable performance, and low-cost new CNC system. The standard PC computer is completely converted into a full-function CNC controller, and the highest 6-axis CNC control, Directly support a variety of DXF, BMP, JPG, HPGL file format input, visual G code display, direct G code generation, spindle speed control, multiple relay control, manual pulse generation, including a large number of processing strategies, video display, and touch screen , Full screen display, digitization. Three-dimensional dynamic display tracking, automatic tool setting, program jump execution (breakpoint memory).

4. CNC Laser Machine.

5. CNC Plasma Cutter.

How Does Mach3 Work?

Mach3 is a type of CNC software that runs on a PC and turns it into a very powerful and economical machine controller. To run Mach3, you need a PC running the Windows operating system with at least a 1GHz processor with a 1024 x 768 pixel resolution screen. Mach3 and its parallel port driver communicate with the machine hardware through one parallel ports or printer ports. If your computer does not have a parallel port, you can buy a motion controller board from a third-party vendor that uses a USB port or Ethernet for communication. Use of a motion controller board can remove considerable processing load from the computer, so you may want to consider using one to get the performance advantage even if your computer does have a parallel port available. Mach3 generates step pulses and direction signals to perform the steps defined by a GCode part program and sends them to the port or motion controller board. The drivers for your machine's axis motors must accept March3's step pulses and direction signals. Virtually all stepper motor drivers work like this, as do modern DC and AC servo systems with digital encoders. Beware if you are converting an old NC machine whose servos may use resolvers to measure position of the axes as you will have to provide a complete new drive for each axis. To set up a CNC system to use Mach3 software, you must install the Mach3 CNC controller software on your computer, and properly connect your motor drives to the computer's ports.

Mach3 Installation

Computer operating system requirements for parallel port:

1. Desktop PC (Laptops are not supported) with at least one parallel port.

2. 32-bit version of Windows 2000, Windows XP, Windows Vista, or Windows 7. (64-bit versions will not be supported)

3. 1Ghz CPU, 512MB RAM.

4. Non-integrated Video Card with 32MB RAM. (Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)

Computer operating system requirements with an external motion device:

1. An external motion controller. (USB UC100, or Ethernet Smooth Stepper, etc.)

2. Desktop or Laptop with Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10.

3. 1Ghz CPU, 512MB RAM.

4. Video Card with 32MB RAM. (Large G-code files, especially 3D files will require a video card with 512MB RAM or higher)

If you already have an old version of Mach3 installed on your computer, you can install the new version on top of it. You do not need to uninstall the old version first.

1. Turn off the PC, the CNC machine tool, and its drives. 

2. Switch the PC back on.

3. Run the Mach3 CNC software installation package.

When you run the downloaded file, you will be guided through the usual installation steps for a windows program such as accepting the license conditions and selecting the folder for Mach3. STYLECNC recommends that you allow Mach3 to use its default installation folder "C:\Mach3". You will be asked if you want to install various program components, as shown in Figure 1:

4. Select program components screen.

Select Program Components Screen


When you have selected the components you want, click the Next button. The installation procedure will ask if you want to create a custom profile, as shown in Figure 2:

5. Create a custom profile screen.

Create a Custom Profile Screen

Figure 2

For example, If you click the "Mill Profile" button, the screen shown in Figure 3 appears. Of course, you should choose the right profile button for your CNC machine tool. 

6. Create "Mill Profile".

Create Mill Profile

Figure 3

Enter the name you want to assign to the profile and click the "OK" button. If you want, you can create several different profiles. When you have created your custom profile, click the "Next" button.

7. Vital reboot.

You must reboot Windows before running Mach3 software. This reboot is vital. If you do not do it, you will get into great difficulties which can only be overcome by using the "Windows Control Panel" to uninstall the driver manually. So please reboot now.

8. Testing Mach3 installation with your CNC machine.

Up to now, Mach3 CNC controller software is installed, we hope you can enjoy this software with your CNC machine tool.
