Move the actual post file (usually .PST or .PSB for encrypted posts) into the Posts subfolder of your specific machine type (Mill, Lathe, Router, or Wire). Select the Machine in Mastercam: Open Mastercam. Go to the Machine tab on the ribbon.
Some popular Mastercam post processors include:
A post processor is a software component that translates the toolpath data generated by Mastercam into a machine-specific code, known as G-code. This code is then used to control the CNC machine, instructing it on how to move the cutting tools to create the desired part. Post processors are specific to each CNC machine and are designed to optimize the machining process, taking into account factors such as machine capabilities, tooling, and material properties.

In computer-aided manufacturing (CAM), your choice of software is only half of the equation. You can design the most efficient, precise toolpath in Mastercam, but if your CNC machine cannot interpret that data, your production stalls. This is w
A Mastercam post processor acts as a universal translator, converting your digital toolpath data (NCI files) into the specific G-code and M-code language required by your unique CNC machine controller. Finding, downloading, and configuring the right post processor is essential for achieving safety, precision, and peak efficiency on the shop floor.

Treating your post processors as a vital component of your manufacturing toolkit—rather than an afterthought—directly correlates with shop floor success. By avoiding risky, unverified downloads and relying instead on the Mastercam Tech Exchange, authorized resellers, and factory-certified OEM packages, you safeguard your hardware and optimize your cycle times. A reliable, well-tuned post processor ensures that the precision engineered inside your Mastercam software transfers flawlessly to the physical part on your machine bed.
Copy the .mmd-x file into the CNC_MACHINES folder.
Once you have obtained the correct post processor file from an official source, the installation process is generally straightforward. Mastercam post-processors are delivered in two main formats: the modern .mcam-content package and a traditional .ZIP file. Go to the Machine tab on the ribbon
The reality of the "download" culture is that
Mastercam installation includes generic posts for common controls (Fanuc, Haas, etc.). These are a good starting point but often require modification.
