Mastercam post processors play a vital role in the CNC machining process, ensuring accurate translation of toolpath data into machine-specific code. By following the steps outlined in this article, you can easily download and install Mastercam post processors, optimizing your machining processes and improving productivity. Remember to always use the latest version, verify post processor settings, and test and validate your post processor to get the most out of your Mastercam system.
When you contact your reseller, they will guide you through a process to ensure you get the exact post processor for your machine. This typically involves filling out a Post Processor Request Form, which asks for specific details about your machine's controller, configuration, and the machine's kinematics. Providing accurate information at this stage is vital.
As machine complexity increases, the risk of using unverified downloaded posts rises exponentially. 4-Axis and 5-Axis Milling

No, you should never use a post processor intended for a different machine model or control system. Each post is meticulously configured for a specific machine's kinematics and control software.

The safest and most reliable source for Mastercam post processors is the official . This is Mastercam's official online community and repository where posts are vetted and supported. For users on a valid Mastercam maintenance plan, the Tech Exchange provides access to a vast library of downloadable posts. When you contact your reseller, they will guide
For users who do not wish to edit script directly, many posts are equipped with built-in "switches" that can be used for customization. You can often find these switches within the post file itself, which can be toggled on or off to control certain outputs. For more complex customizations, a common approach is to add lines of code directly within the post. For example, to have an M01 (optional stop) output after every tool change, an experienced user would add a specific code line to the psof$ and ptlchg$ sections of the post file.
Your local Mastercam Reseller (Value-Added Reseller or VAR) is your primary and safest source for post processors.
Older post files (e.g., from Mastercam X9) must be properly updated using the "Update Post" utility before running them in newer versions like Mastercam 2024 or 2026. To help narrow down your search, please let me know: What CNC machine make and model are you using?
