Finding the right GibbsCAM post processor (often a .pst, .mdd, or .vmm file package) is essential for turning CAM toolpaths into accurate CNC code. Where to Find GibbsCAM Post Processors (Download/Request)
Local Reseller (Best Source): Contact your local authorized GibbsCAM reseller. They have access to the largest library of post-processors and can customize them to your specific machine, control, and NC code preferences.
Post Haste (Free Alternative): PostHASTE is a third-party, customizable post-processor that acts as an alternative to traditional GibbsCAM posts, allowing you to edit the output directly using a WYSIWYG template. It supports many controls, including FANUC, Siemens, Haas, and Okuma.
Third-Party Services: Companies like CAM Solutions Inc. and Ground Support provide specialized custom post-processors and machine simulation models for complex machines (e.g., 5-axis mills, MillTurns). How to Load a Post Processor (Installation) Save the Package: Download the post-processor ZIP file.
Drag-and-Drop: Open any GibbsCAM window and drag the downloaded ZIP file directly into it.
Confirm Files: A pop-up will show the files (usually including a .mdd and .pst file) being installed to their correct locations.
Important: Always load all files from the zip package, particularly the MDD file, as it defines the machine kinematics. Useful Story: Customizing for Complex Machines gibbscam nc post processor download hot
A common challenge is getting the exact G-code formatting a specific shop needs. According to the GibbsCAM forums, users often struggle with custom formatting like specific tool callouts or coolant commands.
The Solution: Rather than searching for a perfect free download, the best approach is to:
Generate a "Pack and Go" file (.gcpkg) from your part file in GibbsCAM, which compiles the toolpath and model.
Mark up an existing NC code file, highlighting desired changes (e.g., changing M6T1, moving G54, changing coolant M-codes) in a different color.
Email both the Pack and Go file and the marked-up G-code to your reseller to get a specialized post tailored exactly to your needs. To help you find the right post, can you tell me:
What is the Machine Tool Manufacturer (e.g., Haas, Mazak, DMG Mori)? What is the Machine Controller (e.g., Fanuc, Siemens)? Is it a Mill, Lathe, or Multi-Task Machine (MTM)? How to Load a Post Processor File Package Finding the right GibbsCAM post processor (often a
To download and manage GibbsCAM NC Post Processors, users primarily interact with official support channels or specialized libraries, as these files are typically tailored to specific machine-tool combinations. Where to Download Post Processors
Official GibbsCAM Online Portal: You can access current software installers and order forms for new post processors directly from GibbsCAM Online.
CAMCO Resource Library: The CAMCO Support Page provides links for ordering new post processors for milling or turning, as well as instructions for modifying existing ones.
Post Haste (Free Option): A free post-processor utility called Post Haste is often available to GibbsCAM users. It includes a library of hundreds of standard post-processors that allow for basic customization of NC output.
Third-Party Libraries: For specific machine simulation models or custom post-processing needs, third-party services like CAM Solutions Inc. offer specialized configurations. Installation and Modification
How to Load: Drag a downloaded .zip post-processor package directly into an open GibbsCAM window. Clicking "Okay" in the pop-up window will automatically place all necessary files (like .mdd and .post) in their correct locations. Step 3 – Register the Post in GibbsCAM
Modification Requests: To get a post processor edited, users typically need to create a "Pack and Go" file of their part and submit it along with a marked-up NC code file to their local reseller or the post-processing department.
Editing Tools: Editing proprietary GibbsCAM posts often requires specialized software like Compost, which is generally managed by developers rather than end-users due to its complexity. How to Load a Post Processor File Package
| Problem | Likely Cause | Solution |
|---------|--------------|----------|
| Post not showing in list | Wrong folder or missing .gpostcfg | Move files to ProgramData folder, not appdata |
| G-code has wrong G-commands (G70/G71 instead of G41/G42) | Post built for different control | Edit post via PostHaste (GibbsCAM’s post editor) |
| Subprograms / macros missing | Post lacks subprogram support | Request a “full” version from reseller |
| Post processor locked (greyed out) | Needs license key | Contact GibbsCAM reseller |
This is often the "hidden gem." Your local GibbsCAM reseller likely has a private repository of post processors they have customized for other clients in your area. Sending a quick email to your reseller’s support line is often faster than searching the web for hours.
Analyzing search trends and forum activity (CNCzone, Practical Machinist, GibbsCAM official community), a "hot" post exhibits:
| Criterion | Indicator |
|-----------|------------|
| Time sensitivity | User posts “urgent,” “production stopped,” “need today” |
| Specificity | Exact machine model + control + option (e.g., "Haas VF-4 with High Speed Machining") |
| Version lock | Requires GibbsCAM 15.x or 16.x, not generic |
| Modified post | Not factory default – includes custom cycles (rigid tapping, tool breakage detection) |
| File hash sharing | Users share .gpp or .gpi files via direct links, not official channels |
