| | Possible Cause | Solution | | :--- | :--- | :--- | | Post-processor not visible in WorkNC | Incorrect entry in wncpos.lis file | Re-check the syntax of the line you added. Ensure it matches the format used for other post-processors in the file. | | "Error opening post-processor file" | WorkNC cannot find the file path | Make sure the post-processor file is correctly placed in the pospro folder and that the filename in the wncpos.lis entry is exact. | | Generated code has incorrect syntax | Post-processor is not compatible with your machine's controller | Verify you are using the correct post-processor for your specific controller (e.g., FANUC, Siemens, Heidenhain). You may need a more specialized version. | | Default parameters are not working | WorkNC is using a different configuration file | Ensure you have copied the postproinfo.cfg file to the correct clientinstsite location and that its settings are correctly uncommented and saved. |

Every CNC machine has unique physical limits, axis configurations, and firmware versions. A generic post processor may output a command that drives a spindle directly into the machine table or fixture.
However, understanding the file structure, configuration options, and common troubleshooting steps is just as important as the file itself. Whether you're placing a FANUC.dat file into your pospro folder or editing the postproinfo.cfg to set default coolants, this knowledge empowers you to take full control of the CAM-to-CNC pipeline.
In your WorkNC installation directory (e.g., D:\WorkNC24\ ), there is a folder typically named pospro . This is where all the post processor configuration files are stored. Once you have securely obtained your authorized post
While the temptation to find a quick "WorkNC post processor download full" on a forum is high, the potential cost of a machine crash far outweighs the price of a legitimate, verified file. For the safety of your equipment and the quality of your parts, always source your post processors through or certified partners.
: You might find shared post-processor files on third-party websites and CNC programming forums. For example, you can find a standard FANUC 3-axis post-processor that can be downloaded as a .dat file. In another example, a standard FANUC 3-axis post-processor can be downloaded for free, with the author offering to customize it.
The post is configured for a different machine kinematics. Solution: This requires editing the Machine Base matrix. In the Post Manager, go to Configuration > Axis Mapping . Reverse the sign for the rotary axis (e.g., change +C to -C ). | | "Error opening post-processor file" | WorkNC
