Users working with PEPS Wire programming may occasionally encounter difficulties when attempting to configure multiple extra tags within a single program. A common scenario involves having two holding tags where the software restricts the ability to modify the start point for the tag. This limitation can disrupt workflow efficiency and lead to confusion regarding the correct setup procedure for complex wire EDM operations.
When a user reports that they cannot change the start point on the second of two holding tags, the root cause often lies in the configuration of the post-processor or the integrity of the underlying geometry. The software relies on specific command prompts to define the lead-in position and the start position for extra tags. If these parameters are not correctly recognized, the interface may lock certain fields, allowing modification on only one tag while leaving the other static.
To address this, it is essential to utilize the improved extra tags functionality available within the post-processor configurations. This feature is designed to provide granular control over both the lead-in position and the start position for every extra tag in the sequence. By accessing the post-processor settings, users can ensure that the command prompts are active and correctly mapped to the geometry. When the system is properly configured, the user should be able to follow the on-screen prompts to select the specific positions for each tag independently, thereby resolving the issue where only one tag was editable.
In many instances where the extra tags fail to behave as expected, the underlying issue is not a software limitation but rather a problem with the geometric data itself. Duplicate geometry or corrupted figures can prevent the software from correctly calculating the figure required for the extra tags. When the figure is not generated correctly, the system may not act as expected.
To resolve geometry-related conflicts, users should perform a systematic cleanup of the wireframe data. The first step involves removing the existing wireframe to see the figure. Following this, the figure should be exploded using the "Figure Explode" option found within the Layers/Figures menu. This action breaks the figure down into lines and arcs, making it easier to identify and remove redundant data.
Once the figure is exploded, the user should navigate to the Modify Tab and utilize the "Delete Duplicates" function. It is crucial to select the "Delete All" option during this process to ensure that every instance of duplicate geometry is removed. This step is vital because even a single overlapping line or point can cause the figure generation logic to fail, resulting in the inability to set start points for all tags.
After cleaning the geometry, the final step to ensure full functionality is to rebuild the figure from scratch. Before creating a new figure, it is necessary to delete any residual shapes, such as squares or circles, that were part of the old figure used for the extra tags. These remnants can interfere with the new figure generation process.
With the workspace cleared of duplicates and old shapes, the user can create a new figure and re-apply the extra tags. This fresh approach ensures that the software calculates the path and start points based on clean, non-redundant data. Once the new figure is established, it should be added to the Standard Profile Machining configuration.
To prevent these issues from recurring and to maintain a smooth programming workflow, users should adopt a proactive approach to geometry management. Regularly checking for duplicate entities before applying complex features like extra tags can save significant time. If the standard cleanup procedures do not resolve the issue, users should verify their post-processor configurations to ensure the improved extra tags feature is enabled.
For persistent problems that cannot be resolved through these steps, it is advisable to gather the relevant project files, specifically the .vdm file, and seek further assistance. Providing the file allows for a detailed analysis of the specific geometry and configuration settings, ensuring that any unique edge cases are addressed effectively. By following these structured steps—configuring the post-processor, cleaning duplicate geometry, and rebuilding figures—users can confidently manage multiple extra tags and achieve precise control over their wire EDM programs.
