How do I select a different post?

For most users, selecting a post processor in Mastercam X is similar to Version 9. The major difference is that instead of selecting the .pst file directly, you need to select the machine definition that has been configured for the post processor. You can do this before creating your toolpaths:
Selecting a machine before creating toolpaths

or after your toolpaths have been created, through the machine group properties in the Toolpath Manager:

The following procedure shows how to select a different post processor for toolpaths that have already been created. Some shops might be configured so that each machine definition has multiple posts. In that case, follow these steps instead.

Selecting a different post processor

This procedure applies to typical users whose machine definitions are set up to allow only a single control definition and post processor. In this case, you will select the new post processor by loading a different machine definition.
  1. In the Toolpath Manager, click the Files icon in the machine group.
  2. Click the Replace button in the Machine section.

    3. Click this button to replace the machine definition.
  3. Select the machine definition which contains the desired post.
  4. Mastercam displays the name of the new machine definition with the new post processor.

    5. The new post is displayed in the machine group properties.
  5. Click OK to close the Machine Group Properties dialog box.

Selecting a different post processor — machines with multiple post processors

If your shop uses machine definitions that have been configured to support multiple posts, follow these steps to use a different post processor for the current job. The new post selection will be saved as part of the machine group properties so that when you post toolpaths from this machine group in the future, the new post will be used, but it does not affect other parts or Mastercam files.

  1. In the Toolpath Manager, click the Files icon in the machine group.
  2. Click the Edit button in the Machine section.

    3. Mastercam opens the Machine Definition Manager.

  3. Select the new post processor from the list.

    4. Selecting the new post

    The list displays all of the post processors that have been configured for the current machine. If the post that you want to use is not listed here, either select a different machine definition (see previous page), or it needs to be added to the list. See the MD/CD Toolkit or the online help to learn how to do this.

  4. Click Yes when Mastercam asks you if you want to replace the existing control definition.
  5. Click OK to close the Machine Definition Manager. Mastercam should then display the name of the new post:

    6. The new post is displayed in the machine group properties.
  6. Click OK to close the Machine Group Properties dialog box.
