One-pass posting

Swiss posts use a different posting order called one-pass posting. In multi-pass posting, used by other standard posts, all the operations on a tool post are posted in order before moving on to the next tool post. In one-pass posting, all operations on all tool posts up to the next sync point are posted. While the operations are still posted in the order they occur, it is not guaranteed which tool post will be posted first.

To enable one-pass posting, select CNC-Info > Tool Posts to display the Tool Post Information dialog, and select One pass posting.

The following diagram shows the one-pass posting order, including where important system formats are called. The blocks are labeled alphabetically in the order in which they occur.

• Blocks with more than one letter indicate that the posting order is undefined.
• In the first control group, block C could also be posted after D and E.
• Similarly, block I could also be posted before G and H.
• Sync Point B is called even if there is no user-specified sync point. Use <LINE-IS-SYNCED> to decide whether to output a wait code.
