Hole & Ring Naming

Production prefix

Reamer prefix

Ring prefix

Hole start no.

A ring is a row of one or more holes at the same height. Ring 1 is the top row, numbering downwards. Holes number left to right within each ring, restarting from the start number on every ring — so the same hole name can repeat in different rings. Production and reamers share one counter per ring (the number just increments; the prefix marks the type), e.g. P1 P2 R3 P4.

Firing Sequence & Timing

First hole delay (ms)

Start timing from hole no.

Interval between holes, per stage (ms)

Each hole's gap from the one before is its own stage's interval — so holes in the same stage step by the same amount, and each stage can run at its own timing.

Timing starts at the hole number above: earlier holes keep the delay you typed, and the run continues from the last of them. Starting at hole 1 uses the first-hole delay. Reamers are uncharged, so they get no firing number or delay. Set any hole's timing individually in the Selected Hole card.
