Dowel Hole Grid

Drills a rectangular grid of holes across the spoilboard, evenly spaced and centered within the X and Y extent. Drop dowel pins into the holes to square up stock against them, or use them as extra anchor points to hold material down.

Each hole is a single straight plunge to the pen-down Z level and back up to clearance height — sized only by whatever the bit cuts, with no pocketing or peck drilling. Set Hole Spacing X/Y to the exact pitch you want between holes; as many holes as fit are placed at that spacing, with any leftover space split evenly as margin on both sides so the grid is centered within the extent.
