Nestor Settings
The nestor controls how WSi arranges parts on a sheet during nesting — the process of finding the optimal placement for each part to minimise material waste.
Open via Settings → Client → Nestor settings.
Nestor settings affect all sheet nesting operations: Laser Sheet Cutting, Plasma Sheet Cutting, and Waterjet Sheet Cutting.
Sheet Nesting
| Setting | What it does |
|---|---|
| Nesting distance | Minimum gap in millimetres between adjacent parts on the sheet |
| Nesting mode | How parts are grouped during nesting — see below |
| Upper side strategy | Which face of the sheet is considered "up" for asymmetric materials or coatings |
| Scrap area threshold | Minimum scrap area in mm² before WSi flags it as waste |
Nesting Modes
| Mode | Description |
|---|---|
| Actual Individual | Each part is nested individually. Higher quality but uses more sheet. |
| Actual Mixed | Multiple parts are mixed on the same sheet to reduce waste. |
| Virtual Individual | Parts are placed as individual but share a common outer boundary. |
Tube Nesting
| Setting | What it does |
|---|---|
| Nesting distance | Minimum gap between tube parts during nesting |
| Nesting mode | How tube parts are arranged on the stock length |
TIP
A smaller nesting distance reduces waste but increases the risk of parts being too close together for cutting. Check your cutting machine's minimum clearance requirements before setting a tight distance.
