| Control | Effect |
|---|---|
| General source clearance | Contour relief on the actual source: studs, receiving walls and body outlines can change together. |
| XY dimensional fit | A per-side contour correction; positive values expand exterior contours and narrow cavities without scaling the grid. |
| Material shrinkage | Whole-part scale compensation, which also changes stud-center spacing. |
| 4.80 mm receiving relief | Local underside fit change with the gripping stud diameter and stud-center grid fixed. |
| Experimental interlock projection | Local contact target scoped to its geometry revision; v2/v3 account for receiving gaps, while v1 retains its added-pad-depth meaning. |
| Precision v3 body clearance | A fixed exterior-body inset in the rebuilt mesh; the stud grid and receiving planes stay fixed. This is separate from global XY correction. |
In general clearance comparisons, lower or negative clearance tightens the connection. Positive XY can also tighten it, but changes the outer body dimensions at the same time. These settings should not be used interchangeably.
In fixed 4.80 mm mode, receiving relief is the only fit variable. More negative relief adds contact material underneath; more positive relief opens the receiver. Do not interpret −0.020 mm as the stud diameter or paste a historical MachineBlocks offset into this field.
In Interlock lab, larger positive projection targets more local receiving contact. V2/v3 measure receiving gaps and target net contact interference; its value is not necessarily the total added thickness. Original v1 keeps its added-pad-depth meaning. Zero adds no receiving lands and remains the selected design’s smooth-stud control. Keep the geometry revision with the value and do not copy a signed receiving-relief offset into this field.
Nexlock exports the prepared geometry after its selected fit adjustments. Adding the same global XY or shrink correction again in the slicer can double the dimensional change. Native fixed-stud handoff keeps those global compensation values at zero.
First-layer widening, corner extrusion and warping are process problems that can obstruct a good connection. Inspect the cooled loose pieces before changing the whole geometry to compensate for a localized defect.
