Base-plate Layer-height Modifier

The Base-plate Layer-height Modifier writes a variable-layer configuration into the generated 3MF. The plain base uses a coarser layer height while the coloured artwork keeps its original fine layers. It reduces base printing time without changing the entire model to coarse layers.

Written values

The base-plate layer height is half the nozzle diameter:

Nozzle	Base-plate layer height
0.2 mm	0.1 mm
0.4 mm	0.2 mm

Lumina Studio writes the range to the 3MF layer_config_ranges data. A compatible slicer can then apply separate layer heights to the base and coloured region of the same object.

Scope

• The modifier currently applies to Bambu-family slicer output, so it is hidden for other slicers.
• Double-sided models require controlled structure and colour order on both faces, so generation skips the modifier.
• Changing the switch or nozzle size requires a new 3MF generation.

This setting optimises base-plate time; it is not a universal layer-height recommendation. Always inspect the sliced base, materials, and print quality before sending the job.
