Bambu Studio Layer G-code#

What Was Established#

Methods for applying custom G-code to specific layers in Bambu Studio, including Height Range Modifiers and the Layer Range G-code interface. Specific commands for Bambu Lab printers to control infill angles, wall order, and layer pauses.

Key Decisions#

Layer Range G-code Interface: Preferred for direct layer-specific application without Height Range Modifiers.
Layer Numbering: The Layer Range G-code UI uses 1-indexed layer numbers. Conditional logic ({if layer_num == X}) uses 0-indexed numbers.
Bambu Proprietary G-code: Commands like M9000 (infill angle) and M9001 (wall order) are specific to Bambu Lab firmware.
