nx_material_profile.nx

nx_material_profile.nx -- data-driven filament profile: temps, speeds, cooling, retraction, pressure advance, bridging. Per cardinal NISHI_3D_PRINT_ROADMAP §2.11 + Cardinal 11: every material-specific value lives here, parameterized. No "magic 215°C" in the slicer. Material registry is operator-owned per cardinal feedback-user-owns-every-bit; future nx_calibrate (P5) will derive operator-specific overrides from a 10-minute auto- calibration print. Per cardinal feedback-bits-up-exceed-never-match: material profiles are content-addressed by BLAKE2b hash so peer operators can share + verify profiles without trust. G-code header carries the profile hash (via nx_gcode_manifest) -- a failed print maps back to the exact profile used. Unit conventions per field: - Temperatures: integer °C - Speeds: integer mm/s - Retraction distance: integer µm - Percentages: integer 0..100 - Q14 fixed-point: flow ratios, pressure advance (small fractional values where precision matters and a percentage is too coarse) SEED profile = nx_material_profile_generic_pla() conservative defaults appropriate for a first proof print on Christus. These values target SUCCESS over speed; nx_calibrate (P5) will derive operator-tuned values once the printer has been profiled. license_tier: ORIGINAL
