Where a calibration value lands
A picked calibration profile's seven values do not all write to the same kind of key when Converting a file. Some are per-filament physics that land in whatever key the target actually reads; a few have nowhere to go on some targets at all, and are named as skipped instead.
Where retraction lands
Retraction length and speed are per-filament physics, so they land in the
slot the target slicer actually reads: Bambu Studio, OrcaSlicer and Creality
Print in filament_retraction_length, PrusaSlicer in
filament_retract_length, Cura in retraction_amount on that slot's own
extruder. None of them go to the printer's own retraction key, so a filament
preset the target resolves later cannot override your measured number.
Where flow ratio lands
Flow ratio does the same, and on Cura it goes further. Cura's per-feature
flows, skin_material_flow and the rest, are literal numbers that follow
material_flow by their own formula rather than reading it live, so a
calibration scales every one of them by the same ratio. Converting an
AnkerMake M5 file (skin_material_flow 97) with a flow ratio of 0.95 writes
material_flow 95 and skin_material_flow 92.15.
What calibration cannot reach
Pressure advance has nowhere to go on Bambu Studio, PrusaSlicer or Ultimaker Cura: none of the three read a pressure-advance key from the file. The Notes table names the skip instead of writing a number nothing reads:
Pressure advance · 0.04 · skipped · Set it on the printer, not in PrusaSlicer
Max volumetric flow works the same way on Cura, which has no such limit:
Max volumetric flow · 12 mm³/s · skipped · Ultimaker Cura has no volumetric flow limit
Every skipped value is a row like these, never a silent drop. The same value skipped on several filament slots is still one row.
