Saving a K-profile was fire-and-forget. set_kprofiles_batch published
and returned True, and the printer's extrusion_cali_set answer was
logged at DEBUG and dropped, so a write the printer refused was
reported to the user as saved (#2718, reporter @jmoore-skild).
The reason it could not simply be gated on: the answer itself was
wrong. Single-nozzle firmware returned result:"fail" with
reason:"invalid tray_id" on writes that demonstrably applied.
Measured against an X1C and an H2D over MQTT, the cause is the
tray_id:-1 Bambuddy itself put in the payload. Sending three
otherwise identical writes isolated it: tray_id:-1 fails, tray_id:0
succeeds, and cali_idx:-1 is accepted either way, so only that one
field is at fault. The H2D ignores the value entirely; the X1C
validates it, complains, and applies the write anyway. BambuStudio
always sends a real tray_id and defaults it to 0 for a manually
entered profile.
With tray_id:0 the acknowledgement is honest, and the printer echoes
back the sequence_id we sent -- confirmed for extrusion_cali_get,
_set and _del on both printer classes -- so it can be matched to the
write that caused it. Writes now return their sequence_id and the
routes await the verdict, turning a real failure into an error that
carries the printer's own reason. A printer that stays silent is
still treated as success: no answer is not evidence of refusal, and
firmware that never answers must not turn every save into an error.
Raises the ack to INFO. It sat at DEBUG, so the one line that
explains a failed save was absent from every support bundle -- the
same reasoning that put ams_filament_drying at INFO for #1447.
Also fixes extrusion_cali_set building its payload from
str(self._sequence_id) without incrementing first, reusing the
previous command's id. Harmless while nothing correlated on it,
fatal now that the write path does.
Adds supports_nozzle_flow_type() for the Standard / High Flow choice,
which the K-Profiles UI previously showed as "Not reported by
printer" -- not a value anyone can save. Most printers omit the
nozzle identity from their calibration table entirely, and the slicer
treats that as Standard rather than unknown; Bambuddy now does the
same and keeps the choice editable. The field is hidden only where
the model ships a single nozzle variant, using the slicer's own rule
(len(nozzle_volume) // len(nozzle_diameter) > 1 over the machine
preset) evaluated across every bundled Bambu profile. That puts only
A1, A1 Mini and A2L on the hidden side -- it is not the single-
versus-dual-nozzle split, since P1P, P1S, P2S, X1, X1C, X1E and H2S
are all single-nozzle and all carry two variants. Editing a profile
also no longer writes back an empty nozzle_id.
Wiki records that on printers which omit the field the chosen flow
type is discarded by the firmware and reads back as Standard, in
Bambu Studio as well, so it does not get filed as a bug again.
