The belt-printer branch is failing two profile gates. Both stem from the
three belt-only vendors (Custom's generic belt printer, IdeaFormer,
Printcepts) not existing upstream, so upstream maintenance passed them
by.
Slice check: 4 of 1015 printers failed - Custom's MyBeltPrinter 0.2/0.4/
0.6/0.8 nozzle all fell back to "Default Setting". No process profile in
the Custom vendor listed any MyBeltPrinter in compatible_printers, and
Custom's fdm_belt_common pointed default_print_profile at "0.20mm
Standard @System", which does not exist in that vendor's index, so the
generic belt printer had no usable process at all. This gap dates to
when MyBeltPrinter was added (2026-04-07); it only started failing now
because the slice-check job is newer than that.
Adds two process profiles modelled on the sibling @MyKlipper ones:
- 0.20mm Standard @MyBeltPrinter - 0.4/0.6/0.8 nozzles
- 0.12mm Fine @MyBeltPrinter - 0.2/0.4 nozzles
The split is forced by hardware: the 0.2 nozzle preset caps
max_layer_height at 0.16, so a single 0.20mm profile cannot legally
cover
it. fdm_belt_common now defaults to the standard profile and the 0.2
nozzle preset overrides to the fine one.
setting_id: 14 files failed the rules introduced in #14432. That
migration renumbered 7425 files across 61 vendors but skipped these
three, leaving BabyBelt Pro, IdeaFormer IR3 V2 and MyBeltPrinter
squatting the "G*" id space reserved for Bambu (GMPC0BBP01, GMIF001,
GM_BELT_00x) and four instantiated filament/process presets carrying no
setting_id at all. Regenerated with
scripts/assign_vendor_setting_ids.py.
Also repoints the identical dangling "0.20mm Standard @System" in
Printcepts' and IdeaFormer's fdm_belt_common at their own real process
profiles. That is a no-op today because both concrete printers override
it, but it is the same landmine that took out MyBeltPrinter.
Vendor index versions bumped so check_installed_vendor_profiles() will
re-install the corrected profiles over an existing install.
Note: changing a shipped preset's setting_id can orphan user presets
that reference it as base_id. #14432 accepted that tradeoff for 61
vendors; this keeps these three consistent with the rest.
Verified: orca_extra_profile_check.py reports 0 errors across 66 vendors
(was 14 files with errors), and OrcaSlicer_profile_validator -s slices
all 1015 printer presets successfully (was 4 failures).

Enables supported printing of standard Orcaslicer calibration profiles.
* Build 2 Checkpoint
* fix support generation wedge, ghost layers
* flip cornering tests 180 deg to waste less supports
* fix row spacing on the flow ratio calibrations
* more testing, this didn't fix anything
* switched rotation tools, same issue
* fixed Z-offset issues
* add rest of PA features, may look a bit weird on a belt
* make temp towers work
* re-enable spiral on calibrations that want it
* Final cleanup pre-PR and community testing
* fix: restore BuildVolume bounds when toggling belt mode
set_belt_printer() mutated m_bboxf when enabling but never restored
the original extents on disable or when switching infinite_y true->false,
leaving stale max.y/max.z values that broke collision and object_state
checks. Recompute m_bboxf from m_bed_shape + m_max_print_height at the
top of each call, then apply belt-specific adjustments on top.

* chore: drop [BELT-DEBUG] to_machine_coords log to trace
Was emitting at warning level once per 0.2mm Z bucket during every belt
print export, polluting default user logs. Trace level matches the rest
of the belt diagnostics and is silent in production.
Addresses Copilot review comment on PR #12998 (BeltGCodeWriter.cpp:86).
* chore: drop [BELTRACE] make_perimeters/support logs to trace
Eight warning-level traces around make_perimeters and
generate_support_material were emitting on every call/exit during normal
slicing, cluttering default logs. They're concurrency-debug breadcrumbs
not user-facing diagnostics, so drop them to trace.
Addresses Copilot review comment on PR #12998 (PrintObject.cpp:438).
* perf: gate BeltSliceStrategy diagnostic bbox tracking behind compile flag
apply_to_trafo() walked every model vertex twice (once for min_z, once
for per-volume mesh/slicer bboxes) and emitted seven trace logs per
call. The bboxes and logs are diagnostic only; min_z is the load-bearing
output. Wrap the bbox accumulation, logging, and supporting headers in
SLIC3R_BELT_DIAGNOSTIC_LOG so production builds do the bare min_z scan.
Addresses Copilot review comment on PR #12998 (BeltSliceStrategy.cpp:95).
* fix: apply part_cooling_fan_min_pwm to first-layer plane fan crossings
apply_first_layer_plane_fan_eval emitted band-crossing M106 commands
through GCodeWriter::set_fan() without the per-printer PWM floor that
every other set_fan call in CoolingBuffer applies. On printers with a
non-zero part_cooling_fan_min_pwm, fans could fail to spin up at low
requested speeds near the belt surface.
