Removed, with the keys added to handle_legacy()'s ignore list so saved
profiles and 3MFs keep loading:
- belt_slice_rotation_global and preslice_remap_global. Both were only
consulted when belt_preslice_global ("Global mesh transforms") was off,
which no profile does; belt_preslice_global is now the single global
mode and is presumed on everywhere the old flags were ORed in
(PrintObjectSlice, BeltBackTransform, BeltGCode, Print::process,
PrintApply). The Belt tilt row is axis + angle only.
- preslice_remap_x/y/z. No profile used the pre-slice axis remap; the belt
tilt axis plus the G-code axis remap cover the machines that exist, and
its implementation only agreed with itself for a plain swap (matrix
columns vs remap_bbox rows). BeltTransformPipeline::build_preslice_remap,
remap_bbox and has_preslice_remap are gone, the forward transform is the
rotation, and the G-code header no longer carries the remap.
- belt_support_z_offset_mode. Saved and invalidated steps, but no support
generator read it.
- first_layer_plane and first_layer_plane_offset, with FirstLayerPlane.cpp.
On every shipped configuration the band is measured from the belt
surface (GCode::belt_height_above_floor) and the evaluator was only
reached for an explicit XY/YZ/XZ choice or a non-zero offset, which
nobody set. first_layer_plane_thickness stays as the band unit,
relabelled "First layer band thickness".
UI: the Machine frame transforms group is five single-option rows (G-code
remap X / Y / Z, Decouple machine-frame tilt, Machine-frame tilt angle;
the angle row is shown only when decoupled) instead of two multi-column
lines, and the remap fields carry full labels.
Also carries the phong.fs struct fix from #16226 so the worktree build
links its shaders.
libslic3r_tests and fff_print_tests pass; clang-tidy diff check clean;
orca_profile_tool.py check clean.

main's profile checks reject the belt bundles: their filaments override
variant keys with one value under the library's six-variant presets, the
copied vendor commons carry keys the slicer no longer reads, the IR3 V2
and BabyBelt Pro machine limits miss the silent-mode entry, and the Custom
belt base pins printer_extruder_id to one entry under a three-variant list.
- The BabyBelt Pro and IR3 V2 filaments name the one extruder variant
their printers have, as the other vendors' filaments built on the
library do, and drop every override that only repeats the library value
(diameter, density, temperature range, most of the fan settings...).
The eSUN filaments inherit the narrowed list.
- The Custom belt base inherits printer_extruder_id from its base.
- normalize drops silent_mode, adaptive_layer_height and
tree_support_with_infill; fix-variant gives the machine limits their
silent-mode entry, which they read from the single value before.
- The IR3 V2 drops two limits equal to its base in both modes.
- Custom's index is regenerated and all three vendor versions bumped.
Flattening every belt preset before and after, nothing a belt printer
reads changes: printer_extruder_id is one id per variant, all 1.
Printcepts and IdeaFormer keep their own machine and process bases: only
filaments can inherit across vendor bundles (from OrcaFilamentLibrary), so
they cannot build on the Custom belt printer.
On a belt printer a lift is a move along the belt axis (0.4 mm / sin 45 =
0.57 mm of belt travel out and back on every hop), not a lift away from the
part. The three belt printer bases now ship z_hop 0, the IR3 V2 leaf no
longer restates 0.4, and the BabyBelt Pro and IR3 V2 filaments stop
overriding the printer with filament_z_hop 0.4. The option stays editable.
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).
The IdeaFormer IR3 V2 End G-code ran `G28 ; home all`, which homes the
Z (belt) and Y (gantry) axes. On a belt printer Z is the conveyor, so
homing it runs the belt all the way back to origin, dragging the finished
part back under the gantry that G28 has just lowered — the head knocks the
print (reported by an IR3 V2 user; the `G1 Y50` lift came after the G28,
too late).
Replace the end sequence with a belt-safe one: switch to relative mode
(G91), lift the gantry for clearance, advance the belt forward one full
machine-depth (Z676, the 676 mm product depth) to eject the part and cycle
the belt surface clean, then home X only — never the Z/belt axis.
* Add IdeaFormer IR3 V2 belt printer profile
Self-contained vendor profile for the IdeaFormer IR3 V2 (45 deg belt printer):
machine (0.4 nozzle) + 0.20mm process + Generic PLA/PETG filaments, with the
belt machine-frame transforms set explicitly on the machine preset
(belt_printer, belt_slice_rotation x/45/global, build_plate_tilt_x=45,
gcode_remap_x/y/z, gcode_shear_z=pos_tan, gcode_scale_y=inv_cos).
The vendor bundles its own machine/process commons (fdm_belt_common,
fdm_klipper_common, fdm_machine_common, fdm_process_common) on purpose:
OrcaSlicer resolves system-preset inheritance per-vendor, so a profile that
inherits the Custom vendor's commons cross-vendor fails to resolve its parent
and the whole IdeaFormer vendor silently fails to load. Bundling the commons
(and listing them in IdeaFormer.json in dependency order) keeps the vendor
self-contained, matching how every other vendor folder is structured.
Machine limits, bed temperature (75 C for belt PLA) and start/end G-code are
taken from a working IdeaFormer IR3 V2.
* feat(belt/profile): eSUN PLA @IdeaFormer IR3 V2 — HW-calibrated belt filament
Add an eSUN PLA belt profile for the IR3 V2, inheriting Generic PLA @IdeaFormer
IR3 V2 (self-contained: parent is in the same IdeaFormer vendor, registered
after it in filament_list). HW-calibrated on the IR3 V2:
- nozzle_temperature 200/200 (temp-tower calibration)
- pressure_advance 0.12 (PA calibration)
- filament_max_volumetric_speed 10 mm³/s (max-vol-speed calibration: wall
failed at 126 mm/s → 126 × 0.0798 mm³/mm ≈ 10 mm³/s)
