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)
