Physical max-volumetric-speed test (belt #62 v4 asset) on the IR3 V2 with eSUN
PLA white: the wall stayed clean up to ~100 mm/s = ~20 mm3/s before
under-extrusion. The shipped cap of 10 mm3/s was ~half the real ceiling and
was silently throttling infill.
- eSUN PLA @IdeaFormer IR3 V2: filament_max_volumetric_speed 10 -> 20
- 0.20mm Standard @IdeaFormer IR3 V2: sparse_infill_speed 200 (~18 mm3/s at the
new cap, no longer throttled). Outer wall (45), PA (0.12), accel (1000)
unchanged — accuracy preserved.
- IdeaFormer.json version bump for profile-cache refresh.

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)
