- IQEX (0.4/0.6/0.8): retract_restart_extra_toolchange 1 -> 0 on all four
tools. With the silicone ooze blockers the parked nozzle stays primed,
so an extra 1 mm after each toolchange can over-extrude at the restart.
- Add 0.04mm Ultra Fine and 0.08mm Extra Fine @Xplorer 0.4 on the existing
fdm_process_xplorer_common ladder for all four 0.4 printers. Same speeds,
accelerations and line widths as the 0.12mm Fine tier; only the layer
height, shell layers, bottom_shell_thickness 0.6 and (0.04) top solid
infill flow differ. Support stays off, as on the other tiers.
- Xplorer_buildplate_model.stl: decimated from 82,508 to 10,000 triangles
(4.1 MB -> 500 KB). Same bounding box and origin, so bed_model is unchanged.
- Covers: one distinct 240x240 image per model instead of the same image
copied four times (39 KB each -> about 11 KB each).
The Xplorer ships in four configurations that differ in how many toolheads they
carry and how those heads are arranged: Single, IDEX with two heads on one
gantry, Dual Gantry with one head on each of two, and IQEX with two on each of
two. Each is offered at 0.4, 0.6 and 0.8 mm, giving four machine models, twelve
machines over a shared base, and a five-tier process ladder per nozzle.
The dual-gantry machines park the second gantry's tools over the plate, so the
area both gantries can reach is 57.5 mm shallower than the plate itself. Those
two declare 400 x 342.5 where Single and IDEX declare 400 x 400. That depth is
what the parallel print modes divide into equal zones, so it has to be the
reachable area rather than the physical one.
The bed textures are drawn to match. Texture coordinates are normalised per
axis, so a canvas whose aspect differs from printable_area is stretched and
anything drawn outside the plate is pulled onto it; each viewBox equals its own
model's area. They mark the real reach limits and nothing else, because the
print zones are computed and drawn per plate at run time and a static copy of
them only disagrees with the live one.
Motion limits are the firmware's: 5000 acceleration, 300 mm/s, 100 on Z, 120 on
the extruder, and a square corner velocity of 5 rather than a jerk, which Klipper
does not have. Every per-extruder and per-variant value is written at full width,
because padding a short array repeats its first value rather than its last pair
and would otherwise hand every extruder past the first a normal-mode figure in
its silent slot.
The processes are based on a profile tuned on the hardware. Line widths are
expressed as percentages of the nozzle so one statement serves all three sizes,
and the ladder varies only what belongs to layer height. Extruder variants are
declared rather than left to a default that would have capped volumetric flow at
a figure describing a plain V6.
Verified by slicing all fifteen tiers on all four models: every one completes,
emitted accelerations and widths match what the profiles resolve to, no
coordinate leaves the printable area, and the two pre-existing Troodon models in
the same bundle are unaffected. The bed graphics, the print zones and the
volumetric cap resolve through paths the command line does not exercise and want
confirming in the application. Values tuned against hardware the author does not
have - the 0.8 ladder in particular - are a starting point rather than a result.
