The x32 default landed in forgetest/baseline.py and the driver, but two
callers still judged the machine at x8 and both failed on the host.
forgetest/tests/test_baseline.py: setUp seeded the fake machine from the x8
FIXED_SYSFS literals while enforce() compares against fixed_sysfs() of the
resolved mode, so x_mode, y_mode, step_freq and ramp_rate read as deviations
on a clean machine - 23 failures across BaselineTests and
TransientNotLeftoverTests. It seeds from fixed_sysfs() now, and the tick
expectations come from it (DEFAULT_TICK) rather than a typed 28160. The
xy_mode_of and ref_xy_mode unset/invalid cases expect 32, with an explicit
"8" case added that had no coverage. Two reference_preconfig dumps taken on
an x8 machine carry xy_microsteps = 8, because the markers are read at the
reference's own mode. wait_configured wrote the static CONFIGURED_MARKERS
where the function watches configured_markers() of the mode in force, and
the held-controller jog typed 221 steps for "4.144 mm", which is 1.036 mm at
x32; both derive from the mode now. 69 tests, all pass.
scripts/bench/laser_stream_test.py: STEPS_PER_MM was the x8 53.333, so the
X-peak check failed at 2133 steps against an expected 533. The whole harness
now derives from XY_MICROSTEPS_BASE/DEFAULT the way glowforge.h and
baseline.py do, which uncovered five more x8-only expectations behind the
first: the machine tick, the fire-gap limit (it grows as sqrt(k), not k - a
finer mode shortens the accel interval by sqrt(k) while speeding the tick by
k), the rung split in fire_spans, the density period and minimum burst
(laser_pulse_ticks is in x8 ticks and the stream scales it, so the config
keeps the x8 numbers and the measured lengths scale), and the decel/hold
budgets. Run against the null-sink build: all stream emission rules hold.
xy_mode_test.py's docstring still described the no-key case as x8 while its
own assertions had moved to x32.
No behavior change and no acceptance-catalog consequence: these are test
expectations and a bench harness, not image component sources. The coverage
lint is unchanged at 0 uncovered paths.
Acceptance baseline: XY_MODE_DEFAULT 8 -> 32, split out XY_MODE_BASE (8) for
the tick/ramp scaling, matching the driver. The mode-aware comparisons
(fixed_sysfs of the resolved mode) judge an unset machine at x32.
Host CI: xy_mode_test.py default and invalid cases expect x32/213.333/112640.
Bench tools: raster_dry.py and xy_pattern_accel.py set_mode() cleared the key
for mode 8, which relied on clear == the x8 default; clearing now yields x32,
so they set the mode explicitly and restore to x32. live_fire_drills
STREAM_RATE_HZ is the 28160 Hz laser reference tick, the same at every mode.
The baseline derives x/y_mode, step_freq, ramp_rate and the configured
markers from the xy_microsteps setting; ramp_rate joins the GRBL
controller's set (the driver writes it; the cloud client runs at the
module's). motion.microstep-modes cycles 8, 16 and 32: the save restarts
the idle controller, the kernel reads the mode with its tick and ramp,
$100/$101 are the mode's and a typed $100 is overwritten, a 40 mm jog at
top speed returns to Idle with the kernel counters over the mode agreeing
with the commanded travel and the accelerometer seeing the head move; the
setting is put back as found.
Bench tools: xy_mode_test.py (the null-sink harness the grblHAL CI runs),
raster_dry.py (a top-speed raster per mode), xy_pattern_accel.py (the
operator's pattern from home with the machine silent and the head
accelerometer listening), arc_tolerance_sweep.py (a $12 ladder on the 9
in circle: the chord rate the protocol loop feeds, about 300 a second, is
the ceiling, not the core), and the xymode and xycircle live drills.
BRINGUP carries the present state and the facts; CAMPAIGN-LOG the dated
record, including the planner-blocks spin (a $398 of 255 or more loops
forever at start, a core bug) and its recovery.
