Bump the grblHAL pin to the real-time producer change.
Add motion.step-timing-under-load: the catalog had nothing that
exercised step generation while userspace competed for the single core,
which is exactly the gap that let the condition go unnoticed - the ring
never runs dry, so cnc/underruns reads 0 through it. The test asserts
the producer and the shipper both hold SCHED_FIFO, then drives
2000 mm/min round trips against a deliberate nice-5 CPU hog and requires
the controller to report no clamped events.
Add the pthresh live-fire drill: a constant-power ladder from 2 % to
30 % of full on scrap. Because $35 is a percent of full duty and the
rungs are percents of $30 with $31 = 0, the lowest rung that marks reads
directly as the $35 value. It needs $35 = 0 for the run, or the floor
lifts every rung and hides the threshold.
Record both open items in BRINGUP. The laser one carries the finding
that the factory never uses duty as a power control - all five firing
jobs in the captured pulse files pin the power byte at 127 and modulate
dose by dithering the FIRE bit at 6.5-18.8 % density - so the captures
cannot supply a $35 default, and the duty to optical-power transfer
function of this supply has never been measured.
The remaining bench diagnostics run from forgetest's #bench tab. The
tools that also run from a LAN host share scripts/bench/gfbench.py:
GF_HOST names a remote machine (host mode, sysfs through ssh, Grbl and
forgectrl over the LAN); unset, the tool runs on the board itself
(local mode, sysfs directly, everything on 127.0.0.1), which is how the
page runs them - with GF_HOST=127.0.0.1, the panel token in GF_TOKEN
and their data files under <data>/bench/ (FORGETEST_BENCH_DATA). The
helper also reads a machine setting from forgectrl, or from the settings
file on the board while forgectrl is stopped.
Ported: pwm_sweep / pwm_hold (scope = a takeover; the latch relocked,
the write refused if FIRE or LASER_ON reads active), pwm_stream_test
(PASS/FAIL exit), flow_characterize, flow_recheck_char,
flow_warm_validate and flow_matrix (takeovers: forgectrl owns the
thermal hardware, so the page's takeover replaces the tools' own
controller stop/restart, whose command line predated the supervisor;
results and logs in the bench data directory), flow_sustained,
fan_test, temp_calibrate (dry; watch bounded in seconds; the threshold
and the coolant conversion from the shared code), flow_escalate_drill
(cool_confirm_max_s shortened through forgectrl's settings for the
drill and restored; the setting's minimum is the default budget), and
live_fire_drills (<drill> [S] [F], all six drills, host from GF_HOST,
token from the board). flow_matrix joins the registry. What stays
unported cannot run against the machine at all: the two null-sink CI
harnesses and the .puls decoder.
Runner: a scope tool runs inside the takeover wrapper; the bench
environment above is passed to every tool. Tests: test_bench_registry
(registry <-> scripts/bench consistency, every ported tool builds its
command line, every script compiles, gfbench host/local modes) and the
server test (scope tool takeover, the environment reaching the tool).
Local mode smoke-run on the bench (temp_calibrate watch, setting, token)
from /tmp, removed after.
No catalog consequence: bench tools are not image components (dev-only
forgetest); the acceptance catalog is unchanged.
- platform_drills.py (on the board, forgectrl stopped): dead-man trip
readback, rmmod/modprobe with concurrent attr reads, decay/microstep
readback, LED sequence.
- live_fire_drills.py: ircut (S/F selectable characterization job),
expstop (armed job + POST /controller/stop, controller left stopped),
ctrlstart (separate, operator-approved resume); the token header is sent
in exact case.
- laser_lifecycle_test.py: sigterm-mid-job - SIGTERM during an armed job
must stop it, relock the latch and exit promptly.
Phase 5 A-1 emission witness and A-5 HV telemetry pass on live burns;
A-2 lid-IR characterized as a weak signal at 40% (gate left watch-only);
pgood confirmed unusable as a witness on this PSU. Phase 4 X-3 (0.1s
job-based disarm on M2) and G-10 (disarm counts down in Hold) pass.
Adds live_fire_drills.py (arm-lifecycle sampler over TCP + HTTP).
