[MSD-302] Milling pattern spot size correction - #3563
Conversation
There was a problem hiding this comment.
🟡 Changes recommended
It introduces at least one confirmed functional bug (incorrect Microexpansion default name) plus gaps that can cause runtime failures (si_prefix validation) and missing test coverage for the new field on non-rectangle patterns.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR introduces a spot size correction parameter for milling patterns, threading it from pattern parameters → UI controls/overlay visualization → fibsemOS conversion, with supporting test updates.
Changes:
- Added
spot_size_correctionto milling pattern parameter models and default task YAML serialization/deserialization. - Updated GUI milling overlays to visualize corrected vs. estimated uncorrected openings, and added a UI field (µm) for the correction value.
- Applied the correction during fibsemOS pattern conversion (including trench spacing compensation to preserve displayed trench positions), with additional focused tests.

Merge Risk: 🟡 Moderate · up to The correction feature can misrepresent the estimated milled opening for rotated patterns, and malformed default trench correction values may prevent affected tasks from loading correctly.

In `@src/odemis/acq/milling/milling_tasks.yaml`:
- Line 43: Remove the U+200B zero-width characters preceding the
spot_size_correction values on both affected entries, and ensure each value is
entered as the plain numeric scalar 0.0 so TrenchPatternParameters.from_dict
loads it correctly.
In `@src/odemis/acq/milling/patterns.py`:
- Around line 59-71: Apply complete Python declarations across all affected
sites: in src/odemis/acq/milling/patterns.py lines 59-71, 111-121, and 194-204,
annotate every constructor parameter, add -> None, and provide constructor
docstrings; in src/odemis/acq/milling/test/fibsemos_test.py lines 59-69 and
71-79, annotate each helper’s parameter and return type and add docstrings; in
lines 141-149 and 152-180, add class and method docstrings with complete type
annotations. Preserve existing behavior and use appropriate existing types for
each declaration.
Apply the same fix in `@src/odemis/gui/comp/milling.py` around lines 74 - 83: Same
annotation and docstring remediation for the activation handlers.
In `@src/odemis/gui/comp/milling.py`:
- Around line 74-83: Update the milling validation and enablement flow
associated with spot_size_correction so the correction is strictly smaller than
every affected pattern dimension, not merely within its 0–900 µm attribute
range. Reuse the existing shape-point validation path and ensure the milling
action remains disabled whenever any corrected dimension would be non-positive.
In `@src/odemis/gui/cont/milling.py`:
- Around line 124-132: Update the correction-overlay geometry around the extrema
and estimated bounds so correction expands each rotated milling-pattern edge
along its local normal rather than enlarging an axis-aligned bounding box.
Preserve the pattern’s rotation in the dashed outline and shaded band, and add a
regression test covering a non-zero rotation.

desired_size − correction.Workflow:
The user first mills a calibration opening with the spot size correction set to zero. They then place the solid outline, which represents the desired opening, over the calibration opening and increase the spot size correction until the dashed outline matches the observed opening. The smaller dotted area shown in the figure represents the corrected scan area sent to fibsemOS and the microscope.
The dotted overlay is not shown to the user, keeping the interface less cluttered. It is included here only for illustration.
This calibration workflow is only necessary when the appropriate correction is unknown. If the correction value for the selected voltage/current combination is already known, the user can enter it directly without milling a calibration opening.
