[feat] plugin SECOM user simulator: new simulation mode for intensive usage - #3566
Conversation
📝 WalkthroughWalkthroughThe simulator now selects METEOR or SECOM-specific names and text, with compatibility support for older Odemis versions. Shared helpers initialize simulations and locate fluorescence streams. Fluorescence focus simulation restores focus before completion. The new intensive-use simulation varies exposure and moves focus, filter wheel, and stigmator axes while honoring stop requests and restoring interface state. Sequence Diagram(s)sequenceDiagram

Merge Risk: 🟡 Moderate · up to The intensive-use simulator can leave microscope axes at unintended positions when stopped, and setup failures can leave its dialog actions disabled. These behaviors should be corrected before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Line 70: Update the “Intensive use” button registration in the dialog setup to
use the _sim_intensive_use callback instead of _sim_fluo_search, while leaving
the button label and styling unchanged.
- Line 220: Update the movement flow around f_stigmator and the forward-move
exit so each axis’s initial position is saved before movement and all
successfully started moves are restored in a cleanup path on every exit,
including Stop requests. Restore the saved stigmator position instead of
hard-coding rz to zero, and run this motion cleanup before the existing UI
cleanup.

🟡 Changes recommended
The new intensive simulation mode is not correctly wired from the dialog and the intensive routine can leave hardware state altered due to not restoring the stigmator to its initial position.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR extends the SECOM/METEOR user simulator plugin to support METEOR labeling/backward compatibility and introduces a new “intensive usage” simulation intended to stress concurrent focus, filter, and stigmator movements.
Changes:
- Add microscope-specific naming (SECOM vs METEOR) for menu entry and dialog text.
- Refactor simulation setup/stream selection into helpers and add a new intensive simulation routine.
- Add a
TabNamefallback to keep the plugin usable with older Odemis versions.

Put simulation setup inside the cleanup scope.
_init_sim disables both action buttons before it looks up the tab. If neither tab exists, it raises LookupError before the finally block runs. Intensive mode also calls _get_fm_stream before its try, so its explicit ValueError leaves the dialog disabled when no fluorescence stream exists.
Move all failure-prone setup into each try/finally. Initialize any variables used by intensive cleanup before the try.
