Settings & data

The Settings screen holds the data folder, the machine configuration, the motor and load cell calibration, and the optional GitHub connection for bug reports.

The data folder

The app saves sample profiles, motion profiles, sets, and test results to a folder on your computer that you choose.

• The app asks for the folder when it first opens: click Choose data folder and pick (or create) one. The app remembers it across reloads.

  

• The current folder is shown as Current: …. Use Change data folder to switch.

• If the browser needs you to re-confirm access after a restart, the app asks again when it opens — click Allow access to “…”.

How data is organised

Inside the folder you'll find separate subfolders for sample profiles, motion profiles, sets, and test runs — each test run keeping its record alongside its CSV. There's also a small index file the app uses to find things quickly.

Rescan folder

The index is just a cache, and it can be rebuilt at any time. If runs don't show up after switching folders or editing files outside the app, click Rescan folder to regenerate it from what's actually on disk.

Test naming

New runs are numbered automatically: the next name is one more than the highest existing numeric name in the folder, so switching folders can't silently overwrite earlier results.

Why a browser can't 'open in Finder'

A web app can't open your OS file explorer or read arbitrary paths — it only has access to the folder you explicitly granted. That's a browser security boundary, not a missing feature.

The rest of the screen

With a machine connected, Settings continues with the machine configuration and the two calibration panels:

Keeping your data safe

When you choose a folder, the app also asks the browser not to clear its stored data. If anything goes wrong saving — access denied, disk full — you'll get a notification rather than a silent failure. Your results live in your own folder, so they're yours to back up and move like any other files.
