v1.2.2

Daisy Controller 1.2.2 — universal macOS build (Apple Silicon + Intel) and a 64-bit Windows installer, seeded with Daisy Library 1.6.2. This release includes everything since 1.1.0.

Instruments

• Mass flow controller: Start now delivers the Target volume at the set flow rate, and the controller closes its own valve when the volume is reached, even if the computer disconnects. New Dispensed and Remaining readouts; volumes are in standard litres (SL).
• Mass flow controller: Ramp to target takes a ramp duration and the controller reaches the flow rate smoothly over that time. Stop and Pause always cut the gas at once.
• Mass flow controller: full scale is read from each channel when the module connects, and live readings show any warnings the controller reports.
• Daisy Process: a Probe calibration section on channels holding a pH probe, with one- and two-point calibration and a check of the current offset and slope.
• Peri S and Peri XL: the panels match their fixed pump heads. The roller and tubing pickers borrowed from the Peri T are gone; enter your measured flow at 60 rpm as the Calibration value.
• Peri XL runs up to 600 rpm, so large tubing can reach the full flow range on the product sheet.
• Pistons: aspirate speed is capped below dispense speed, as the pump maker recommends, and the panel shows each pump's aspirate limit.
• Pistons: the position marker follows the pump closely, and the volume readout shows the volume you asked for.
• Gantry: travel limits are read from the instrument, and number boxes accept only the stage's real resolution.
• Z Stage 85 mm is supported.
• New product photos for the Peri S, the Gantry and the mass flow controller.

Errors and safety

• When an instrument refuses a command or reports a fault, the message now says what to do, for example "The valve has lost track of its position. Home it before using it again." The technical detail is still available under Details in the message log.
• The homing prompt appears only when homing is the fix, and it reliably appears again after a rescan.
• If a Stop may not have completed, you are told to press Stop again.
• One unsupported instrument no longer hides every other instrument; it shows as Not supported and the rest work normally.
• Pausing a recipe holds a gantry or Z stage move and Resume finishes it; stopping a recipe keeps the stage's position and asks for a re-home before the next move.
• Panel Pause and Resume no longer wait behind a running stage move.
• A recipe runs on exactly the instrument it names when two of the same kind are connected.

Notebook

• Per-cell time estimates with a live countdown, and the running cell's status in the footer.
• Cells can draw live output: charts, tables and images that update while the cell runs.
• Estimate no longer runs a cell's ordinary code a second time, so file writes and other side effects happen once per Run.
• The AI assistant asks once for any values it needs, offering defaults, or writes the code straight away.

App

• Installing or switching the Daisy Library restarts the app onto the new version automatically, and waits while anything is running.
• A release can now require a minimum app version. An older version keeps working for viewing and editing, but stops connecting instruments until it is updated.
• Bundled Daisy Library 1.6.2: plain-language error messages, a fixed 8-roller head on the Peri S, and refusals from valve banks reported clearly instead of as a timeout.

Known issue

• Mass flow controller: pausing a dose and then resuming may not continue the dose on some controllers. Until this is fixed, use Stop and start a new dose for the remaining volume.
