Opentrons App

• Separated the "Pipettes and Modules" page into two separate pages
• Added in a missing prompt to use a calibration block during certain tip-length calibrations
• Removed auto-resume behavior when clicking "Back" from the protocol run cancellation confirmation alert

• Added a fix for incorrect pipette offset data causing differences in pipettes' Z-positioning
• Fixed pipettes not lowering enough during the "Change Pipette" flow
• Fixed a variety of bugs in how pipette settings are saved that could cause invalid configuration data

3.20.0

Robot Software and Opentrons App 3.20.0

v2.4.2

Patches two bugs in App:

1. Flask server correctly parses WellSeries containing WellSeries, so as not to duplicate containers in calibration
2. App-shell calls BrowserWindow.loadURL() within a setTimeout() to hopefully avoid trouble with Chromium not actually sending that request to Flask

v2.4.1

New Feature

Run with USB cable disconnected (requires latest v2.0.0 Smoothie firmware). If the "Run Job" button is pressed in the UI with a SHIFT-CLICK, the protocol will be converted to a .gcode file, then uploaded to the Smoothieboard to be run independent of any connected computer.

Bug Fix

To avoid any garbage data received during fast movements, driver.wait_for_arrival() will swallow any bad data.

Also adds more logging to app-shell to help determine why Windows users experience a white screen on app open.

2.4.0

• Support via Intercom
• User identitiy
• Motor driver to use latest Smoothie firmware
• In-app analytics

2.2.0

New Features

• Enhanced error handling while running protocol
• Dropping support for Python 3.4, requiring Python 3.5 only
• Adds new feature to touch_tip() allowing optional numeric height offset. Example: pipette.touch_tip(-2)
• Adds new API feature pipette.air_gap(volume)
• Adds new container definitions

Bugs Fixed

• Removes bug on Windows when deleting old calibration files
• Fixes tip positions of "tiprack-200ul" and "tiprack-10ul"
• Removes bug in containers with wells of different radiuses
