bug: robot frozen when a protocol is cancelled #14033

Open MurielGelin opened 9 months ago

MurielGelin commented 9 months ago

Overview

when you cancel a protocol, it fails to cancel, then the only solution is to restart the frozen robot, and so the previously determined offset data are not saved !

Steps to reproduce

No response

Current behavior

No response

Expected behavior

when a protocol is cancelled, the offset data should not be lost, the robot should not freeze indefinitely

Operating system

Linux

System and robot setup or anything else?

v7.02

I have the same problem with a Windows PC. My student with a Mac laptop can cancel programs without any issue.

danolson1 commented 7 months ago

I have the same problem.

There was a note that this was fixed in version 7.1.0 https://github.com/Opentrons/opentrons/pull/14215. I am running version 7.1.1, and still seem to be having this problem.

@sfoster1 Seth, do you have any ideas what might be going on?

I have experienced this issue/bug over my last runs. The app is trying to cancel the run, but is stopped. I reset it by turning off and on the OT-2 Not all runs which are cancelled, but 50% so far. It seems like my issue happens when the gantry is suppose to be active: pipetting or moving, but I have not seen this enough to be 100% sure yet.

Thanks for your reports.

We fixed some more cases of this in v7.2.0 (PR #14312). Does it seem like these line up with your observations?

cancel while dropping tip
cancel while homing pipette plungers

If you still notice this problem after updating to v7.2.0 (which isn't out yet, at the time of writing), please provide:

Protocol details
- Protocol Designer or Python
- The Python apiLevel, if you're using Python
- If you're able to share it, the protocol file itself and any custom labware definitions that are required to run it
A description of where your protocol was cancelled
- Videos or pictures are best, if you manage to catch it

Thank you!

Hi!

Opentrons OT-2 frozen after attempt to cancel protocol during "Blowing out at well A1 of Fixed Trash in at 92.86 µL/sec" step (run preview line 213, in "ADDING STANDARDS TO PCR tubes" part).

App Software: 7.3.1 Robot: v7.3.1 Firmware Version v1.1.0-25e5cea Supported Protocol API Versions v2.0 - v2.19

Running python protocol written by Opentrons support (apiLevel 2.13), adjusted myself and works fine (except for freezing when cancelling)

Protocol (in txt, could not attach .py file): Standard_curve_preparation_03072024.txt Custom labware definition: evosep_96_pcrstrip_rack.json

Used for preparing STD curve in epps and distibuting to PCR strips. Left pipette: single p1000 Right pipette: single p300

Thanks a lot for your help!
