The dosing automation works in the leader but not in the workers

Hi everyone, I want to start a fed-batch dosing automation, but it only works in the leader and not in the workers. The motor doesn’t respond when the automation starts—I can see the dosing volume change in the logs, but nothing is happening. The pumps are working fine, as I have just calibrated them, and they are also responsive under the dosing tab, where I can run them continuously. Has anyone encountered this problem? Thanks in advance.

Hi @OskarOlofsson

  • Do other jobs work (stirring, etc) on the workers - is it just the dosing automation that’s not working?

  • Is this a custom automation or the built-in fed-batch automation?

  • And the logs you are seeing: those are from the workers? That is, you see logs like “Adding 0.5 mL media.” from the worker Pioreactors?

  • Did your pump calibrations go as expected? Can you show me a few of the media calibration charts / data?

Hi @CamDavidsonPilon
Thanks for your answer! It made me check the calibration curves, and they were way off. I recalibrated them, and now it works.
