Hi!
Is it possible to adjust labware liquid seeking height in a method so that the seek height is variable across different instances of the same labware on the deck? I thought of trying to use the labware property query library, but I don’t know what string to input as i_strPropertyKey.

Hi @TechsupportCLS ,
That particular function only adjusts the labware properties for the labware on the deck layout:
You technically could adjust the labware definition value for seek height at run time, but you won’t see any change until the next run as the labware does not actively change. And even then, this change would apply to all instances to that labware which is probably not what you are looking for.
I think what you are looking for is to start the search lower as your volumes go down. If that is the case, then I believe this setting would handle that in the system config editor.
It requires sample tracking to be turned on, and I believe it alters the search start height after a volume has been set for a container. This may require you to detect the liquid level height, convert to volume and then set the container volume using LabwareState:SetLabwareVolume.
This would only need to be done once though. Sample tracking will start removing volume as you aspirate from the source.

Thank you for replying so quickly!
I’m actually trying to adjust the seek heigh for different buffers on the deck, some are around 30mm and others at 8mm. Would setting the expected volume functionally do the same thing?
Hi @TechsupportCLS ,
I would expect this feature was made for this type of situation. Just be aware that if you set the volume height lower than what is actually in the reservoir, then you may start seeing unexpected cLLD errors as the search height would start below the reagent.
