Venus 6.2 : 2D autoload and NGS method

Hamilton (Venus)

Good morning everybody,

I am currently implementing one of my newest methods on a new generation NGSStar but I am running into an issue with 1 carrier and 1 carrier only…

It’s the infamous PLT_Stacker_L4ST (In other words, the spikey thing)

Basically below snippet of the tracefile shows what I am seeing.

The issue here is that I already defined in my Labware property for the carrier that it should not read the barcode MlStarNoReadBarcode from 0 → 1

Every other carrier works and doesn’t show any issue with the 2D autoload we have, it’s only this carrier.

I bet it’s something simple :smiley:

Hi @Pascal ,

Can you try changing the property MlStarCarCountOfBCPos from 4 to 0?

Yep, told you it was simple.

Did i miss this in the manual?

Hi @Pascal ,

I don’t believe so. I think this error is specific to this stacker carrier and how the WOI for the 2D autoload is set. Since you aren’t scanning barcodes, changing the number of positions to 0 in the properties skips the logic for setting the WOI altogether which prevents the error you are seeing.

Setting MlStarNoReadBarcode to 0 accomplishes the same thing, but the WOI still gets set in the background which leads to the error as there is a range issue for this particular carrier.

Using MlStarNoReadBarcode on a standard carrier should still work as expected.

We are working to prevent this error from happening in future releases, but this workaround has been getting past the issue.
