After running a mix of PhiX and other libraries Q30 plots are still not great but perhaps less terrible. Attached here are two plots showing a PhiX lane as well as a Nextera lane (PhiX is missing one of the two index reads).

While neither are bottoming out as before there's certainly a steep downward trend in read after the intensity jump. This run did "meet spec" for a 3k run (75% >Q30) but Illumina still wants to send out an "instrument expert" to have a look at our machine.
