@bennthomsen It looks like both this and #7838 now holds improvements for both instruments. Should we merge one of them and close the other?

Arrr what an idiot I am. I have a combined branch that I merge both of these into for joint testing. But must have been on the wrong branch when merging at some stage.

Will abandon this one

@benn-thomsen No worries as long as there is a changelog entry for both drivers all is good.
