Anything else?

I've been having frustrations with Bambu Studio as it asks me for the IP address and Access Code for the H2D every single time I use it. I decided to try OrcaSlicer as an alternative as I saw that there was a recently completed merge request with H2D support (ref #9254 and #10780). It wasn't included in the released version so I downloaded the nightly.

I've tried a couple of different models but, while it connects to the printer and synchronises information, it is unable to actually print anything, always producing the error message shown above.
