Trying to get my RLV11 working

Thanks John, I think the insanity is my own! After changing those
switches I accidentally put the M8014 above the M8013. I've swapped
them and now get slightly different results:

One note, it now takes a while for it to start printing anything,
which I think might mean it's running some of the first test
successfully before getting to these. Earlier runs would start
printing errors immediately.
