Thank you so much for the thorough response!
It seems it’s easier to deal with the firmware from a Windows machine, so I’ll deal with that back in the office next week.
If that doesn’t help I’ll take it out of the case again and see what’s up. I don’t have a soldering iron yet, but if it’s an obvious problem this might be what pushes me over the edge. :)
Lego is doing a great job here exploring alternative materials and encouraging research and production.
It’s absurd that they seem to be doing it all by themselves. Plastic is everywhere, everybody claims to care, but Lego seems to be the only ones to put their money where their mouth is.
Probably helps that they’ve realised they can pretty much charge any price for their pieces of plastic. So they have money to spend. But still.
