As requested, I'm starting a new thread. Not sure if this is the correct section. If not, feel free to move it.
@deckingman was specifically asked by the Duet engineers to post here
For anyone watching this thread, and for those who have contributed, I just want to say that the Duet team and I have opened up the communication medium that we used at the very start (when Gen 3 was still at the pre-production stage), in order to work together to resolve these issues. That's nothing personal - just that these forums are maybe not the best way to post messages rapidly back and forth between us.
They have now opened up more direct channels.
Just talk to the Duet engineers directly and spare everyone else from your dog and pony show.
No-one is forcing you to click on this thread, so consider yourself spared.
