Wow. It's probably been almost 2 years since my old printer has done anything, but I think I'll have it working as soon as my Amazon order gets here today.
The other order will be tomorrow. A new Duet 2 Wifi with external antenna. I wasn't having reception problems before, so probably not necessary, but it''s what was in stock.
My spare board is gone. So is the Pi that I had programmed to manage many of the PanelDue functions, so I caved and bought the PanelDue controller and a 5" touchscreen. No idea how I'm going to mount it right now, but I'll think of something.
