Has anyone tried this Duck Pro custom firmware? I would but I'm only getting mine if it manages to connect to Octoprint.
Reading that repo seems to indicate it's still a custom klipper build, so there's no telling if you could still install OctoPrint on it or not. These in-built locked down klipper machines are usually hardware resource constrained too, so unless someone has posted processor/ memory specs it's hard to say if OctoPrint will even run on it.
I have a Kobra Max 3 and connected it to Octoprint with a Raspi 4 and a USB A to USB A cable. When I click on logs I'm able to see it sending Ok messages to itself, however so far no luck getting it to make any adjustments to my printer.
I have remote printing working, but it isn't reliable. It only sees 1 ACE, and then not every time. I was hoping to get Octoprint to connect and work. Guess for now I'll be walking over to the printer with a USB stick until someone smarter than me figures this out.
If you need someone to help test things I'm your guy.
