DMT48270T043_07W – the LCD


DWIN.COM.CN Link to Screens

Hmm, Looking at DWIN.COM.CN…There’s quite a few LCD’s that may fit the bill- quickly copy / pasted the parts into Excel – All are 2Gig memory and 4.3″ screens


Looks like the screen variation I have is a DGUSII screen…….Based around the DMT48270T043_07W  , my touch sensor cable is slightly different, the PCB is slightly different – no battery, probably no RTC on-board. Given the ‘standard’ config and comms, I’d be quite confident now that I can

  • Buy a replacement screen
  • Tinker with my original screen firmware
  • replace all the bitmaps for Homer simspon, Crazy Frog – or whatever
  • Abuse the unused ‘speaker’ terminal somehow!

Further research seeing if there’s any SDK or software available for DGUS has shown that DGUS is some type of ‘standard’ and there are many third parties that are producing DGUS screens – most of which follow a similar format of part numbers

Even Further clicking (second page on google)

Github for ADVI3++ No idea what ADVI3++ is, however, it DOES reference DGUS SDK

Scroling down – WOOOOOO..looks like we have an SDK software download!!!.

Great, just how far down does this LCD rabbit hole go!


Looks like ADVi3++ ‘may’ be something to do with 3D printers………The Circle is thus complete…Looks like the DGUS system is used on some 3D printers somehow, that’s for another day I think.

Reading the Home Page

ADVi3++ is a custom firmware for Wanaho Duplicator i3+ printers (and their clones like the Monoprice Select Plus).”

Looks like someone else has done a chunk of the work for updating the LCD firmware already!…..Don’t you just love the open source community and a few hours of googling 🙂

Now I know what to look for, there’s a fair few DGUS type additions to Marlin, LOTS of ideas for a future ‘hack’

Tune in next week for the next exciting episode of That middle aged fart’s adventures in 3d Printing   tearing down a brand new 3D printer to see how easy I can break it!
