Been trying to get an LDO 2004 smart controller to work with the Eisny Retro, I didn't think there was anything different on the board but I've tried 2 and neither work. I've define the correct display unless I'm missing something else. Marlin 1.1.9 bugfix. I can get the full graphic smart display to work just fine. I've used several generic smart controller displays off Amazon and never an issue. Anybody got any ideas??
