@mark tomlinson I am going to try to integrate version 0.3.0 of the Robo LCD plugin for Octoprint in the next release. I just have to remember what the heck the root password was for my Octoprint server. Allen McAfee has several Git repositories under his name (https://github.com/AllenMcAfee) and is the main contributior for several forks under the name Robo3D (https://github.com/Robo3D). The critical one for all existing Robo3D Beta/R1/R1+PLUS is the one for the LCD control (https://github.com/Robo3D/RoboLCD_Release). The filament sensor is generic and nothing special, it too is controlled by the rPi and not the Robo directly, just as I suspected all along.
