Indeed beneath timelapse everything else is working 
WebCam-Integration and also (in my case) direct Upload of GCodes from Simplify3D.
I've used Octoprint and Repetier-Server before too, but with my DuetWifi/DuetX5 and also my Radds (with an additional ESP286) i'm using nothing else as the WebInterface.
For the WebCam i'm using a Raspberry Pi 3 with MotionEyeOS, where i always save the Video-Stream and inside the WebIf i'm using the live-video Feed.
