Got a 16ch hikvision nvr linked around the house and garage already with only 6ch being used so far.
Putting a 5mp camera into the camera enclosure also means that it's accessible through my security app/live view.
As for running the printer it's still manual controls.
But am looking at either upgrading the hotend and other bits or just replacing the whole printer.
