This video shows a short test of the ANet ET4+ 3D Printer. It provides some cool features that allow continuing after power off and changing the filament mid-print. I tested the filament change to print a functional lamp case for a simple 16x16 pixel RGB LED matrix. The lamp is driven by the ESP8266 and WLED. It can be controlled over WiFi and used for several IoT purposes.
