A 1300C 3D printer hotend for printing metals on the Creality Ender3 [video] (youtube.com)

Dang, and I’m out here still trying to figure out how to level the ender3 v2 bed. In the process of updating the firmware, the screen display became corrupted. And crealty has not got back to me on my tech ticket

This video shows the creation of a home made prototype, without showing it in operation.

It's a complete unknown whether it actually works. :(
