Step 1 — Metal Ubis Hot End without the Fan Power PCB

Thank you for purchasing the new Metal Ubis Hot End. This guide will show you how to
properly connect the Metal Ubis to your Printrboard.
 DO NOT disconnect or connect wires into your Printrboard while it is powered on. Unplug
the power before following this guide.

First take out all the content of your Metal Ubis Hot End.

You will notice a piece of paper inside with IMPORTANT instructions of using your metal
hot end.

#1 - Always have fan on and running before you heat up hot end.

#2 - Change your retraction settings in whichever slicing software you use to 0.3mm0.5mm.

If you do not follow these two instructions, you will clog and damage your new Metal Ubis
Hot End.
