Slide the Hotend onto the carriage like shown and tighten the M4 bolts down onto it, clamping it in place.

As you tighten, the hotend may move, push the hotend into its slot to prevent as much of this as possible.

Make sure that the hotend is orientated like shown, with the cables coming out in the direction of the 40mm fan.

Fix the levelling probe onto the back of the tool carriage to complete the print head.

The bottom of the probe should be approx 1mm above the bottom of the hotend's nozzle.

Cut 85CM of the braided cable sleeving.

Melt the ends with a lighter to prevent fraying.

Slide the braided sleeving over the cables.

Create some relief/slack in the cables.

Tie the cables onto the carriage firmly with two cable ties.

Push the print head out to the end of the gantry.

Cable tie the cables to the gantry.
