-
Tighten the two M3 x 8mm bolts. Do this in alternation in order to allow the hotend to rotate out of the way.
-
Finally, use two M3 x 8mm bolts to completely secure the DSH to the carraige.
-
-
-
Cable tie together the heater, thermistor and 30mm fan cables from each hotend.
-
Cable tie the right hotends cables to the backplate also.
