After seeing Stefan's video https://www.youtube.com/watch?v=_Soz8z-vAIw on how to use a Volcano to improve printing speed I thought I try this on my BiquH2 Extruder, To enable me to do this I designed and printed a new fan duct, bracket and BL touch spacer.
Watch the video and then if interested buy a Volcano nozzle and print the new fan duct, bracket and BLTouch spacer (if fitted).
The Volcano Nozzle is 8.5mm longer than the standard nozzle fitted in the BiquH2 so use two M6 copper nuts to help extend the heat sink. The nut(s) will need reducing in thickness to allow the nozzle to tighten onto the heat break. I also reduced the diameter of the nut adjacent to the heater block so it fitted through the silicone sock. I did this by mounting the nuts on a bolt and then used this in a drill to rotate against a file.
