BIQU H2 Fan Duct for CR-10S PRO V2 Stock Fan

thingiverse

This is a fan duct mount for the CR-10S Pro V2 to use with the BIQU H2 extruder. I used the mount from here: https://www.thingiverse.com/thing:4799902 TLDR; I edited the Tiny Machines firmware to make the BIQU H2 work with CR-10S Pro V2. Follow their instructions for updating the firmware and the only thing you have to do after that is a PID tune which is in the printer's menu with their firmware and change the retraction distance in your slicer to .5. https://drive.google.com/drive/folders/14qn087CFqZ7vsbjiVPKXF-NDH6x7Q41z?usp=sharing The BIQUH2 doesn't just work with the stock firmware and there isn't anything out there yet that I could find so when I went to run the BL touch leveling, the BL touch was now off of the bed so the nozzle crashed into it...ouch. I haven't been 3d printing long and never even updated my machine's firmware but after trying everything else, editing the firmware was the only way. If I would've known this, I would've taken into account the position of everything before I switched all of the hardware but it was too late so I did my best. I lost 15mm on the Y axis but it was better that then the wheels grinding to get back there. I'm sure someone will come along and make a fine tuned firmware for this but right now it's actually working awesome for me. I printed a benchy at 150mm/s infill speed and 100mm/s wall speed, top/bottom speed and it looks just as good as the one I printed at 60 infill 30 wall. Back to the fan duct, the original mount used the fan duct from here https://www.thingiverse.com/thing:4789656 but after I printed it I realized it's not for the 10S pro and a totally different fan so I threw it in Tinkercad, smashed it together, stretched things out, added pieces in and basically Frankensteined it with https://www.thingiverse.com/thing:4546325/files I'm sure somebody can come up with something better but it works. I secured it with some some M3 screws and nuts including the ones from the stock fan duct. This was an experience but I'm really happy with how it prints now.
