BIQU H2 Direct Extruder Upgrade Kit for Hurakan 3D Printer Equipped with BIQU H2 V2S Direct Dual-Gear Extruder, BIQU MicroProbe V2, BIQU 4020 Blower Fan, Hurakan Toolboard

I adapted this to fit on an Anycubic Kobra Go that's been heavily modded. My only complaints are - The blower fan sounded like it was going to rip itself apart and felt like it right out of the box. Luckily I had a spare on hand. - The bed sensor is in a total crap position, you can tell it was an afterthought, tack-on last minute job. - The PCB that comes on it is hard to find a cable for, or the pin out, or any reference at all for that matter. That's a bummer because BIQU is normally really good with this. It's why I have this, 2 of their accelerometers and two of the micro probes, and the SKR 3, and well ... Let's just say pretty much anything I buy aftermarket comes from BTT, and for good reason! last but not least, it PRINTS F N AMAZING! Modded Kobra Printer with "David Orlo Centered-Z" Mod

First off the probe mounts on both were to high causing the nozzle to hit the bed first (no big deal I opened up the holes with my drill for adjustment) First failure was the microprobe wouldn't deploy unless manually deployed Second failure was a faulty thermistor that wouldn't read less than 200c

This head works beautifully on my biqu b1. I changed the carriage to the included hurrican part, but wired everything to my original USB-c expander. If a plug was included for the hurrican breakout board I would have done it differently. A fair bit of work to get it all done, but rewarded by much more reliable printing than the Bowden set up. I have never had a clog printing pce at 260 degrees with this setup. Couldn't be happier. Very easy to feed new filament. An order of magnitude improvement all around.
