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

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.

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
