You can loose a finger that’s fine, just don’t damage your extruder.ĭont forget to check between the teeth of the gears ensuring they are debris and burr free. Just be careful not to damage the teeth of the gear. If this does happen, it’s easily removed with a craft knife. Nonetheless it is worth keeping an eye on. While I have been reassured by BIQU that they are tightening up their procedures. As a result some of the glue had run down into the teeth of the gear. So BIQU glued the grub screws into place on the filament gear. However BIQU are so certain of the longevity of the gears, they feel they need never removing. While the filament gear is attached to the larger output gear that has just been removed. Revealing the smaller integrated heatsink for the heat break. With the parts separated remove the largest gear (Output gear) by gently wiggling it out. Importantly the long filament arm needs to be pushed back slightly to release the two parts freely. Importantly it is always prudent to check that the gears and filament paths are clean and unhindered.įirstly start by removing the heatsink from the BIQU H2 extruder by unscrewing the M3x35mm cup head screws.Īllowing the heatsink to be removed and the BIQU H2 extruder to disassemble in two parts. Without a doubt one of the first things a receiver of a new filament extruder should do is to disassemble it. Also there is the Allen keys and Bigtree-Tech yellow duck. Moreover this fan is super quiet and would give Noctua fans a run for their money. But one of the biggest surprises is the 35mmx10mm 24V heatsink fan. Similarly, so too is the 40W heating element and 100K cartridge thermistor. However the 0.4mm brass nozzle is fairly standard. Especially with its chamfered and beveled edges. Furthermore the heater block hidden by its silicone sock, is again very unique.

While also considering the practicalities of upgrading to the BIQU H2 Extruder, all of which are summarised within this review. But also on testing the extruders performance and reliability. However since then work has continued in not only designing a mount. Some time ago, we released the first looks into the BIQU H2 extruder.
