Dedicated built-in Y-type splitter for H2 series

All hardware and screws need to be obtained by disassembling the Bambu black 5-way splitter (as shown in the figure)

The rear TPU anti-wear pad needs to be reinforced and adhered with 3M double-sided tape

⚠️The internal splitter needs to be used with a low friction inlet (in fact, all internal splitters need to do this)

Function: Reduce excessive drag resistance from original rubber parts to prevent damage to the pneumatic coupler at the tool head ↓Download here

1.PTFE cable use inner diameter 2.5mm outer diameter 4mm (consistent with official specifications) / The PTFE cable end should be cut straight and pushed in with a little force until it can no longer be advanced otherwise, feeding failures and jams will occur

2.This model is highly dependent on flow rate calibration accuracy which directly determines whether the buckle, with protrusions of only a few microns, can securely fasten the pneumatic coupler

If you find that the pneumatic coupler detaches with a pull, please recalibrate or reduce the calibration value to make the corners sharper

Personally, with ABS-CF, K 0.020 can fully secure it. If it still cannot be secured, you can reduce it to K 0.018 or even lower

3.Recommended materials: ABS-CF > ABS > PETG-CF for printing PLA is prohibited For long-term high-temperature printing, only ABS-CF>ABS is recommended

⚠️(If you have M3X6 screws, please choose another more reliable print profile)

4.Install in the middle of two cable clips. Avoid installing it on the side near the buffer's wireless clip, as this will affect the buffer's operation (no splitter should be installed at the very back)

_🎈Weighing only 6.6 grams to avoid additional inertia affecting print quality
_ 🔧No fixation required. Small forward and backward movements during large range movements provide tension release. Friction is alleviated by the low-resistance TPU printed part on the back
_ 💢Dedicated TPU feed channel below the splitter (compatible with external or assist modules), not suitable for hard materials
_ ✔The main feed channel above has no resistance and is compatible with all filaments
_ ✨Now printing TPU no longer requires plugging and unplugging the rear feed tube

Regarding the reasons for the curved and straight tube distribution:

___ The top straight-through tube is used to completely solve the problem of additional resistance caused by traditional bent-tube three-way guides, which requires frequent filament loading and unloading for Vortek multi-color printing

(This also helps to avoid the problem of excessive buffer resistance triggered when the Bambu automatic splitter module is installed on the basis of a traditional curved Y-splitter)

___ The bottom feed port has very low resistance for soft TPU filament (allowing more bending), and can achieve completely unobstructed feeding with the TPU assist module
