Half way there! Go grab a drink.

\n

Next, we flip the assembly over and move the PTFE tubing out of the way because it's time to install the rear motor (Filaments Hub, Bambu Lab's naming).

\n
\n
\n

Here you use the 2.0 mm hex tool to install the four screws in each corner of the motor assembly (Filaments Hub). Press the flat PTFE release button (very bottom of this picture) and ensure it engages / disengages.

\n

For the bottom two screws (closest to the rear of the AMS), make sure you don't tighten them too much else they will peek out and can obstruct the rear rollers. The screws are tightened on a silicone pillar and does not require full tension.

\n
\n
\n

Next, connect the PTFE tubes from the front feeders to the motor assembly. The outer feeder PTFE tubes are routed through the Hydra printed parts, there is a cutout, it should become clear once your install them. 

\n

Make sure the PTFE locks properly so pull a little on each one once installed.

\n
\n
\n

Almost done. Now we install the AMS main board. There are two tabs on each side it goes under and it is fastened with two small screws in the middle (use 1.5 mm hex tool)

\n

Be careful with the capacitors on the board, they are located on the other side of the board in the pic below, these are guided through the holes in the printed part (see the picture just above).

\n
\n
\n

Connect all the cables to the main board. Check the third picture if you forgot where everything was connected. The ferrite core with the cables between the main board and the small rear PCB sits in the middle slot, it's just friction fit (not pictured here) so slide it in.

Time to install Hydra in the Bambu Lab AMS enclosure. Lean it towards you then fold it backwards.

\n
\n
\n

With the assembly still angled towards you, install the two cables, you can then fold down the assembly into the box.

\n
\n
\n

Fasten it with the two main frame screws. 2.0 mm hex tool is used.

\n

Notice! If the screw doesn't reach it's possible you downloaded an early update of version 1.03, unfortunately there was an error but it has been corrected. If so, use a longer screw or just drill the part a it a little deeper. Sorry!

\n
\n
\n

If you want to use the optional but recommended PTFE button feeders to both save the funnels and improve ergonomics, press the bottom of the feeder and at the same time install the button. Once done, press down the PTFE tube a little. 

\n

You must install the buttons after the main Hydra AMS is in place in the box, not before (there is not enough space otherwise).

\n
\n
\n

Connect the PTFE tube at the rear as well as the connector. Load up your spools.

\n

All done!

\n

Left: Hydra AMS without spool guides (see remix).

Right: Normal Hydra AMS.

Prelude, Precaution and some more tips

\n

Make sure the front feeders are fully inserted and tightened. Also make sure the bearings on the rollers are fully inserted over the shaft. Finally, 75.0 mm wide spools is the absolute max, else the spools will not turn like they are supposed to. If you use cardboard spools, add some electrical tape to the lip to get better grip.

\n

If you use the the middle position of the rear rollers and your printed Hydra parts were ever so slightly warped at the side walls and/or dividers, for example if they were printed in ABS with too much cooling, they could prevent the rollers from rolling perfectly smooth and instead with some restriction. We don't want that.

\n

If so don't worry, just print the optional roller support bars to ensure perfect alignment of the roller slots and the rollers will spin perfectly again.

\n

These are not required for the rear and second to rear positions of the rollers (normal position for large spools).

\n

To use, just press in the roller support in the slot behind the roller. It should also fit in the slot in front of the roller unless the spool is too small. If so, move the roller to the front most position instead and place the support bar behind. Install it upside down compared to how it was printed so with the rounded side down in the roller slot.

\n

Another good idea is to use my Adjustable Spool Holder for Silica Gel / Spool Weight that's compatible with both Hydra AMS and Bambu Lab AMS. 

\n

This keeps the spools dry and adds some weight to them, preventing near empty spools to jump up and jam. It can still happen but is less likely.

\n

That's it! Thanks for your support.
