    Yes and yes, but slack for movement doesn't present much of a challenge as the only pipes that move are the two connected to the gantry, which can be routed with the Y and Z axis motors. The challenge is when you have rotating nuts...

    If you put plenty of oil in then yes, it goes everywhere. Perhaps it could be managed with more careful control of the quantity.

    Looks okay, uses oil, but I don't understand why these and other accessories, Hiwin especially, are so difficult to source and purchase. it's always like finding rocking horse cac.

    In the same document is Hiwin - Intelligent Linear Guideway, looks like it might have potential to be used for position feedback similar to an encoder.

    If you over fill with grease it comes out and the same is true with oil. The trick is to regulate the flow or pulse small quirts at regular intervals so just enough to coat the bearings with fine smear on rails. It's not difficult really.
    My mill as got programmable lube system which can pulse the pump and it just oils the bearings and ways nicely with very little to no excess, certainly not enough to contaminate anything.
    You can buy these cheap enough now and they even do ones which will pump grease.

    Same thing could easily be made with an arduino cycling a pump.

    You can do a central lube system and still use grease. Our Morbidelli has one.
