    Had to take a break from this for a few weeks due to the pressures of (paying) work, but now I'm back with a vengeance and looking to get it finished ASAP. First I've installed the steppers and wiring into the base:

    Just realised I need to get the oiling sorted before I go any further, so there's been some frantic buying of bits on the bay of fleas this afternoon: more pics coming it a few days when they land!

    So I've mostly gone with an idea Lee suggested, using 4mm pneumatic connectors/tube to supply lubrication to inaccessible parts:

    On the HGH15's I couldn't find any suitable adaptors so had to turn up some barbed brass push on thingies:

    Tried the same on the long axis, but then realised they would foul the ballscrew covers:

    Tried spinning the ballnuts through 180 degrees but then found everything was seizing up - turned out the ballnuts weren't concentric on the screws - thanks Fred - so those are going to have to be a manual lube.
    On the subject of lubrication, does anyone know where I can buy a sensible quantity of synthetic semi-fluid grease please? Looks like to be the DB's for this sort of setup.

    So onto the wiring... Found that the closed-loop steppers have the connectors on the encoder cables of such a length that they would sit in EXACTLY the wrong place - half way down the drag chain

    My mini-mill has no practical way to get oil to the ball-nuts or the bearings riding on the supported rails, instead I lift the rubber skirts every once in a while and squirt a load of a TF2 Teflon oil onto the shiny bits:

    No doubt this isn't the done thing, but having done it for five or so years, I'll probably keep doing it. There's logic for ya.

    Nice build BTW.
