    All the CNC parts for G0704

    Would someone be kind to list all the pieces and kits I need to convert the G0704 to CNC? I have a good computer.
    Seen these so far, anything else?

    I would recommend the dmm servo kit as they are a local company. I can make the motor mount plates for you if you are interested.

    I'm new here so I don't much know anything of these forums, but I shall. I've only used a small manual mill and know just enough to be dangerous. I bought this after reading how successful the mill has been for people.
    I don't want to mess around with partial kits and such, the more complete I can buy the components is best.

    Looking at the parts PDF (#246-2 retainer cup) has a nasty wobble. I'm thinking this is not a good thing as it sits on the top of the drawbar. I've not even cut anything yet.

    I saw that also when I first started mine and thought there was something wrong. Don't worry bout it though it isn't because your spindle is messed up

    Those have very fine threads, it's possible they crossthreaded it during assembly.
    Unscrew it, and check it out, one was sent recently with the threads miscut.
    I tossed mine early on and went with a standard bolt and made a spanner.

    Must be a QA or person with no sleep on the assembly line. I have the wobble as well.

    Sorry about the rotation of the video, I was on my phone and it auto rotates for me.

    Here's a video of mine.

    The cap mentioned previously does unscrew. (Just use the larger wrench included and also that new spindle pin to hold the spindle if you want).

    Question, which part is cross threaded the retainer cup's threading or the spindle part #246V2

    Wobble is nothing unusual from machines like this that have long narrow unsupported upper spindles, many machines will experience some wobble.
    The spindle nose is where it counts.
    You no doubt could move the top back and forth with your fingers.
    If it vibrates too much at speed, remove the retainer, inspect and carefully reinstall so not to crossthread.
    I'd just toss it like many of us have especially since you have the spindle wrench now.
