  2. Re: Looking for an isolation transformer for a Haas vf2 .

    I just remembered I might have another 208V VF-2 transformer at my shop in Merritt Island FL.
    PM me if you are interested.

    I have 2 systems and will likely buy another

    Dylwad,

    Is it really true? I use it almost every day. (big mill and PCB router)

    I'd love some support and I'd love to see Carkin do the next generation code and board.

    Best Regards,

    Clive,

    I used surplus old reel-to-reel computer tape drive motors (approx 1/2 HP) and affixed gecko's to the encoder end in a short extensoin tube. There is a heatsing at the distal end of the...

    to paraphrase Peter Sellers:

    Wow,

    The part in the photo is die cast.
    You can tell by the parting line on the part where the two mold halves seperate.

    There is no second driling operation, the holes are molded-in.

    Nicole,

    They are fantastic machines and are well suited for re-conversion to PC based CNC. I love mine. The website is a couple of years behind, but you can see the move, cleaning, retrofit and...

    g code generation

    What form is the data in?
    It should be "relatively" easy to get it into a format where a small program could generate the g code.

    Or am I missing something?

    J,

    I did not replace them, only cleaned them and changed the wiring. My setup is likely different since you had a different controller.

    The moving parts (XY) have taper blocks that intersect...

    CAD Help

    Mike,

    I don't know about your converter, but your dxf likely needs to be closed so the converter can make the pocket.

    In your DXF the top line is not touching either arc.

    You will also...

    Don't freak out

    From what Al says and what I've seen so far it looks like you have everything you need excepe (digital) encoders.

    You will need to do a tiny motor mod (if your motors are good) to remove the...

    Yup

    That small motor looking deal looks very much like a "syncro resolver" to me. 2 wires are an input "AC excitation" and the three other wires are the sine / cosine outputs.

    I did not see a...

    2 wires on the same pin. Nope, does not make sense unless its a transformer coupled resolver (unlikely)

    Have you taken it apart?

    J,

    I'd pull it apart, trace out, and subtract the obvious:

    Likely that it does not have a brake.

    so you should be left with :

    Motor Wires (2) fat red and black
    Tach wires (if it has a...

    Find the red and black wires from the encoder.

    The encoders you have might not work

    J,

    You might have resolvers, not "encoders" Resolvers output an analog signal that varies with the proximity to the lines of the encoder wheel. While possibly more accurate (due to the ability...

    Thanks for the pointers. How much depth of cut? I normally cheat on this since I have a knee. I'll start at something that I think will work (like 0.020) and crank on the knee to find a...

    Holey Moley! FANTASTIC!

    I assume that you have another CNC machine that you made these parts on.

    Did you solid model them? If yes, what software? If no, how did you rough in the design?
