    I turned the arbour to grind it and it pulls the shell mill down and centered as the collet tightens into the rotary table center and pulls in.

    First testing of my grinder on the mill
    I finished the g-code and reground the shell mill. everything went perfect and the shell mill and diamond wheel survived.
    it took twenty runnings of the program to get below the damage. that will teach me to read what i type before hitting enter. the angles where supposed to be 5 degrees and .5 degrees and i got pretty close.

    image.jpg Got my electronics, did not have any paperwork for wiring. I looked at your pics and can't figure it out. I want to see if all works well before I leave feedback to vendor just in case something is broke. Is there a place online that has wiring info on this

    I think i am getting close with the two smaller motors but my wire colors are red, yellow, blue and green. I am assuming yellow will be black? I may have to hold off on the 4200 stepper because i am missing the terminal to hook it up. The pic is what is missing.

    the wire colors and locations are normally in the description in the ebay add. try looking there
    if not google the part number on the motor and go to pics you should find it

    Steve,
    I setup mach three same as the X2 and no joy, I think because my system is same as yours on the 45 you built, i will play with it more to see what i can get going.

    This website has a few videos setting up the electronics as well. He is using the C10 board. Well worth the watch as I followed along with him and learned alot.

    He goes into checking things with a meter so you don't let the smoke out.

    did you reboot the pc after installing mach3 everyone including me forgets to reboot.

    x step pin 2
    x dir pin 3
    y step pin 4
    y dir pin 5
    z step pin 6
    z dir pin 7
    all enables to pin 17
    for the black controllers, all commons ( connectors that say + ) are 5v positive just jumper across, three small jumpers on the controller then one wire back to common terminal or 5v positive if thats what your breakout board has.
    you should start a thread and post better pics of the controller terminals so i know what i'm helping you wire. the big controller is different but most of the extra wire terminals you wont be using on it. but the pic is fuzzy

    kewl
    listen if you post in your build thread i will see it i get emails for every thread i reply in. that way everything pretaining to each persons build stays all in one place and makes it easier for others to follow.
    play with the dxf part of d2nc that is what you want to learn first.

    my cnc capability is limited to a zen toolworks cnc so i have to do all the work manually. I tried opening your dxf files im emachine and draftsite but cant get dxf to 0 so i can figure out demensions so i will print out each drawing and see if i can figure out coordinates.

    select a part of the drawing in emachineshop and look up at the top it will show the size of what you selected.
    or select the entire drawing and on the upper left type in the cordinates as 0, 0

    my drawings are not a set of plans and should be checked to what you are building. most drawings were done on the fly as needed and there may be modified drawings of the same part. sorry they were not planned out better but i never concidered someone making a copy of my mill.
    I hope they are helpful

    this is a video of the z axis after calibrating and setting backlash compensation. the movements are in .0001 increments reversing the direction.
    this impressed me concidering this head weighs 300lb and i bought the cheapest parts i could afford for this build.

    Very inspirational thread. I am planning a conversion of my RF31, and have been slowly gathering parts. I have my electronics mostly sourced and partially operational. My biggest challenge is taking apart my mill to spec ballscrews and generally survey the heck out of it, then reassembling it to build its own parts.
    Thank you for sharing your conversion.
