    Default Retrofit for CNC5

    Hi All...

    I just discovered the CNCzone and it is great... I have a CNC5 that has had the electronics poop out... Or at least I think so. The tape drive had a problem, so at the suggestion of a gentlemen on the Yahoo users group, I just un plugged the drive and entered a short program by hand. It worked as fine... After not using the lathe for a number of months, I tried it again and now it won't work at all... The little 1 amp fuse on the power supply pops as soon as I turn on the power... Oh well, time for a retrofit I suppose...

    Do any of you gentlemen have any suggestions for an idiot proof, bolt on, 'plug-n-play' retrofit system? Or how about a website that may offer such a system?

    I would like to get the lathe working again...

    Regards
    and Happy New Year to you all...

    Bob,

    I am retrofitting a Compact 5 PC lathe and have an available stepper board and original stepper mottors if you are interested. The Compact 5 PC and Compact 5 CNC use many of the same boards.

    The part number on the stepper motor board I have is:

    A6C403000
    A6PC-001/U4

    Look up the part number on your board and if the same this one may be of use to you.

    If interested we can discuss how to trade. I would consider selling or trading for tooling.

    Ed

    Thanks for the offer but I think I want to do a complete electronic retrofit of my lathe. I had already purchased a new tape drive to try to get my lathe back into operation and this swap was not sucessful... So I think a complete changeover is my best route...

    I tried the emulate this but i can only download a program from my CNC5 for some reason I cannot get the upload to work. I really do not understand this part:

    first lines and last lines = 100(0)
    add to end of line = "select CR+LF"

    Did you actually type in "select CR+LF" with quotes and all? I tried that plus just using ascii keys and still did not work.

    Any insight would be helpful.

    --------------------------------------------
    as for connecting to the compact 5 that
    appears to be where you are getting a little hung up. I have not
    been able to connect with anything but freenclink and here are the
    directions, this should work for any nc linking software, and if you
    cant find nclinkfree let me know i'll get it out there somewhere, it
    should be available from onecnc, but i can never find it on thier
    site.

    inside the nc software set it up in this manner
    set your com port to whatever one you want to use
    baud = 300
    data bits 7
    parity = even
    stop bits = 1
    xon/xoff not checked
    dtr/dsr not checked
    rts/cts not checked

    first lines and last lines = 100(0)
    i dont know why it's that way but it needs it there
    timing line delay (msec) = 0
    ignore line prefix = (
    add to end of line = "select CR+LF"

    ok, now that the options are set how to get the file over there

    turn on emco cnc
    start nclink free on the computer
    on the emco press the "H/C" button
    then hit the "inp" button
    then type '66'
    then "inp" again
    a screen should come up rs232 operation etc....
    then hit "inp" again
    the screen should say load program
    now go back to the computer and load up your program
    you want to send over in nc link
    go to utilities, then send
    do not mess with the settings and click on the start button
    the emco screen will say "program being loaded" and once done it will
    have the program up on the screen
    now go over to the emco and hit the start button
    -----------------------


    good luck and if you have any questions let me know and i'll try and help.

    Still have any parts available? I'm looking for a CPU board part number A6C114004 to upgrade my A6C114003.

    HI

    HAs anyone managed to get an emco compact 5 cnc to work from a dxf file yet?

    I am considering buying one but if I can find an easy way to run one from a dxf file I will stay away...

    Please let me know if anyone can help.

    Many Thanks

    Joel

    It is possible and actually quite easy to create a part and toolpaths using the obsolete Emco CAD/CAM DOS software, available from the Yahoo group "Emco_cnc_users", but you probably can't use AutoCAD or IntelliCAD (a free AutoCAD clone) for creating the DXF file – as the EMCO software won't read it correctly. You'll need to find some other CAD package and see if it works for creating compatible DXF files. I spent several hours yesterday to find which IntelliCAD 2000 DXF formats work and which do not. For some odd reason the imported DXF geometry was always shifted several inches from the (0,0) point and usually the DXF file couldn't be read in at all.

    The best way for you to go would be to retrofit the Compact 5 CNC lathe to use a normal PC computer and Mach3 as the controller. It's quite easy. After that you won't have any compatibility problems as most CAM software can export compatible G code for any lathe having Mach3 as the controller, and there won't be practically any file size limitations like the original CNC controller has.

    You'll probably need to change the old-fashioned and weak Emco steppers and drivers found on a stock lathe to modern steppers or servos, which is quite inexpensive and easy. I'm going to rebuild my lathe to use small 100W Yaskawa servos that can be easily and extremely accurately controlled by the Mach3 software, although I'll need to make new timing belt pulleys for the 8mm shafts on the servos. The stock stepper shafts are either 6mm or 6.35mm (1/4") in diameter, so the original timing pulleys can probably be used without too much machining on any decent stepper motors.

    It all depends on how much time (and money, perhaps) you want to spend on these machines. The basic iron is good, but the electronics is as obsolete as any 80s computer electronics can be. Lots of repairs to be expected even if the machine runs well now.
