    Remote stop / go switch SWI cnc

    Hi all,
    I am looking for a used remote stop / go switch for my prototrak cnc milling machine.
    I assume that it is the same for most retrofit models.
    I have the Trak AGE 2 model.
    Thanks,
    Tom

    Have plans - can email

    Hi Tom in NH

    I have built several of these switches for our machines - I can send you details on what I have done if you would like - I have all the internals and you can make the case to fit however. Let me know!

    Diagrams

    Corndog - I can send you a sketch of the electrical hookup and the mechanical that I have - Are you wanting to make a complete unit or just rework some existing parts? Reason I ask is we had fixed ours for several years, but eventually the switches started failing, and the wires too - so I have actually bought connectors and pins and the crimper to make up new cables, and I have a very nice microswitch that is sealed too.

    Let me know what you need.

    I have made and use a remote switch that is connected to the quill and sends a signal to the control to go to the next position when the quill is returned all the way to the top. Much handier and faster than reaching for the button every time you want to move to a new hole location. Pretty simple to use, just disconnect the original remote and connect this one when you have a bunch of holes to spot, drill, tap, etc... I cut 30% off of a 3000 hole job a few months ago. $$$ I'm thinking about making some more and want to know if anyone would buy one and what would be a reasonable price. The first one paid for itself threefold on the first job. I think I can sell them for $75 plus shipping.

    Hi Jkruger, I'm very new to this cnczone so I hope this message gets to you. I am interested in getting one of these switches. I have an LX2 controller on a 1745P lathe. Older one, around 1998.

    Do an ebay search for 206429-1 . there is some very inexpensive stuff there or go to allied electronics with the same number. You will need pins and a clamp also. i have everything you need (connector, pins, cable clamp) if that is easier for you.

    JKruger,

    Thanks for the info. We should have what I need here. We have an electronics dept. I just needed the manufacturer, but this is even better. Thanks a million!

    Re: Remote stop / go switch SWI cnc

    Sorry to dig up an old topic, but do you have the pin numbering for the stop/go switch?

    (I'm also looking for the pinout of the 14pin SWiI Q input (Z scale) if anyone has it)

    TIA

    Bill

    Re: Remote stop / go switch SWI cnc

    BillTodd,

    The wires from handle are installed into pins 1 and 4 of the Amphenol connector - they are not polarized, so either wire may go in either position

    I do not have info on the 14pin Z scale connector - sorry!

    Re: Remote stop / go switch SWI cnc

    Thanks ATscuba .

    I took the cover off the encoder end of the motor and traced the wires of the X axis (I assume the same pins will be used for all axes) .

    I'll report back if all works as expected :-)

    Re: Remote stop / go switch SWI cnc

    Just to provide a bit of useful info (not much SWI info in the web)

    I have the Quill dro working now. The default settings are pretty accurate using an Easson 5um glass scale. There is a conversational scale calibration option (code 123) that asks you to set up a test using gauge blocks.

    The SWI prototrak Axes use 14pin AMP circular plastic connectors(CPC) by Tyco Electronics

    Axis pinout is
    1 - Encoder /B (wire colour yel/wht)
    2 - +5v (Red)
    3 - Encoder B (yellow)
    4 - 115vac to servo amp (black)
    5 - Screen ground
    6 - 0v Servo ground (Red/Wht)
    7 - enable (?)to servo amp (blk/wht)
    8 - 115vac to servo amp (white)
    9 - not used
    10 -PWM to servo amp (brown)
    11 -/PWM to servo amp (brn/wht)
    12 - Encoder /A (org/wht)
    13 - 0v Encoder (Black)
    14 - Encoder A (Orange)

    Stop / Go switch uses a 4pin AMP circular plastic connectors(CPC) by Tyco Electronics

    1 - Switch contact (normally open - should have some deboucing filter)
    2 - not used
    3 - not used
    4 - Switch contact

    Re: Remote stop / go switch SWI cnc

    Looking for information on the remote stop and go switch for ProtoTrak MX2 control. I would like to buy the components and make myself or purchase a complete switch. Mine was missing when I recently bought the mill (WEBB). Any help or leads would be appreciated!

    For information on the wiring see my post in this thread from Jan. 2013 - I have a diagram of the wiring on switch
    I have and can send you a BOM list of parts that I have used on switch units - the OEM units from SWI are approx $200 or so - but they don't hold up too well and maintenance on them can be challenging (they have a threaded fitting on the end that you have to tighten down and the wires get twisted some when you do that)
    PM me if you would like details and I will send
