  1. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    taken from the manual

    433818



    in addition to input pins 10 to13 +15 you have on the first printerport

    on the second printer port pins 2 to 9 are bidirectional that can be...
  2. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    from the photos I can see the printerport adaptor uses the MOSCHIP MCS98005V-BA

    433804


    on the photo of the C22 board I can not read the IC numbers but expect they are octal buffers like the...

    one problem with a machine built from anodised aluminium parts is the aluminium oxide film will act as an electrical insulator

    I have seen a few photos of Chinese machines with earth / ground...
  4. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    with the various LEDs coming on as you select different switch positions
    the next question is does the pin number next to the LED agree with pin you have assigned to that switch possition ?

    Re: BoB Board

    I have not found your BOB but this is very close

    433706

    433708

    it looks very like your BOB but takes a 5V supply from the PC instead of having a DC/DC converter to produce an isolated 5V dc...
  6. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    looking at the manual for the C22 Rev 4.3 pendant interface I see it has LED to indicate the state of the inputs

    do they confirm the switch status changes when you chang the switch positions ?
    ...
  7. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    From what I can see from the photos
    it looks like the wiring is correct

    the main thing is the printer port adaptor is set up correctly with pins 2 to 9 set up as inputs

    If its like the...
  8. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    As I said in post 68 unfortunately I don't have a definitive answer as to which adaptor works

    we need a member using a PCI card to give details on which card they have working

    as its 00:20 ...
  9. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    the 5V from two USB ports can power the rotary encoder and second BOB in post 23

    you can only connect the A & B outputs to 2 of the 5 inputs ( pins 10 to 13 + 15)

    433324


    To connect...
  10. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    It does look like your encoder is not working

    what current does your encoder take from the 5V supply ?

    John


    PS

    looking for a datasheet for a rotary...
  11. Re: Need help with npn n/c proxy sensor wiring!!

    how are you powering the BOB?

    433318

    if you have jumpers JN1 & JN2 installed so the same 5V supply is connected to both

    Vcc & Vdd that powers the input side of the opto-islators and ...
  12. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    OK
    powering a new rotary encoder from 4.94V

    when the outputs are not connected to any load


    stationary I have

    0.11V between 0V and A
    0.12V between 0V and B
  13. Re: Need help with npn n/c proxy sensor wiring!!

    If the Lj12A3-2-Z/AX NPN NC sensor has a an internal pullup resistor

    connect the sensor output to the BOB input via a 1N4001 diode just to make sure its not damaged

    the reverse breakdown...
  14. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    A meter with only a 300V DC range can certainly explain reading 4V
    as 4.99V will read 4V on the 300V range

    add a plus or minus one digit tolerance and the 5V can easily be displayed as...
  15. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    At best on the the 300DC range the reading will be plus or minus 1V , possibly plus or minus 2V

    so its not going to be easy to read the 5V supply with any certainty

    On the other hand your...
  16. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    After reading various posts about problems with printer port cards
    from what I can tell the results depend on the chip set used


    a few chipsets referred to in adverts

  17. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    One possibility is they have used the wires in an unusual way and not made
    the black wire 0V and red wire +5V

    In a ready made cable all that matters is the wires connect the correct...
  18. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    where did you take the 5V supply from ?
  19. Re: Need help with npn n/c proxy sensor wiring!!

    with this BOB

    433116

    you need to use sensors with open collector NPN outputs


    I have only seen N/C PNP sensors wired in series

    As you have enough inputs , I would connect 1 N/C ...
  20. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    set to EPP

    what do you see in device manager ?

    any thing like this windows 10 PC I use to connect to the internet

  21. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    I've had odd results with windows either not seeing new hardware or loading drivers correctly first time the PC boots



    Do you have a multimeter to check the 5V supply to the rotory...
  22. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    yes

    With the onboard port disabled
    and mach3's only port set to E000 (if thats what the motherboard & windows 7 sees it as )

    You should be able to set the port up to replace the onboard...
  23. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    I would disable the onboard printerport and set up the printerport adaptor as the "first" port at 278 hex
    then set it up in ports and pins with the setting you used for the onboard port

    with...
  24. Re: 3040-T ROUTER MAKING SPINDLE TURN ON /OFF WITH PROGRAM

    a USB cable as in post 49 is an easy solution that enables you to just plug into an existing external socket

    25pin D-type plug and USB plug to MPG cable

    if the USB cable joint is hidden...
