    assuming you keep pins 2 to 9 for controlling 4 axis
    Put my new handy dandy Klein multimeter [ cuz I broke my el cheapo Harbor Freight unit lol ] to the test, put one end on the 5v DIN rail power supply V- / GND and one the GND closest to PIN 1 - Beeep

    Moved the probe over to the GND between PIN 16 & 17 - BEEP ! So it seems commonality - I will check the LPT ports PIn assignment and find what pin the GND is on and check that further.

    Then this happens ... checking for continuity and doing my level best to keep this stuff "isolated" on the output into the C11GR from Power supplies AND out to the KBMM-125 - as per the manuals dire warnings.

    This may be supposed to be happening - Im not too sure ... kinda makes sense it would in one way - but then I really dont know if this is OK.






    yes your are correct about the pin 17 conflict

    relay 3 can only be controlled by either pin 1 or 17 (so pin 1 can only control relay 3 or the SSR ?)

    but the charge pump needs to use pin 17 !! ( had forgotten about that)
    Well PIN 1 is now wired to the SSR for coolant power and the Jumper is set for Relay 3 to use 17 AND .... SCHP jumper is set to Enabled - so I hope its ok as is. My luck - not so much.



    the PWM to analogue converter is connected to pin 14

    if you select international mode

    pin 14 also switches on relay1

    pin 16 can control relay 2 , which you can use for some thing other than reversing the treadmill motor

    John

    with my pipe dreams of using Mach3 and this board to magically reverse the motor shattered by reality and revelations gleaned here in this thread - Ive moved onto a forward only, uni-direction reality :-) I shall try and exist in a threadmilling universe devoid of rigid tapping [ for the time being ] ... So, that leaves me with Relay 2 and PIn 16 ...

    Honestly still havent been able to fully wrap my head around the whole US vs. Int'l Mode and why one even needs these two setups / configurations? Thats said based upon my situation here with ports pins and controllers etc ... you feel like my best option for this is the INT'L settings? Im really trying to understand their purpose - will do some research and C11GR manual decryption...


    Thanks again sir - gentlemen and scholar and all that ...

    I suspect the US v International thing is for historical reasons

    with 2 groups working independently in the US & UK
    I guess there was a 50: 50 chance they would decided to control the motor the same way or not

    first relay for forward and second relay for reverse
    or
    first relay for on / forward and both relays for reverse


    if the C11G has the same printer port connector wiring as the C10 BOB

    I would expect the metal shell and pins 18 to 25 to be connected to the negative 5V terminal and the printer port ground

    pin 17 is not connected to pins 18 -25 on the BOB as you normally expect but is used to detect the printer cable is connected


    John

    PS

    In the past I have had to double check when working on US made equipment
    like Ampex VPR2 one inch video recorders and Grass Valley vision mixers (you call vision mixers switchers in USA )

    the old UK mains wiring was red = live (240V) & black = neutral
    while the US wiring was white = neutral and black = live (120V)

    NOTE- the earth leakage currents will be reduced when connecting an EMI filter
    to the American 240V mains supply if your machine can be connected that way
    Flood Coolant... how to wire it?-emi-filter-jpg
    compared to the unbalanced US 120 or UK 240V supply
    Flood Coolant... how to wire it?-emi-filter-unbalanced-supplies-jpg

    here in the UK I don't know who the bright spark was that decided to adopt the european wiring colour codes

    but now 3 phase wiring has changed from red, yellow blue for the 3 phases plus black as the neutral

    to the new colours that are now brown , black , grey for the 3 phases and blue as the neutral

    OK unless the building has a mix of old and new wiring !!!!

    When you get your smoothstepper you can use a 2nd breakout board. So don't be too worried about running out of pins on this BOB. You can just get a cheap one without all the relays, charge pump, and 0-10v out. Like the c10s or c13.

    I have a C10 in my box o' goodies - I had no plans to use - LOL guess that could work eh ? Happy day!

    Ive got this one - it says C10 R 11.1

    Update 12/30/2017 : Big Boy Pantalone's ON - Controller Box Power ON - "It's Aliiiiive!"


    NO/None/Nada... wicked, not so magic smoke either !!!

    Hats off to all the kind gents who gave enlightenment, wisdom. confirmation, inspiration and had patience putting up with so many of my rookie DAQ's.

    SKMetal7
    CNC4XR7
    BIG BIG john-100 [ man ...what an ACE! ]
    Automation Technologies
    CNC4PC
    .. many others Im sure

    Humbled, Happy moment ... its all working and not smoking. Still a good ways to go yet but major milestone here...

    Spindle Key Lock out switch - works like a champ
    E-Stop - does its duty like a Boss
    C2 - 110v Contactor does too [ man that thing is kinda violent - lol
    Holding circuit / safety feature - rocks it - Sam - CNC4XR7 - you da man brother - great setup
    Remote Panel [ yellow rectangle box ] working good - needs a coolant on / off rocker switch / a 90* liqui-tight cable gland / and a DIN or other type plug to finish off a few loose wires... WOOT ... That thing is a Cable / Conducter-A-Palooooza


    Ive got a rather strong audible Clicking / Buzz coming off the C11GR BoB though - its Relay 3.... Which I may have a conflict due to the enabled SCHP - as it uses PIN 17 ... and Relay 3's jumper set to PIN 17 .... Relay 3 alternatively can be jumpered to PIN 1 [ PIN 17 or 1 are the only two options ] - but I have PIN 1 and a GND setup to control Coolant Power via SSR Relay.

    Something is funky though ... as - when I disconnect the KBMM-125s main AC Line IN to the KBMM-125 - the Buzzing Sound ceases. All this of course makes the assumption that this card is NOT supposed to be "buzzing" ...

    if you are using pin 1 for the SSR and pin17 for the SCHP
    the third option is just take off the jumper for relay 3

    John

    Thanks John ...

    Just tried that ... still buzzin. Jumper selector for Relay 3 - is bare - no jumper on it at all ... still buzzin.

    Red Light behind Relay #2 is lit RED.

    I have SCHP enabled atm ... and no Mach3 setup or connected at Parallel Port - DUOH! I shall disable SCHP for the moment and see what I get.

    more to follow...

    Thanks man

    SCHP disabled .. yields same results buzzing and red light on relay 2...

    Currently set INT'L mode ... gunna try US and see if that shuts one of these relays up :-)

    relay 2 and not relay 3

    2 questions
    how have you assigned the signals on pins 14 & 16 ??
    and have you set the jumper to US mode or International ??

    it looks like the C11G will become another project like the older C10 I did this from online photos

    Flood Coolant... how to wire it?-c10-o-jpg

    the circuit made it possible to see how it worked without having a board to test
    and add a resistor or two to answer a question when there was a conflict when most inputs required the jumper on pullup
    but one required pull down !!!

    john

    PS

    relay 2 is on in both modes when pins 14 & 16 are high (high is +5V)

    Ding Ding Ding ... we have a weiner !!!

    Switched the jumpers over to US Mode - nothing wired to Relay 2 so ... I guess my slow process of deduction and your ace knowledge of a smoke free environment ... ended up near the same place.

    She's no longer making a PEEP ! No RED light for Roxanne or Relay 2 ....

    Hurrrray !

    I think we have it sorted for the most part ... more voltage testing ensues and updates to follow.

    Well done Circuit Maestro John

    when the breakout boards relay switches off

    Hey John...
    How do you turn on off the relay on the C11. I want to use the relay that say Pin1 or pin17 controls it. So if I jumper the board to have Pin1 control it, do I just have Mach turn on Pin1 with the flood pump output...

    Hi truckeic


    I have not seen a C11G board close up to analyse as I did with the C10 board

    looking at the C11G manual the 2 relays are controlled by printer port pins 1 & 16

    Flood Coolant... how to wire it?-c11g-relay-control-pins-1-16-jpg

    manual
    C11GR8_2_USER_MANUAL.pdf

    so far I have not found any reference to removable jumpers to disable the onboard relays to use pins 1 &16 for other functions such as step and direction for a 5th or 6th axis

    you will need to assign pin 1 and / or pin16 in Mach 3 or what ever control software your using

    John
