    Default Breakout Board expandability….

    Hi All

    I will be using an Ethernet connected controller, (the UC300eth-5ltp*or the UC400eth*from CNC Drive (UCCNC). Both have a large number of I/O (36/49 & 24/10 respectively) and using the UCCNC control software.
    *
    Initial setup would be for a gantry router configuration (2 motors slaved together on the Y axis), a spindle & vfd, a wireless MPG, Up to 8 Limit/home proximity sensors, E-Stop and an auto tool height setter.

    Looking at the generally available breakout boards (€20 - €60 range), they have the following I/O
    ¥ 5 x inputs
    ¥ 4 x outputs
    ¥ 4 or 5 x stepper drive connections.
    *
    Both the UC300eth & UC400eth have a lot more I/O which will not be able to be used!

    Now my questions

    What are my options for making this configuration expandable beyond the initial I/O capability of the std parallel port breakout board?

    Do I need to look at dual port products like the PMDX-126, the C62 - Dual Port Modular CNC Breakout Board & the C32 Dual Port Modular CNC Breakout Board?

    Are the I/O used on the standard parallel port for stepper drive connections, (pins 1 through 12) able to be reused for another purpose?



    Can I use two of the std parallel port breakout boards in my electronic configuration (assuming ping 1 through 12 can be repurposed)?

    Thanks in advance for your advice.
    Regards

    A couple of C10 breakout boards give you a lot of flexibility, as the pins can be configured for both input and outputs.

    Or, an M44 motherboard, which has a variety of accessory boards with different functionality.
    Note that the M44 will soon be replaced by an M45 board, so I wouldn't buy one at this time.

    Hi Gerry,

    I've been trying to find information on the new M45 board you mention and come up with nothing. There is one called the UC300ETH-5LPT board though so would that be it?

    Another question, if using the UC400ETH, what breakout board would you recommend for that motion controller to utilize both parallel port I/O pins that are available? Not that I would ever need it, but the 5LPT board seems to offer more options/flexibility.

    Thanks,
    Ed

    No, the 5LPT is the standard motherboard made by CNC Drive and is what I'd recommend.

    I was told a few months ago that the M45 was about to be released.

    I since found that the M44 that I purchased did not work with all breakout boards, and possibly only with CNC4PC boards.

    I found a breakout board that had the features I wanted, the MB2 from CNCRoom in Thailand. MB2 ESS ethernet smooth stepper BOB breakout out board [MB2]
    I ordered it and a 5LPT motherboard.

    I did some quick testing with it yesterday, to make sure everything worked. While I haven't used it on a machine yet, I highly recommend it, and the UC300ETH.
    The MB2 uses 3 ports of the UC300, so you have a lot of accessible inputs and outputs, at 24V. The UC300 also adds additional analog I/O, which makes it easy to connect pots for Feedrate and Spindle overrides.
    And the UC300 isn't that much more expensive than the UC400.
    Note that the MB2 will not work with the UC400.

    Thanks Gerry,

    I'll be getting one of the boards in the near future, probably the UC300ETH-5LPT combination with UCCNC, and your screenset. My router is still a ways off so the only thing I could test it on now would be my Sherline Mill. I might give that a try just to get familiar with the software. In that case, I guess the only additional hardware I'd need would be a power supply and ribbon cable. At least I'd get some experience with it before the router is built.

    Nice job on the screenset, BTW.
    Ed

    A possible warning about using the MB2 with the UC300ETH.
    Both the UC300 and the MB2 supply 5V on pin 26 of the ports. There's a possibility that this could damage the UC300ETH, so I cut the wires for pin 26 in the ribbon cables I used (3 ribbon cables). You can also remove a solder bridge on the MB2 to disable the onboard converter that provides that 5V.
    I don't know for sure if this is required, but better safe than sorry.

    Hi Gerry, I have here the UC300ETH and the BOB card as you linked a few time past.
    You have test both cards together ? Can you place a schematic wires among them ? My parts are: 3 nema 23, 3 driver stepper DM542 how to make for wire all ?
    can you help?

    Because the UC300ETH can work only with a BOB connected, confirm me if I mistake...

    My first Idea had of use together cards

    Hello Gerry,
    Is it possible to use 2 or 3 ea ST-V2 BOB connected to 1 ea UC300ETH to get more IO ?

    Only 2.

    3 of the ports use pins 2-9 as inputs, so to use those ports you'd need a board like the C10. You could use five C10 breakout boards with the UC300.

    You could wire the ribbon cable directly to the drives, but I wouldn't recommend it.

    can you explain with a little drawing or picture same your formidable last post, how to make all wires of uc300 with ST-V2 with motors, drivers and power supply ? I need link the ST-V2 out terminal with drivers ? I need power supply both card with 5Volts ? I'm very confused

    Hi,
    What size of cable to use for the bob to driver or to power supply? I saw some drawing the white connector on the BOB are used but using very small cable, is it recommended?

    No, you set up the second motor as the A axis (or B, or C) and slave it to the Y axis in the control software.

    Only the power supply to motor drivers carry more current. Everything else can be small gauge, like 20-24awg.

    I have solved a little issue with the uc300eth. The uc300 without ST-V2 ,I tried connecting pin 10 e-stop and pin 25 gnd in connector uc300 port 2, it work. Then i have try put the flat on lpt port ST-V2 , i connect on terminal st-v2 e-stop and gnd, this not work and nor recognize the e-stop on match3. Can be the flat that not work ? What wired diagram lpt can work amog the cards ?
    I need know what connections cable flat make it among this cards..

    Do you have 24V on your breakout board? It's required for the inputs to work.

    No I need only check if the both cards comunicate among them ... the ST-V2 bob have a cable usb, and the uc300 have 5v power supply..I want test only the connections among hardware and Mach3 , but I believe that the flat cable in boundle on UC300 not good wired with ST-V2 lpt.
