    Hello. I hope I'm not missing the obvious but I've searched the web high & low and can't seem to find a single breakout board that is fully compatible with the UC400ETH -- that is one that supports both parallel ports. Can anyone recommend a compatible bob? I'd really like to give the UCCNC platform a try.

    Other than the UB1, the only multi port breakout boards that I know of are for the Smoothstepper. And they are all about $150 or more.

    You can always use two inexpensive single port boards.

    If you really want a single multi port board, then it makes more sense to get a UC300ETH and a UB1.

    Thanks for the quick reply/info!
    But that's kind of crazy, right? What use is the UC400ETH if there are no breakout boards for it? Is it a brand new product or something? Yes, I can cobble together a couple of single parallel port solutions but that's a kludge. I thought the smooth stepper C25 would be the perfect solution but discovered that the 2nd parallel port is not "standard".

    Absolutely ANY BOB that connects to a standard PC parallel port, which is MOST of them, will plug connect directly to the ETH400, or ANY UCNC motion controller, with a simple ribbon cable. Why on earth do you think you need a single board that plugs directly into both ports?

    Teh UC400eth has 2 standard LPT type1 port configuration. 12 outputs and 5 inputs each.


    Any bidirectional breakout board will work with it as well as the type 1 only lpt BOBs.

    IF you want a single board then most boards for a Smoothstepper will work fine

    Just a thought, (;-)TP

    Because I'm tight on space and that would be the most elegant solution. Guess it's not absolutely necessary.

    As I mentioned, the C25 does *not* work as it appears the 2 LPT ports are hardwired--one is UC400ETH compatible, one not. But yes, I'll check for boards that are bi-directional.

    Aren't you making a hen out of a feather? I mean, why is it such a huge problem if you need to use two bobs?

    Actually, the "bi-directional" features of a bi-directional board are what won't work with a UC400ETH.

    Most 2 port boards have the second port as the bi-directional type, to get more inputs.

    MY understanding of Bi Directional is that the signal can pass thru in both directions. As an input or as an output. So it did not matter if you use it on a type 1 or 2 lpt port.

    Yes, but the UC400ETH ports are one directional. So a bi directional board on a UC400ETH can only be used as a "standard" breakout board, with pins 2-9 as outputs only.

    OK what does that have to do with the BOB (;-) If it is bidirectional then you set teh 2nd port on teh bob as a type1 and there you have it. You would have a BOB that is setup for 2 type1 ports.

    But not all 2 port BOBs are bidirectional.
