    have the issues with the g41 g42 been resolved . Last I saw on their forum - there were issues with it not creating a proper path and it was causing gouging

    At present it creates the SAME tool comp path as Mach3 ,Mach4 ,Acorn , etc . It is being worked on to eliminate the Gouge ( Fanuc style) OR throw an alert . I saw an ACORN toolpath of the same Gcode as UCCNC ran and it gouged as well. BUT these were also extreme toolpaths (;-).

    They are also working on teh ToolComp PrePost error messages.

    I can say it works extremely well (G41/42) deep inside ( 10 layers deep) of a subroutine.

    And UCCNC gets better every update (;-)

    I saw that .An error message would be good . I'm glad to see those being implemented . I've got an ethernet board and a couple uc100's that have been waiting on this option .

    Looking back, I guess what I posted was not very clear at all.

    A UC300ETH with 5LPT motherboard is indeed only about $25 more than a UC400ETH, and adds 3 ports + analog I/O.
    You'll need breakout boards with either one, so imo the UC300ETH is a much better option.

    If you plan on using an existing breakout board, then you want to buy the UC300ETH with a motherboard.
    The 5LPT motherboard is made by CNC Drive, and is what I would normally recommend.
    CNC4PC makes two other motherboards (M44 and M45), but I would not recommend them unless you plan on using a CNC4PC breakout board.

    If you plan on buying a new breakout board, then I would recommend the UB1, which is made by CNC Room in Thailand. It's not only better than any comparable breakout board, but it's cheaper than most. And it eliminates the need for the 5LPT motherboard, which makes for a neater package.

    Have any of you looked at the CNCPART.HU 5441 Board for teh UC300 ? It handles all 5 ports + extras. Prices don't seem to be too bad.

    The 5LPT is the basic option for the UC300ETH as I see, because the manufacturer selling the UC300ETH with the 5LPT board only. All others look like 3rd party boards to me.
    That gives you similar non-isolated pins like on the UC400ETH where you can connect breakout boards, the differenc is that the UC400ETH has less digital IOs and the UC400ETH has no analog IOs while the UC300ETH has.

    If you guys get interested in UCCNC for your Novakon machines I can set up a section over at teh UCCNC forum for you to use as a base.

    Thanks for the clarifications ger21 and olfcnc.

    I am confused on another point. I had thought that motion controllers such as Smoothstepper, and presumably also the UCCNC motion controllers, removed the need for a breakout board. And yet there is a breakout board option for the UCCNC motion controllers?

    Also, what would be a typical use for analog I/O on a breakout board?

    I still have the demo Mach 3 and have been trying to decide between LinuxCNC and PathPilot/Mesa board going forward.

    A motion controller is a signal generator and a breakout board is a signal conditioner.
    A motion controller communicate with the computer side software, get and send data and generate the signals to control your machine.
    A breakout board is to isolate and level shift signals.
    For example you can't drive a power relay directly with a motion controller output, because it does not have enough power and sometimes voltage to do that.
    You can have 24V or 110V or 220V relay coil which ofcourse a 5V output on a motion controller cannot directly drive.
    You need somekind of circuitry which convert, isolate for safety and level shift the signal for different voltage and higher power.
    You also cannot connect industrial sensors to 5V inputs on a motion controller. You can't connect for example 24V signals to 5V logic inputs. you need a circuit which isolates for safety and level shifts the signal to interface.

    What will you use with the analog signals. On analog inputs typically the feedrate and spindle speed override is controlled with potentiometers which you do not need any breakout board for you just connect potentiometers.
    For analog outputs you control the spindle speed via VFD and then again you do not need a breakout board because the VFD isolate the analog signal.

    Motion controllers come in many different flavors.
    Some simply have IDC headers to access their I/O pins. The Smoothstepper, UC400ETH, and UC300ETH fall into this category. You need a breakout board to "break out" the pins to make connections easier.

    Other motion controllers are combinations of breakout boards and motion controllers, having all the pins accessibly from screw terminals, and other functions. Most chinese Mach3 controllers fall into this category, but there are other high end controllers as well, like the CS Labs and Vital Systems Mach3/Mach4 controllers and the PMDX Mach4 controllers.

    A breakout board can also add functionality.
    The UB1, for example, has several added features.

    It provides 24V inputs and outputs for the UC300ETh, which is a 5V device.
    It provides 3 relays, which you can use for starting/stopping a spindle or other device.
    It has a PWM to 0-10V speed control.
    It has a charge pump output, which converts a charge pump signal to a 24V output.
    It provides differential step/direction signals.

    Thanks again to Ger21 and olfcnc for your excellent explanation of breakout boards and motion controllers.

    My mistake was that I had said I thought the Smoothstepper did not require a breakout board. I really had meant to say that the Mesa motion controller did not seem to require a breakout board.

    i will continue to watch this thread with interest. I can’t live with the demo version of Mach 3 forever. And I refuse to throw $175 at a cnc controller which is not being supported any longer. Especially with LinuxCNC being free and PathPilot/Mesa or UCCNC being only $100 more expensive than a license of Mach 3.
