    G'Day Andy and welcome sounds like you have the right attitude mate. "If you can imagine it, you can create it". I think you might like it here and are looking forward to what you come up with.:)
    May the imagination stay with you.

    Failures???? There are no failures, just good reasons to try something another way. ;)

    As an AutoCAD user, how am I able to upload dxf or dwg files? The system will not let me.:(

    Don't know if I can help you there Andy. I'm a Fusion 360 user and not familiar with AutoCAD. All I can suggest is to take a screen shot and upload that. Someone else might know.

    I think you are missing a step, you don't upload dxf files to the controller, you have to convert them to g-code then the controller does the rest.

    Hello, The thing that you call a break out board, isn't that a 4 axis usb controller that does not require drivers because it already is a driver? The reason I ask is I am considering purchasing one of those controllers for my wife's machine and I was wondering how it is working for you. Also, what software are you using to operate the device? Are you using mach3?

    Thanks for the message, I have only just started my build and taking things one at a time. I am using a USB CNC 4 Axis Controller Interface Board with 3 Single Axis TB6600 boards. I am not sure about drivers yet but from what I have gathered it is a Chinese clone of the PlanetCNC controller. It is driven by a PIC chip that I assume has been programmed as necessary, so I hope this answers your question.
    When I have finished the build I am thinking of using EMC2 as the software. If you are thinking of Mach 3 it may be worthwhile considering Mach 4 as I believe it supports USB ports.
    To date, I have used the board to run one stepper by using the onboard jog control so I am now going to make a remote control (using my 3D printer) that will control the axis jog direction and speed together with the obligatory "Oh sh*t" stop button.
    As the unit will be in a metal case, I am adding external LEDs to indicate pulses to the TB6600 boards.
    My build is a voyage of discovery for me and I hope I have given you enough information and welcome any suggestions.

    Hi,
    I have yet to decide the type of machine, whether C beam, OX or whatever, I intend to make. All have their advantages and disadvantages. Software is another minefield, but I am tending towards EMC2 and running it on a laptop using Linux. The motors I have for the final build are Nema 23s rated at 2.8A, power 175oz (12.6kgf.cm).
    I am currently concentrating on the electronics side of the build with the associated testing. This will be followed by testing the software on a 3 axis rig (that is after I have learnt how to use it properly!)
