    Hey there guys,
    I am quite new to tinyG and am looking for some help on if it is possible to read gcode from an sd card or usb drive that is attached to an arduino and then sent to the tinyG board.
    Thanks for the help in advance.

    I’ll say, in theory, yes it could be implemented..

    You would need to develop a sketch for the arduino that would handle the serial I/O to the USB port which you connect to tinyG.
    I have not seen anyone trying, but that does not mean it has not been implemented.

    If small is your goal, a RaspbPi 2 might be easier to implement – since it is running Linux you could port something like UGS over to the Pi.

    Have fun

    Thanks for the quick response. What are the basic steps to porting UGS (g-code sender?) to the RPi.

    My initial guess would be that you need do nothing, aside from setting up your Pi so that your can run command line files from your host PC.
    I run linux, so that is trivial.
    Of course you will have to install UGS on the Pi.

    If you run Windows, you might need to research how to use it as a command line client for Pi.

    The idea right now is to eliminate the host pc after getting this all set up and just run tiny g with the pi. Do you think that is possible? or will the pi still need the pc?

    Possible? Most likely, yes.
    The host(PC, could be tablet or even phone) is primarily to view messages and interact with command line interface, a debug port. I have seen some folks working to fashion a DRO using various Pi display shields.
