    I have completed my build, and am now at the point of testing out the electronics / steppers. I am just attempting to get the machine moving and will eventually use it as a CNC router, and do not currently have plans to use it as a 3D printer. I purchased the kit from Vicious1 and have a Mac (yosemite).

    I’ve plugged in the steppers, the resistor on the T0, power, and usb. The board has a red light on.

    Under printing settings on Repetier-Host I don’t see a usb option.

    What am I missing? I’m a newbie when it comes to arduino/code/etc. so maybe I’m missing something obvious… Let me know if there’s more info/pics you need to help.

    Thank you!



    Mac settings are different. Do a search of these forums for “Mac”

    There are a few different ways to fix it I think. I do not own a mac to test it.

    1-reflash the arduino with a lower baudrate, make sure repetier matches it.
    2-different mac driver for the arduino.
    3-parralels to windows.

    There might be one more.



    Ok. I know how to adjust the baudrate on repetier but how do I reflash the arduino? Also, where do I find a different mac driver for the arduino?

    Thanks for your help!
