    I bought a TinyG from inventables little while back (Late april/early May). When I got it I tried connecting it and could not get a computer to initialize it what so ever. It never showed in device manager either under USB device or ports. I thought maybe it just needed DC power to connect

    Well, I finally finished building my electronics enclosure with 2 fans, 24 volt DC power supply. Well to my dismay it still will not connect. I have tried connecting it to a desktop and 3 laptops. None of them even do the “DUN DUN’ when you plug in a device. I believe I got a bad TINYG. Is there anything else you’d like me to try.

    The power LED, Motor LEDS (brief slight motor humming in startup only) all shine. The TX/RX never do. Also the board will not power up via USB port.

    When connecting to 24vDC the spindle light flashes approx 12 times. Then green motor lights shine for about 2 seconds and the motors hum. Then the power light stays on steady.

    All the above looks correct. You can’t power tinyG from USB.

    The 12 x flashes of the spindle are the bootloader. When done booting, TinyG starts with all 4 motors held in current position (the hum you hear) for a settable period of time(depends on Motor Power parameters)

    If you purchased about 6 weeks ago, you likely received a V8 unit.
    Please verify. Might possibly be a V7; silkscreen on the pwb.

    To debug your connection issues, we need to know what OS (Win, MacOS, Linux) you are using.

    Did you read the section on the Wiki about needing FTDI drivers (FTDI is the supplier of the USB device used on TinyG)? Read thru this if not:

    Hi, it is a V8. Yes I read the above. I have the drivers from aruduino, usb to serial adapters, etc. Just in case I downloaded them but the system never acknowledges anything being plugged in. For instance when you plug the device in nothing changes at all in device manager. Between my laptops I have tested it on XP, Vista, and now Win 8.

    Well, if you are sure the drivers are there, and have tried a couple different USB cables, then I would sort of agree it sounds like a tinyG USB issue.

    Even without the correct drivers, I would expect an “Unknown device” sort of message in Device Manager.

    Inventables sent me a new board and I’m able to connect! If only I can find AVRdude to update the firmware 🙁

    You can find AVRdude in and Arduino IDE as outlined here in the wiki:

    https://github.com/synthetos/TinyG/wiki/TinyG-Updating-Firmware

    or here is a good tutorial on using AVRdude which give a link to WinAVR:

    http://www.ladyada.net/learn/avr/setup-win.html

    There were some reports that this clobbered the %PATH% on windows but I ran it on Win 7 and had no issues.

    It’s no longer distributed with arduino IDE. I downloaded the self installer plus zip file and even did a file name search. The help may need updating. I was able to find it on the developers website and with enough tinkering I figured it out.

    A simpler option may be needed to help get people going. It definitely wasn’t very obvious to me.

    OK, now that you can connect, what version of FW is loaded on your new tinyG?
    You may not need to immediately load new FW.

    How do you plan to load and run Gcode (Coolterm, tgFX, other)?

    Where to get avrdude? It is certainly not distributed with Arduino IDE as firmware update page suggests. I found somewhere avrdude version from 2003. Not sure if it is alright to use or not. Can someone suggest where to get up to date version of avrdude?
