    Alden, I ran into the feed rate arc bug myself this morning (was driving me crazy thought I’d messed up my gcode).

    So I updated to 435.08dev and it worked flawlessly. Thanks!

    Aha!

    Looks like the firmware was wiped or something, your hint about the flashing CW/CCW LED did the trick.

    I figured it must be in ‘waiting for firmware’ bootloader mode, so I ran the AVRDude command from the wiki and installed the latest firmware and all appears to be good now!

    Thanks for the help guys, not sure what happened but I guess the firmware got corrupted somehow.

    Here’s the steps I’ve taken and results seen:

    1. Power board
    Result: Blue LED lights, Fan starts, Spindle CW/CCW LED lights continuously.
    2. Hit reset
    Result: Spindle CW/CCW LED starts flashing and does not stop.
    3.Connect via CoolTerm with baud 115200
    Result: Connects, no output.
    4. Hit return a few times
    Result: Only see ? as response
    5. Send ‘h’ or ‘?’ or ‘$’
    Result: See single ? for ‘h’, for ? or $ we see a ?? response.

    Hitting reset again returns to flashing Spindle CW/CCW LED.

    If the constant flashing CW/CCW LED is an indicator of bootloader mode then I guess thats where I’m stuck at, perhaps the firmware is missing?

    Additional info…

    The board appears to be running 370.08.

    If i type CTRL-X at the terminal the Spindle CW/CCW light toggles on/off.

    At startup the Spindle CW/CCW light blinks…it was blinking 10 times then outputting the above JSON response, since further fiddling at the console I’ve evidently changed something since now it just blinks perpetually till I type something into the console and I no longer get the nice startup JSON message.

    I have noticed that the LED next to the mark ‘tx’ flickers when I type at the console, while the ‘rx’ led flickers (or at least did when it worked) when the startup message is sent. Shouldn’t these be the other way around?

    I’m running Windows 7 64bit.

    I have tried connecting with PUTTY to the same effect. I have tried every other USB port on my PC to no effect, and on a mac book pro.

    Have I got a dodgy board?
