    I use grbl_0.7d_chamnit_328p_20111111.hex, and the OttoHermansson G-CODE sender https://github.com/OttoHermansson.

    ciao

    Hi Riley,

    I don’t know if is the same problem, but i have fix the connection difficulties with my pc and GRBL 0.7.

    the same system (same pc, same arduino and same g-code sender) work just with GRBL 0.6.

    I don’t know if is my operative system, my ftdi drivers, or my g-code sender, my arduino2009… but now it work! 🙂

    I thought it useful to explain my experience with a problem of grbl communication.

    – sorry for my poor english 🙁

    ciao!

    hello to all,
    I have fixed this trouble: I use the arduino2009 and with the GRBL 0.6, arduino working proper with the USB connection, but with the GRBL 0.7 the USB link don’t work!

    I have fix this, connecting the arduino RX-TX pin, to my RS232 by an ST232 circuit based.

    I don’t know because this happens, but I find the solution whit this action.

    It work fine and is very convenient (for my) to use an hardware port to send the G-CODE files.

    In this case you must to connect the arduino to an external source to power on it!

    Ciao!
