    Just finished a WorkBee1010 with a vPro3 and am using grbl 1.1.

    When I load a file into UGS and send it to grbl I am losing characters. For example;
    g code file line:...................................grbl output panel
    G54....................................................G4
    G1 Z-0.365 F355.6............................G1Z-0.36F3.6
    G17 G2 Y-17.773 J2.935...................G17G2Y-17.773J2.93

    This results in error messages like the following because of characters dropped.

    (error:28) G-code command is missing a required value word.

    (error:2) Missing the expected G-code word value or numeric value format is not valid

    (error:33) Motion command target is invalid.

    I am at a loss for where to start looking for the problem. ANY advice would be most appreciated!!!

    Hi Phillip, Check your sender settings.
    There is a truncate setting and a max command length setting.
    You can make the max character setting bigger to 80 for example with no problem, and set your decimal to 3 or 4.
    Not sure why it would lose the 5 on the G54.. Post a file here for us to look at.
    What cam program are you using for making the files?
    Are you using a GRBL post processor?

    also, use a quality and short USB cable. and keep it away from power cables.

    I think I have found my difficulty. Even though I set the baud rate in UGS at 115200, Windows 7 insisted on keeping it [at least some of the time] at 9600. Finally got Windows 7 to listen to my demands and the character loss seems to be under control. Thanks for the suggestions!
