    Hi,

    I just set up my Interface this morning. I am able to move the machine and have gotten it to probe. However when I try to run the Gcode that I have successfully run through a laptop I get:
    GRBL ERROR!

    Error No: 1Invalid Gcode no letter.

    I double checked the GRBL settings on the Interface against the GRBL settings on the laptop and they match and I have opened the gcode on the laptop to double check it and it looks the same that I have run before.

    any idea what might be up? I use Meshcam from alibre to create my Gcodes and then edit them in Control so they will actually run properly on control.

    thanks

    Does the error consistently happen at the same point in the job, or at random intervals? If its random, check docs:blackbox:faq-emi [OpenBuilds Documentation] - (USB cables are a little more resilient than the long cable between Interface and BB)

    so far the few times i have tried to run it it happens right away. the machine doesn't move and the drill doesn't even start.

    would a copy of the gcode i am trying to run help?

    Line 1 "%" is not a valid GCODE Character. CONTROL strips out a few of the nonstandard characters, but Interface cannot filter, it just sends line by line. "%" is a leftover from when CNCs ran off tapes - use a modern CAM/Post that doesn't add it, for now remove it by hand
