    Hi Everyone

    So previously I used Mach 3 and this was with a shopbot machine to run my files and cut my jobs and now that I've moved over to openbuilds I'm hoping to run my current files but understand that there are some changes to be made.

    I creat all my gcode ( .tap ) in fusion 360.
    So today after managing to run the new firmware dew to a python problem I got everything to work however it seems maybe I need to make change to my files.

    Error 20 came up stating " unsupported or invalid g-code command found in block ( GO Z136.742 )
    I also noticed my files still show the mach3 in post-processor.

    1. does openbuild prefer a different type of gcoode
    2. is there a preferred software in post-processor I should use.

    any help would be great.

    GRBL, the software in the BlackBox, does indeed prefer some things different to the Gcode Mach3 likes, so using our postprocessor is recommended.
    important diferences are
    no toolchange codes please. (this will change in the future but for now, avoid)
    no toolpath offsets, you must select 'in computer'.
    always home the machine.

    HI David

    Thank you for the feedback.

    Can you just clarify the settings as you have suggested. Would I change this in fusion 360 . I don't see a option for " in computer "

    Kind Regards

    Wesley

    yes in Fusion360, , in the options for each cut there is a section for 'compensation' with options for
    in computer
    in controller

    in computer generates the path where the cutter must move, using the cutter diameter + 'radial stock to leave' as the offset. We want this.

    in controller uses G41/G42 cutter compensation and the path is programmed along the PART edge, and controller must know the size of the cutter to offset to left or right of the given path.
    GRBL/Blackbox does not understand this code. We do not want this.

    Fusion 360: Equivalent of Carbide Create "No Offset" contour

    Hi David

    Ahh ok I've seen that this is only if you're cutting a contour - I'm cutting a morphis spiral and this option is unavailable. see image attached.

    Would this still require this setting ?

    Kind regards

    Wesley

    if there is no setting, then you dont need it (-:
    exact radius of cutter will apply mostly to finishing cuts, for which a morphed spiral is not used.
