    Hey Guys! I hope you are all well?

    I am not a guru by a long shot and basically self taught everything I know about CNC machines.
    I bought a built machine from a local supplier and honestly had minimal support.
    It's a Lead screw machine with an Arduino board.
    Max travel distance : X - Axis = 716mm
    Max travel distance : Y - Axis = 695mm
    Max travel distance : Z - Axis = 50mm
    No Limit switches

    Now and then the machine hits alarms and a recent one said something about a Hard limit triggered.
    Looking at the 3D view it appears as though the work piece is next to the machine bed - screenshot attached.

    I was wondering if it is set up incorrectly under GRBL Settings?
    Looking at the axis Max travel especially (Screenshot attached) or does the 3D preview have absolutely nothing to do with what I have in here?
    I guess I need to know if this is why the machine hits alarms and triggers now and then?
    Having said all that, it is absolutely fine at least 70% of the time with no issues.
    I would value any input on this please?

    Install some
    Then HOME

    Then work coordinates cube will show where it actually is. Without homing machine has no idea where it is

    If you don't have switches, don't enable Hard Limits. Disable till you get some switches installed

    Hey Peter!
    Thank you for confirming that...
    I will do a Google to see how I can install limit switches :)
    Thanks again
