    Good afternoon.
    See attached screen shot. The gray wireframe box. I assume it represents the machine’s work area? It is dislocated from my job toolpath outline. Is that a problem?

    I turned everything off and back on. Re-homed all axes. Zeroed X/Y at front left of workpiece, Z at the table surface.

    Thx, rink.

    It does show the Machine Coordinates

    But in your screenshot, either you
    • didn't home,
    • or homing isn't setup up correctly ($23 Homing Dir, Max Travel, etc),
    • or you didn't Home first, then SetZero,
    • or SetZero incorrectly.

    Thanks, Peter.
    • I did home.
    • Attached screenshot of my GRBL $23.
    • I homed first (as I always do upon startup), then zeroed.
    • I set zero correctly at the front left corner of the workpiece, using the OB probe.
    The job ran correctly, as all my jobs have so far. Homing works correctly, at the back right corner of the machine. Jogging is all in the correct directions. Zero probing works correctly.

    What else can I check?

    According to $23 all your switches are at Axis Maximas - is that where they are on the machine?
    Full Grbl Setting backup would be easier to review (Backup Settings button on CONTROL > Grbl Settings tab) along with pictures of your machine

    Yes, the switches are at top, back, right. I'm attaching pics and GRBL backup, and photos of the machine in home position.

    but

    Kicked off with a LEAD1515 profile but lowered the Max Travel values?

    1515s Max Travels should be:


    (Hard to confirm if its a 1515 or not from the pics?)

    Yes, sir. It's a LEAD 1515 which you guys shortened for me. Y-axis 1000 instead of 1500. Those max's are what I determined from jogging the machine, and then subtracting the 5mm that the homing cycle backs off.

    OK, then Homing and Max Travel should be correct.

    After homing, GOTO Machine Zero (G53 G0 X-5 Y-5 Z-5) - you should be just shy of the top right corner of the gray cube?

    No sir. The pointer is in the lower left quadrant of the gray cube. See pic. If I ignore the gray cube, the pointer is about where it should be in relation to the work coord zero. And jobs run ok. So, it seems the gray cube is simply mislocated in the simulation window.

    And between the last couple replies, I've turned it off an back on, so whatever is happening is persistent.

    BTW...I know it's late in SA. And this is not urgent. Feel free to defer this until your convenience.

    Well, since your'e curious...OB Control is also doing something else unexpected...

    When I click Pause to pause a job during running, it pauses, just as it should. When I click Resume, it resumes, just as it should...but only for a couple secs. About two secs after resuming, it spontaneously pauses again, the button changes to "Resume", and I have to click that Resume again. Then it continues on normally. Not just a time or two, but every time. I've learned to work with it and I figured it was probably known and would be fixed in some future update, so I haven't said anything.

    Do you think it would it help to re-download OB Control and reinstall?

    I don't think a reinstall would help. But pausing can sometimes be a bit unstable - some old bug we've been chasing for a couple years. So less of a surprise than the offset on Machine Coordinates

    Good afternoon.
    Still happening. See attached. Not causing me any problems, just keeping you informed.
    Thx, rink.

    Post a fresh Grbl Settings Backup please

    If I load your last backup from the other day onto an X32
    - Home it
    - Run
    It ends up right where it should


    See, Blue current position indicator cone, just shy of top-right corner of gray cube.
    upload_2024-2-29_22-23-6.png

    If I do

    G53 G0 X-1190 Y-795 Z-95

    I am at front left bottom corner as I should be (Those are your Max Travel values)

    upload_2024-2-29_22-26-45.png

    If I then SetZeroXYZ, the grid comes and joines me there too

    upload_2024-2-29_22-27-37.png

    So lets see if you had different settings on the controller, than the backup you have us before

    Hey Peter, thanks.
    I haven’t changed any settings (that I’m aware of) but I’ll make another backup and send it as soon as I can.

    Hey Peter, sorry for my long delay. Here's a screenshot from today, along with a grbl backup from today.

    I connected the BB to my laptop, opened OB Control, and homed all axes. Then I loaded this g-code file, snapped the screenshot and generated the grbl backup.

    Thx, rink.
