    I am having a problem in that If i try to probe on th left front corner after i align the probe with the corner. I then confirm position and select probe. The gantry moves forward left then lowers the bit to air. Then i get an error. If i move the probe the the back right corner it works correctly. I am using a Zero2 xyz probe. I put the offsets in under the advanced setting. I have also selected different corners in the advanced setting to no avail. Any suggestions would be appreciated

    Including the error message exactly may give some more insight into why it errors

    Also sounds like your machine directions is incorrect, the first move is a X+ and Y+ move toward the center of the OpenBuilds Logo on our probe plate. If its moving forward and left, your X and Y directions seem inverted, see

    Thanks, So to confirm Y+ moves to the rear and X+ from left to right. While standing in front facing rear.

    Exactly like the buttons in control show yes

    Keep in mind all moves are endmill relative to stock (some machines like a MiniMill feels wrong because of the moving table design)
    Y- = brings endmill closer to the side of the stock facing the front of the machine
    Y+ moves endmill to the back of the stock
    X- moves endmill to left side of stock
    X+ moves endmill to right side of stock
    Z+ lift endmill up and out of the cut
    Z- pushes endmill deeper into the stock / deeper into the cut
