    Novice here, trying to get my first project to run correctly. Routing part of a case for some electronics, basically a rectangle cut out of a 1/2" sheet with a number of pockets milled into it. In the design, everything is squared up. In OpenBuilds CAM, I've opened an SVG and defined toolpaths. In the displayed grid, everything is squared.

    I send the GCode to Control and run in to my Leads 1010 and the result is skewed CCW by several degrees... that is, the lower left corner is < 90 degrees and the upper left corner is > 90 degrees while the two vertical sides are paralllel. This skew carries through the entire project, so all of the pockets are also not squared.

    It seems as though I must have set something undesirable... but I don't know what it is. Any help appreciated!

    Thanks in advance.

    Hi Paul, Pictures would help as I'm not sure what you are describing? did you go though the calibration?
    Post your settings here, and the drawing and code if you can.
    Thanks
    Gary

    Thank you for the reply Gary. Through simple lack of experience I did not think to check the machine physically, and suspect tomorrow I will find that the gantry is itself not square.
    Regards,
    Paul

    Is this what you are getting Paul?

    Looks like you either need to rack the frame square if its not at right angles in the four corners of the frame (check with a square or measure corner to corner), or...If that's ok, unplug the Y motors and turn the leadscrew (using the left side flexible coupling) to pull the gantry back a little or move the right side to push it forward. What you are trying to achieve of course is a gantry dead square to the Y axis.

    Yes, exactly correct on all counts. Having squared the ganty up milling four holes in a square pattern and equalizing the diagonals, all is well. Thanks!
