Question about delta auto-cal results



  • Hi,

    Being OC I've been working on getting my delta calibrated as well as possible.

    I ran the auto-cal procedure three times and got these before and after numbers.

    0.023 -> 0.019
    0.025 -> 0.016
    0.020 -> 0.018

    A couple of questions:

    Why does the 2nd run (just as example) not report 0.0019 -> 0.0016?

    What could cause the 3rd run to report a worse result (the 0.018)?

    Thanks.

    Frederick

    If the only geometrical errors in your build were things that auto calibration can correct for, then it would; but there are many other types of error that auto calibration can't correct for. See the list at https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer#Section_Make_sure_your_build_is_accurate.

    What could cause the 3rd run to report a worse result (the 0.018)?

    Small differences in the height at which the probe triggered. If you are using the Smart Effector or a piezo, P8 in the M558 command may give slightly better results than P5.

    Thanks much!

    Now how do I get rid of that "unsolved" marker on this topic?

    The solved/unsolved markers appear to have gone away today.

    I just need to refresh the page in my browser.

    All is good.

    Same here!

    If you click on the Topic Tools button, you should be able to select Mark as Solved.

    Found it - looked everywhere but there.

    Thanks.
