Strange auto calibrate map and heights



  • Hello everyone,

    So I am going through the config.g trying to sort out everything in my other post (Here).

    I am getting a strange bed auto calibrate map. Not sure what I have done, I changed the micro stepping from x32 to x16 as it was pointed out to me that x32 does not work. The delta is so smooth now, and according to the callipers moving the right distance.

    Please see attached image, I have never seen such a massive curve across the bed. As ever all help extremely appreciated.

    You have a delta printer but you haven't calibrated it. See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer.
