G33 - Delta Auto Calibration

1.1.0 calibrationdelta Calibrate various Delta parameters DELTA_AUTO_CALIBRATION

Description

With the G33 command you can:

  • Probe a circular grid of points,
  • Calibrate Delta Height,
  • Calibrate endstops,
  • Calibrate Delta Radius, and
  • Calibrate Tower Angles.

Usage

G33 [C<float>] [E<bool>] [F<1-30>] [O<bool>] [P<|0|1|2|3|4-10>] [R<float>] [T<bool>] [V<|0|1|2|3|>]

Parameters

[C<float>]

If omitted iterations stop at best achievable precision. If set iterations will stop at the set precision.
    [E<bool>]

    Engage the probe for each point.
      [F<1-30>]

      Run (“force”) this number of iterations and take the best result.
        [O<bool>]
        2.0.9.2

        Probe at probe-offset-relative positions instead of the required kinematic points.
          [P<|0|1|2|3|4-10>]

          Number of probe points. If not specified, uses DELTA_CALIBRATION_DEFAULT_POINTS

          • P0:

            Normalize end-stops and tower angle corrections only (no probing).

          • P1:

            Probe center and set height only.

          • P2:

            Probe center and towers. Set height, endstops, and delta radius.

          • P3:

            Probe all positions - center, towers and opposite towers. Set all.

          • P4-10:

            Probe all positions with intermediate locations, averaging them.
          [R<float>]
          2.0.9.2

          Temporarily reduce the size of the probe grid by the specified amount.
            [T<bool>]

            Disable tower angle corrections calibration (P3-P7)
              [V<|0|1|2|3|>]

              Set the verbose level

              • V0:

                Dry run, no calibration

              • V1:

                Report settings

              • V2:

                Report settings and probe results

              • V3:

                Report settings, probe results, and calibration results

              Examples

              Default (Verbose 1)
