G33 - 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.

Parameters


        G33
        
        
        [C<>]
        
        [E<|>]
        
        [F<>]
        
        [P<0|1|2|3|4-10>]
        
        [T<|>]
        
        [V<0|1|2|>]

`[C<>]`	If omitted iterations stop at best achievable precision; if set force iterations to stop at the set precision.
`[E<\|>]`	Engage the probe for each point.
`[F<>]`	Force to run at least n iterations and take the best result.
`[P<0\|1\|2\|3\|4-10>]`	`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.
`[T<\|>]`	Disable tower angle corrections calibration (`P3`-`P7`)
`[V<0\|1\|2\|>]`	Set the verbose level `V0`: Dry run, no calibration `V1`: Report settings `V2`: Report settings and probe results
