; Auto calibration routine for delta printers
; Before running this, you should have set up your zprobe X, Y and Z offsets to suit your build.
; This does a single iteration of auto calibration. Run this file multiple times until the values converge.
; Then transfer the values to your config.g file.
M561 ; clear any bed transform, otherwise homing may be at the wrong height
;G31 X0 Y0 ; don't want any probe offset for this
;G28 ; home the printer
;*** Remove the following line if your Z probe does not need to be deployed
;M98 Pdeployprobe.g ; deploy the mechanical Z probe
M201 X500 Y500 Z500
; The first time the probe is used after deployment, it gives slightly different results.
; So do an extra dummy probe here. The value stored gets overwritten later.
;G30 P0 X0 Y0 Z-99999
; Probe the bed and do auto calibration
