Improved Mini Kossel auto calibration file

Improved the macro file bed.g that gets run in response to a G32 command
to do an extra dummy probe at the start, and to do 2 sets of calibration
instead of just one.

-; 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.

-M98 Pdeployprobe.g			; deploy the mechanical Z probe

-; These must place the probe near the base of the X (left) tower, Y (right) tower, Z (back) tower, and bed centre in that order.
