I have installed this new firmware and I intend to do a calibration.
However, as explained in the image 210715 topic[forums.reprap.org], the deviation to commute the probe is not the same for the center of the bed and for the sides.
in the bed.g macro, RRP set no deviation for the 3 column calibration, then set a -0.2 deviation before probing the center, then set a deviation with G31 Z+0.1, which I assume lift the head by 0.1.
As we can see in the messages of the topic, this is a bit confusing, but if I well understand, the probe deviation is -0.1 for the near column (above springs) and -0.3 for the center. I checked manually that after the calibration, the 0 seems correct for side and center.
Also, in this SD image, they set a command G31 with z-0.1 in config.g, but I assume this is superseded by the calibration routine ? Or is it the pendant of the last G31 Z+0.1 in the bed.g ?

If I want to calibrate the printer with 7 points (or more), I shall set a deviation for each point, and somewhat calculate a deviation for points which are neither in the center nor near a spring. Is that correct ? There is some trigonometry to do here.

Then, I could run the 7 points calibration routine, (with 6 parameters calibration) till convergence, then enter the parameters in the M665 command in config.g.

G30 P2 X0 Y75 Z-99999 ; Z tower G4 P300 G31 Z-0.3 G30 P3 X0 Y0 Z-99999 S0 ; centre, and auto-calibrate G31 Z-0.1
