Super PINDA 25 minute calibration
I just upgraded my Mini to a Super-Pinda (black tip replacing orangish tip).
I remember reading somewhere that there was a precise calibration process that took 20~25 minutes and did a 1000-point calibration.
My mini continues to o 9-point calibration and doesn't indicate anything to show that it knows the PINDA is "Super"?
1) Do I need to do something to trigger the 1000 point calibration? Or is the 1000 point calibration (that takes 20~25 minutes) only for the Mk3?
2) Is there a way to confirm that the Mini knows the PINDA is "Super"?
RE: Super PINDA 25 minute calibration
1) I'm not aware of any 1000 point calibration routine on the Mini. I think the Mk 3 does 7x7 point and can do multiple 'probes' per point, so may get to 1000 points.
2) The Mini doesn't need to know what what Minda / Pinda it has fitted as it's "just" a switch. The Super Pinda is more stable across the operating temperature, so it is more consistent when calibrating.
I have fitted a Super PINDA to my Mini and there is no change to the calibration process.

The Prusa Mk3 advertises a 32x32 (1024 point calibration) with the Super-PINDA.
I had assumed the Mini did this as well.
RE: Super PINDA 25 minute calibration
You can find the details of the new mesh bed leveling for the Mk3 on the GitHub pages here. The new algorithm uses a 32x32 grid for a total of 1,024 test points.
I don't see an equivalent entry in the Mini pages, so can only assume the feature hasn't been rolled out for the Mini yet. They may just be using the SuperPINDA as a MINDA for now.

Woo, doing a 32x32 before every print would be rough taking a half hour pre-print time... I couldn't imagine doing that just to run small prints or something.

In your opening you said 9 point, the Mini has a 4x4 - 16 point mesh bed level. The MK3 has a 3x3 - 9 point mesh by default, and a 7x7 - 49 point as an option. However, with the 7x7, 11 of the 49 are close to magnets and can throw them off, there's a magnet compensation that ignores those 11 for that reason. The new 32x32 seems a bit much, but I guess time vs REALLY level bed... I guess it's technically a shorter time than printing a safety raft.
EDIT: Checking the github, the new 32x32 is only for XYZ calibration, not the standard MBL procedure.
