[RRF1.17e] Bed leveling with M557 or bed.g?

I know, it sounds like a firmware question, but it's related to CoreXY.

I've installed an inductive Z-probe and it works as z-endstop and z-probe as well.
I had a hard time to find uptodate information about RRF and bed leveling.

G32 is a dead end?
Wiki says: M557 is deprecated in RRF and to use bed.g instead.
But what would bed.g look like?
On escher3d.com is a bed-file generator for deltas only.
Do I have to specify a giant list of M557 probe points or can I use M557 X0:300 Y0:200 S40??

Should I use G29 instead?
It sounds like the right way, but does it work for non_delta printers?
Also in G29 wiki there's no word about bed.g, it is about M557...

G29 is the modern way to do bed compensation with RRF. See [duet3d.com].

*crap*
I think, I toasted the probe input. I configured M557 very conservative the first time ( probe Y-offset is 80mm ATM ) and had 6 successful probe points.
Changed the grid to allow 12 points and probed again successfully. Then changed to 18 points ( three rows of 40mm distance ) but the zprobe input didn't trigger anymore.

I can see the LED on the inductive probe light up when triggered, but the input on RADDS ( servo PWM3 ) doesn't see anything. Even when I short it with a jumper wire to GND, M119 says not triggered.
The sensor is of NPN NO type, the same I use on my Prusa to pull down the z-endstop pin. ( no protection diode ). Seems the Due chip is less tolerant ...

The probe is in Mode 4, there is also Mode 5 and 6 I can try, but which pins on RADDS refer to E1 endstop or IN pin ( AD12 )?
Or can I use Z-min endstop?
