I am using Spring Steel spring bed with magnets underneath

Yeah - so am I - really like it but it means no more inductive sensor - back to the noisy BLTouch.

I didnt realize the magnets interfered with inductive sensors, how does prusa get away with it?

Perhaps they arrange the probe points to be away from the magnets?

Precisely this.

Easy? That depends on what you consider easy.

My first reply to you covered how to set the Z probe configuration to allow bed probing when there is no Z probe.

Setting m558 P0 and then using g29 as normal will ask you to manually jog the nozzle to touch the bed at each point.

Thank you @fcwilt & @Phaedrux I will give that a try

It works - I used to do it before I went ahead and installed a Z probe.

Have you considered a removable Z probe - then it cannot get damaged during normal operations.

If you are running a Duet 3 with the SBC, I have released an automated way to probe around the magnets and still get a valid heightmap:
