@WOPR73 You can just configure the SZP to be the first and only Z probe or K0 and do both initial and scanning operations. I got that to work but once in a while the printer would crash into the bed when doing the initial probe. Then I changed by bed from G10 to and PEI coated spring steel plate and then found I could not get the SZP calibrated to work as a initial Z0 finding probe at all. I broke down and installed a BLTouch to find Z0 as K0 and then the SZP as a scanning probe as K1.

@Phaedrux Only 1 so why am I defining it as K1. Duh.

@Phaedrux Well the default for K is 0 and this Scanning Coil Probe is K1 and not sure that can be changed.

@Phaedrux Thanks should have known using escape chars..

Don't include P if you intend to only change he speed. (Which seems insane by the way). You'd also need to include the K1.

Ah sorry the cut and paste dropped my :

That should have been

I got a little further by adding a Pnnn Trigger value to G31. But I get a Probe trigger before move error but the trigger value is well below the trigger point. I also realize you should use temp compensation but just trying to get it work first. Does anyone have any examples of using Scanning Z probes as regular Z probe?

I see as of 3.5.0-rc.3 a Scanning Z probe can be used as a Z-Stop? I am a bit confused as to how to do that.
I got it so somewhat work by touching the head to the bed and doing a G91 Z0 and then M558.1 K1 S2 to calibrate but I am sure I am missing something on how to correctly use it. Surely you don't have to set the Z0 reference to calibrate do you?

I have this in my config.g
