Not sure I my experiences will be of much help to you, but I use an Orion on my CR-10S S4. I designed the mount myself, it's similar/remixed from to a popular one on Thingiverse. Mine however is magnetically attached for quick changes. The Piezo probe was really fussy to get setup... But once I got it working it's been extremely accurate and reliable for me. Note my F850, I needed to come in pretty fast for best results. The most frustrating part for me was getting the preload/stress on the Orion PCB just right.
I probe with everything hot. I refine my first layer with babystepping.
Here is my config code:
M574 X1 Y1 S1
M574 Z1 S2 ; Set endstops controlled by probe (Z-endstop is Z-probe)
M558 P8 I1 H2 R0.5 F850 T6000. ; Set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height
M557 X0:390 Y0:370 S20 ; Define mesh grid
