3.5b3+MB6HC+Smart Effector Probe Triggering at Standstill

blt3dp

This behavior seems to be software specific. I updated to 3.5 b3 to resolve the web interface continuing to report the prior filament out condition. That was resolved, but I noticed that the z probe seems to be triggering at standstill since then. Here's M122.

And here is my config.g

; Z-Probe
M558 P5 R0.4 C"io4.in+io4.out" H5 F300 T1800              ; set Z probe type to effector and the dive height + speeds
G31 P100 X0 Y0 Z-0.05                                     ; set Z probe trigger value, offset and trigger height
M557 R110 S20                                             ; define mesh grid

Cause of this, my normal calibration doesn't work.
Is there something I can adjust to take care of it?

@blt3dp when the machine is at standstill:

Is the green LED on the Smart Effector flashing?
Is the Z probe reading in DWC changing between 0 and 1000?

Looks like not specific to 3.5 b3 like I thought, I rolled back to MB firmware 3.4.5 and DWC 3.4.5 and it's still doing the same. The light on the smart effector is flashing. I see varying numbers in the web interface, 0, 312, 500, 625, 1000 are the ones I recall.

Edit, I also unhooked the filament sensor and commented it's line out of config.g
Edit again, it's also a v2 Smart Effector

It's fixed, turned out it was my cabling. I must have tweaked it somehow when I installed the filament runout sensor. Crimped a whole new set for the 8 pin and is all good now.
