Z Probe shows 1000

vapvap

After installing the "Flex3Drive" extruder on the smart effector, when the "hot end" heats up above 90 Deg, the "Z Probe" starts to show "1000".

; Z-Probe
M558 P5 R0.4 H5 F1200 T6000 ; Set Z probe type to effector and the dive height + speeds
G31 P100 X0 Y0 Z-0.1 ; Set Z probe trigger value, offset and trigger height
M557 R90 S20 ; Define mesh grid

Please tell me how to fix this?

Sound like a wiring problem, or interference.

@Phaedrux At first I also thought it was a wiring problem and changed the tips on the wires. But nothing has changed...
In addition, I assembled the extruder according to the instructions from the official website without any improvisation...

After several experiments, I noticed that if you turn off the cooling fan "Z-Probe" returns to normal.

@vapvap

that means the vibration from the fan trigger the smart effector.

try reducing the sensitivity
