BL-Touch doesn't work via Tool Board V1.0

ELAD

Hello,

The BL-Touch doesn't light its LEDs and does not obey any Gcode commands.
I can see on the DWC it changes from P1000 to P0 when physically connected, but that's it.

Here is the relevant part of the config.g

; Z-Probe___________________________________________________________
M950 S0 C"20.io0.out"									; create servo pin 0 for BLTouch
M558 P9 C"20.io0.in" H5 F120 T90000						; set Z probe type to bltouch and the dive height + speeds

and here is M122 B20

I would appreciate any support, if further info is required, please let me know,

@ELAD if the bltouch doesn't even light up or do the startup deploy and retract then you have a wiring issue

ELAD

@jay_s_uk

The tool board functions perfectly except for the BL-Touch.

@ELAD looks like your wiring is back to front.
5v is the opposite side to the heater output

@jay_s_uk
Thank you very much. The wiring indeed was the issue. I am a bit embarrassed I couldn't notice it.

@ELAD don't worry, we all get cable blindness sometimes!
