BLTouch was working and now isn't.

So i had a month or so not using my printer, went back on today and tried to reset the bltouch pin using a macro.
M280 P3 S160 I1
it returns;
M98 P0:/macros/Reset BLtouch
Error: Invalid servo index 3 in M280 commandNothing has changed in my config so i have no idea what has gone wrong.
M307 H3
returns
M307 H3
Heater 3 model: gain 340.0, time constant 140.0, dead time 5.5, max PWM 1.00, calibration voltage 0.0, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P13.4, I0.482, D51.4
Computed PID parameters for load change: P13.It's a pain as i am keen to get printing again.

It sounds to me that the command M307 H3 A-1 C-1 D-1 is missing from your config.g file.

M307 is there however i had it configured to this
M307 H3 A465.7, C176.6, D3.2 S1 ;

@dc42 said in BLTouch was working and now isn't.:
M307 H3 A-1 C-1 D-1
so i changed it to M307 H3 A-1 C-1 D-1 and it seems to work, cant remember why i would have it set differently?

Try this it worked for me for some reason.
M307 H7 A-1 C-1 D-1 ;
M558 P5 X0 Y0 Z1 H9 F200 T6000
