BLTouch doesnt pin down

johny

BLTouch doesn't work after changing firmware from v3 to 2.05.1 (2020-02-09b1) (dunno why i had the 3. Bellow the config file:

; Endstops
M574 X1 Y1 S1 ; set active low and disabled endstops
M574 Z1 S2 ; set endstops controlled by probe

; Z-Probe
M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch
;M558 P9 C"^zprobe.in" H5 F100 T2000
;M950 S0 C"exp.heater3"
;M558 P9 H5 F100 T2000 I1 ; set Z probe type to bltouch and the dive
M558 P5 H5 F500 T4000 X0 Y0 Z1 ; Set Z probe type/mode 5. H=Dive Height. F=Speed the
G31 P50 X31 Y4 Z0.905 ; set Z probe trigger value, offset and trigger
M557 X20:200 Y20:200 S40 ; define mesh grid

Thank you

probably its a map error:
M280 P0 S10
Error: M280: Invalid servo index 0 in M280 command

Use P9 instead of P5 and remove the X0 Y0 Z1

Otherwise it sounds like you get it sorted?

Hello,
I got it sorted with the following changes on config.g
; Z-Probe
M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch
M558 P9 C"^zprobe.in" H5 F100 T2000
M950 S0 C"exp.heater3"
G31 P25 X31 Y4 Z0.905 ; set Z probe trigger value, offset and trigger height
M557 X20:200 Y20:200 S40 ; define mesh grid

Now i have a problem that i never got it solved, when i ask the heater tool 0 to heat up it never stops on the temperature needed, it keep increasing, what could be the problem? my config
; Heaters
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1
M143 H1 S280 ; set temperature limit for heater 1 to 280C

Are you using firmware 3 or 2?

Send M115 to see what you actually have installed.

On the temperature, example:

I ask for 150º and it keeps going up without stop. He stops when it gets the error
