@Phaedrux i was wondering if the deploy,and retract files look right.

M280 P5 S90 :retract bltouch -
Do they work? Are you using heater pin 5? You may need to invert the command with
I1 -
@Phaedrux i believe it is pin 7 or 8. heater 3 i hooked it up according to pic on website. but cant find wiring diagram.
-
@tdybare69 i get a m280 error no matter if i set it to 5,7, or 9 like everybody is recommending. really need help.
-
Did you read any of the links I posted?

You'll need to know what pin you're connecting to. You'll need to follow the directions to unbind that heater pin to make it available as a servo pin. And you'll need to format your deploy and retract commands to use the right pin you've chosen.

@Phaedrux thanks for that i have it on pin 8 like in the pic, wich is heater3.

@tdybare69 i really do appreciate you taking the time to help me

Well if you are using heater three then you need a command M307 H3 A-1 C-1 D-1 to enable use of PWM on pin 8 of the expansion connector - assuming you are correct that pin 8 is heater 3.
And in your M280 commands you also specify heater 3 use M288 P3 ### where ### is the servo position value needed by the BLTouch.
For example M280 P3 160 will clear a BLTouch alarm condition.
I put all the needed commands for configuring a Z-probe using a BLTouch in a file named configprobe.g. Then I call this file where needed.
This is what is in that file - I am using heater 7:
M307 H7 A-1 C-1 D-1 ; disable heater 7 to enable PWM5 - PWM signal still appears on E6 connector on Duex5
M558 P9 H5 F300 T6000 A5 S0.01 R0.2 ; set probe configuration - step 1
G31 X-44 Y0 Z1.350 P25 ; set probe configuration - step 2
M280 P7 S160 ; clear BLTouch alarm (if any)Frederick

@tdybare69 I reloaded dc42 frmware version DuetFirmware 2.03, then went into reprap configtool. while in there when i got to the endstop section before i clicked bltouch. i checked the box for deploy/retract option. then finished config. uploaded it here is my config

M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1side note B4138 is the default and is most likely wrong for your thermistors.
