;M307 H7 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch
M950 S0 C"^exp.heater7" ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y40.9 Z.445 ; set Z probe trigger value, offset and trigger height
M557 X50:400 Y50:400 S100 ; define mesh grid x50:400 starts at 50, ends at 400 SXX moves by what its set to between points

nada.

Try M950 S0 C"exp.31" ; create servo pin 0 for BLTouch

tracar

@Phaedrux
no change

@tracar
how are you testing that it is working ?

tracar

@peter247

make the changes to config file, save ,reset board send command M280 P0 S10

Phaedrux

Does it do a self test on bootup?

tracar

@Phaedrux
yes

How is the probe when you send it extended or retracted ?

tracar

@peter247
does nothing

peter247

@tracar

Sorry , I was not clear what I was asking .
When you set M280 P0 S10 , was the probe extended or retracted ?

tracar

@peter247
afyer it does the initial test upon powering up, the pin is always up,

pin up or pin down commands do no change, it remains up

peter247

@tracar

Stupid question I know , have you checked the wiring ?
that all the wires are contacting ?

tracar

@peter247 yes. all good, even replaced with a new harness to test , all good

peter247

@tracar

Hell if I know what wrong !!
The only thing I can think of is changing the heater pin ,
with M950 S0 C"exp.heater7" and changing the physical pin.
But if it worked before I can see that working too !!!

i just dont get it either. i even reflashed the firmware, it works when i revert the firmware to 2x.
im at a loss on this one i think..

i can always work on the independant z axis for now

peter247

@tracar

yes H7_pwm on the end of the expansion board

Where are you getting H7_pwm from .
i'm using this diagram https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/vqBUAZPsxMC5tRgt.huge

pin 31 Heater7

here is another clue, after initial power up test bltouch goes in and out a couple o times, then i issue a bltouch test, where its sposta cycle in and out,,, well it does not..... but at that point i can unplug it , plug it back in and it wont do a self test.
