BL-Touch not work after update to 3.2

[Majk]

Hi Guys,

I need help with my printer, after update to Reprap 3.2 from Reprap 2.xx after that my bltouch won retract or detract. I think I forgot something to add in config g.
I using Duet2 Ethernet Reprap 3.2 and expansion Breakout Board. Bl is connected to heater7 pwm port on breakout board.

Thanks for help

@Majk said in BL-Touch not work after update to 3.2:

M950 H3 C"nil" ; Disable heaters h3-h7 to free up pins
M950 H4 C"nil"
M950 H5 C"nil"
M950 H6 C"nil"
M950 H7 C"nil"

this is not required

M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp

your thermistors settings is incorrect. find the correct beta value in your thermistors documentation.

Bl is connected to heater7 pwm port on breakout board

i think you need to invert the pwm signal for the breakout board

try M950 S0 C"!exp.heater7" ; create servo pin 5 for BLTouch

Thank you very much for the quick reply invert the pwm signal works. I searched for this solution about 2 days. lol
