Duet 2 Wifi Bltouch isn't working.
-
Hello people on the internet,
I have a problem with the duet 2 wifi V3.2.2 it has a expansion breakout board V1.1 and a bltouch V3.1.
When I turn on the duet 2 wifi the bltouch does the self test but, when I send the M280 Px S10 code nothing happens. Also the M280 Px S120 code doesn't work. I have changed many things in my config code but nothing seems to make my bltouch work.Also I have a breakout expansion board, and I have the yellow cable of the bltouch connected with Heater7 PWM pin on the breakoutboard, and the red cable of the bltouch connected to the 5V+ of the breakout board, and the brown cable of the bltouch connected on the GND of the breakoutboard.
I have the White cable of the Bltouch connected on the Z_probe_in and the black cable of the bltouch connected on GND of the Z probe.
Here is the config file

If somebody has a idea what is wrong or could be wrong please answers.
Thanks in advance

@fireghost2013 When you use the expansion breakout board, it acts similarly to the Duex5 expansion board. That is, the operation of Heater 7 PWM is inverted. So change your M950 line to:
M950 S0 C"!exp.heater7"See this thread for a similar setup (and I still need to add a note to the BoB page): https://forum.duet3d.com/topic/22225/bltouch-not-responding-to-code
