BLTouch sensor not working
-
Hi Everyone,
I'm having a very strange problem and I have no idea What's causing it or why this has suddenly Popped up. I have a Duet mini5+ hooked up to 2 1xd's and 1 toolboard 1lc. I have a BlTouch hooked up to the Toolboard through the io0 port and I've had almost no issues until now. When I give the command to touch off Z it doesn't deploy the probe. I have rewired the sensor thinking that was the issue but nothing changed. At which point I broke out my oscilloscope to see if it was even generating a PWM signal to deploy the probe at which point I discovered its no longer generating any PWM signal. I updated the firmware with zero change and I'm not sure what to do at this point. I have attached my config file as well as my M122.
Thanks for all the help in advance

Can you test the BLTouch directly connected to the Duet? Reconfiguring the servo pin, etc.
