bltouch randomly stops working

kmhudgins

Hi,
So after having the bltouch working for a while it has started to randomly stop working.
i have replaced the whole wiring harness to make sure it was not a wiring issue.
I after shutting my ender down unplugging the bltouch re connecting it. the bltouch will work some times a few prints sometimes not even enough to probe the bed. I was thinking that this could either be the bltouch itself or maby the ports on the duet maestro board. any thoughts?

thank you

Hi Ky,
I had exactly the same issue, that was driving me crazy....
Check the Pin
"Try loosening or tightening the set screw slightly to adjust the trigger sensitivity."
There is a description how to set up the srew, but I can't find it currently.
In the end a quarter turn had reliably solved the problem.

Frank

Edit:
You can find the information in the manual
