Our bltouch started randomly stopping mid probe. Sometimes its on the first probe, sometimes later but it never finishes the entire bed anymore. Also sometimes its seems to lag between probe moves occasionally. The probe used work but seems to have slowly gotten worse over time to where now its 50/50 whether the pin will retract or not.

I'm guessing it may be a wiring issues or something with the probe itself? Its fairly large printer with a long run for the cable from the hotend to the mainboard, could interference be a problem?

I have a video of the problem but not enough reputation to posy it yet.

@droftarts Thanks Ian, I will mess with the pin and see if that does anything. I also have a cr touch and knockoff bltouch at home I can test out or swap the pins from.

@droftarts its on old Fusion3 F410. The chamber is not actively heated but the printer is enclosed and we sometimes times run the bed up to 100°C. It doesn't have issues resetting the probe or running the stow, deploy, or self test commands. I will check the wiring connections today.
