Hello, I recently installed a BLTouch 3.1 on my CR 10 controlled with a Duet 3 6HC. I have double checked the wiring harness, and 5 volts is being pushed all the way to the end, right where the BLTouch connects. I have tried configurations for IO Pin 7, and IO Pin 5, but to no avail. Because this is a first install, I do not have any previous data of the sensor working, or not.
When the probe is unplugged from the wire, the z-probe out on the dashboard for DWC indicates 1000. When it is plugged in, the reading is 0.
I have tried manual "M280 P0 S10" and "M280 P0 S90" commands, but there was no change. I think I am missing something.
Here is a copy of my config.g:
