Dear @jeffgar2000
When the printer is turned on, observe whether the BLtouch light is on, whether it blinks, and whether the BL probe will stretch 2-3 times.
Try to reconnect the wire harness of BLtouch
Tighten the top screw of BLtouch and test again
Replace the spare thimble
If the above steps are not effective, consider the BL touch is damaged, replace the BLtouch kit with a new one.
