Am I correct to see a lot of blue light emitted by the sensor? That usually indicates that there is something wrong with the cable. Note, having owned about 5 clone sensors, it was a blessing to use the actual product, the clones are underperforming in my experience.

Thank you for your reply! I thought I had wired it correctly, but I will recheck the wires and report back!

# Ender 3 Pro & BLTouch clone issue

(Asked by: username_0 on 2021-01-23)

I just installed a BLTouch clone on my Ender 3 Pro with a standard 1.1.4 board. The sensor seems to work but is giving me problems.
