Well I feel defeated. Anyone successfully get a BLtouch working with the Azteeg X5 Mini V3? My issue is when G28 Z is activated with pin down the Z axis doesn’t stop moving when pin is lifted and has caused at least 3 crashes. The pin appears to lift and drop repeatedly during contact.
I have since started doing testing MUCH further away from the head and manually trigger the BLtouch, but still no luck.
Any successful configs out there? I added mine below.
