I just installed a creality V1.1.5 Silent board and a BLTOUCH V3 on my ender 3 I have everything working except when homing the probe hits my finger but continues to go down. I set the firmware up just like Teaching tech did. What changes do i need to make in order for the board to notice when the probe is at the bottom?
If you used th3d TH3D-Unified-U1.R2 and you have bltouch 3.1, try to enable only "// #define BLTOUCH" not "// #define BLTOUCH_V3". I had the same problem.
So with a "BLTouch v3.1" and TH3D_UFW_U1.R2.14 do we need to uncomment or not the BLTouch_V3 line to make it working on the Melzi board ?
Thanks for a confirmation.
AFAIK 3.1 doesn't need it. 3 does need it due to how they messed up the sensor design on those.
