I am confused about installing BLTouch on CR-10S.
This is my motherboard:
Below is a screenshot for the wiring of the BLTouch sensor:
See the circled sections in yellow.
Notice that the Z- socket is also used (black and white BLTouch wire) and that's normally where the endstop limit switch sensor is plugged in.
If I unplug the limit switch wire and simply plug the BLTouch wire to this:
1. How can the printer determine when it has reached home?
2. How does it know when to stop when it hits home?
3. I thought BLTouch is used to do some leveling on the surface... Does BLTouch have a sensor to stop the printer when it hits some?
4. Any way to install BLTouch without removing the Z limit switch sensor?
Sorry for the questions. I am just confused about BLTouch using pins of another sensor that's also required.
