Wiring:
The BLTouch can operate under the following conditions: One control I/O (Orange wire for PWM or Software PWM), one I/O for Zmin (White wire for endstop / Z-probe) and GND and +5V power. Most boards have their own servo pins, simply connect the BLTouch to one of those. The servo pin number is used to control the BLTouch as follows:
M280 P0 S90 ← SERVO0_PIN
M280 P1 S90 ← SERVO1_PIN
M280 P2 S90 ← SERVO2_PIN
For example, a RAMPS1.4 Wiring configuration would look like this:
Servo signal (orange wire) – D11 (SERVO0),
Zmin (white wire) – D18 (Zmin endstop)
The package includes the following items:
- BLTouch Auto Bed Leveling Sensor
