PINDA or other 8mm sensor is much smaller and lighter than 12mm sensors, but they are just as useful. P.I.N.D.A. is an DC 5V NPN NC inductive proximity sensor.

If you do not use the built-in temperature sensor, you will need to wait a few minutes between each print to cool.

The latest version of Marlin finally includes P.I.N.D.A. probe temperature compensation: https://github.com/MarlinFirmware/Marlin/releases/tag/2.0.2

Temperature calibration: https://marlinfw.org/docs/gcode/G076.html

Marlin config:

#define TEMP_SENSOR_PROBE 1

#define TEMP_PROBE_PIN 15 //TEMP_1_PIN

#define FIX_MOUNTED_PROBE

#define NOZZLE_TO_PROBE_OFFSET { 28, 12, -0.5 }

#define MIN_PROBE_EDGE 30

#define Z_CLEARANCE_DEPLOY_PROBE 0
#define Z_CLEARANCE_BETWEEN_PROBES 1
#define Z_CLEARANCE_MULTI_PROBE 1

#define AUTO_BED_LEVELING_BILINEAR

Wiring:

• blue: GND
• brown: +5V
• black: signal
• white: thermistor

GND, +5V, Signal -> Z min endstop
PINDA thermistor -> second HotEnd thermistor
