   ### G76 - PINDA probe temperature calibration <a href="https://reprap.org/wiki/G-code#G76:_PINDA_probe_temperature_calibration">G76: PINDA probe temperature calibration</a>
   This G-code is used to calibrate the temperature drift of the PINDA (inductive Sensor).
-  
+
   The PINDAv2 sensor has a built-in thermistor which has the advantage that the calibration can be done once for all materials.
   
   The Original i3 Prusa MK2/s uses PINDAv1 and this calibration improves the temperature drift, but not as good as the PINDAv2.
 
+  superPINDA sensor has internal temperature compensation and no thermistor output. There is no point of doing temperature calibration in such case.
+  If PINDA_THERMISTOR and DETECT_SUPERPINDA is defined during compilation, calibration is skipped with serial message "No PINDA thermistor".
+  This can be caused also if PINDA thermistor connection is broken or PINDA temperature is lower than PINDA_MINTEMP.
+
