This process can take a very long time. The timeout is currently set to 15min to allow the parts to fully heat up and cool down. Use [`M500`](/docs/gcode/M500.html) to save the result to EEPROM.	tag optional description B true Calibrate bed only tag optional description P true Calibrate probe only	code G76 ; calibrate bed, then probe G76 B ; calibrate bed only G76 P ; calibrate probe only

Calibrate temperature compensation offsets for bed and/or probe temperatures. Temperature compensation values are added to probe measurements when running G29 mesh bed leveling. Currently, calibration only heats up the bed, not the hotend. The probe is heated up by bringing it close to the heated bed and cooled down by moving it away.

See Probe Temperature Compensation for a more detailed explanation of the process.
