M871 - Probe temperature config

calibration Configure probe temperature compensation PROBE_TEMP_COMPENSATION

Description

Read/write probe temperature compensation values. Values for bed and/or probe can be calibrated using G76 command.

Notes

Requires PROBE_TEMP_COMPENSATION

Values at index zero are constant (zero).

Compensation values are stored in µm (micrometers).

Use M500 to save the values to EEPROM.

Usage

M871 [B<I|V>] [E<I|V>] [P<I|V>] [R]

Parameters

[B<I|V>]

Write bed temperature value [V] at index [I]

[E<I|V>]

Write extruder temperature value [V] at index [I]

[P<I|V>]

Write probe temperature value [V] at index [I]

[R]

Reset values to factory default (zero)

Example

M871 ; print current values 
M871 R ; reset all values factory default (zero, effectively disabling compensation) 
M871 P I1 V-5 ; set probe compensation value at index 1 to -5µm 
M871 B I2 V20 ; set bed compensation value at index 2 to 20µm 
M871 E I4 V-13 ; set extruder compensation value at index 4 to -13µm
