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 the 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<flag>] [E<flag>] [I<flag>] [P<flag>] [R<flag>] [V<µm>]

Parameters

`[B<flag>]`	Store the value `V` as the Z adjustment at index `I` for the Bed.
`[E<flag>]`	Store the value `V` as the Z adjustment at index `I` for the Extruder.
`[I<flag>]`	Index at which to store the given Z adjustment value.
`[P<flag>]`	Store the value `V` as the Z adjustment at index `I` for the Probe.
`[R<flag>]`	Reset all Z adjustment values to factory defaults (zero).
`[V<µm>]`	Z adjustment value, in micrometers.

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
