Usage

M301 [C<value>] [D<value>] [E<index>] [I<value>] [L<value>] [P<value>]

Argument Description
[C<value>]

C term (requires PID_EXTRUSION_SCALING)

[D<value>]

Derivative value

[E<index>]

Extruder index to set. Default 0.

[I<value>]

Integral value

[L<value>]

Extrusion scaling queue length (requires PID_EXTRUSION_SCALING)

[P<value>]

Proportional value

Notes

Requires PIDTEMP.

View current PID values with M503.

If EEPROM_SETTINGS is enabled, all hotend PID values are saved with M500, loaded with M501, and reset with M502.
