M912

Back to the Gcode Dictionary

Parameters

• Pnnn Temperature monitor channel, default 0
• Snnn Value to be added to the temperature reading in degC

Example:

M912 P0 S10.5

Many microcontrollers used to control 3D printers have built-in temperature monitors, but they normally need to be calibrated for temperature reading offset. The S parameter specifies the value that should be added to the raw temperature reading to provide a more accurate result.

(Currently only for the CPU on-chip temperature sensor P0. Other P parameter could in the future be added for boards with multiple on-chip sensors)
