Parameters

• Snnn target temperature
• Tn optional tool number

Example

• M104 S190
• M104 S220 T1

The first example sets the active and standby temperature of the current tool to 190^oC and return control to the host immediately (i.e. before that temperature has been reached by the extruder). If no tool is active, it will apply to the lowest non-negative tool number.

The second example sets the active and standby temperatures of tool 1 to 220^oC. If tool 1 is off, it will be set to standby as well (resulting in tool 1 heating up to the temperature given).

See also M109.

This is deprecated because temperatures should be set using the G10/M568 and T commands.
