M106 - Set Fan Speed
Usage
M106 [P<index>] [S<speed>] [T<secondary>]
Description
Turns on selected fan and set its speed. By default, if no fan index is given, the nozzle cooling fan is selected.
This command is applied to the next block of commands added to the execution planner. It means that during printing it will take effect after previous moves in the planner are done. So it will be delayed a bit. When printer is in idle under manual control M106 will execute and change the fan speed immediately.
