* S<temperature> sets the minimum extrude temperature

*
* M302 ; report current cold extrusion state
* M302 P0 ; enable cold extrusion checking
* M302 P1 ; disables cold extrusion checking
* M302 S0 ; always allow extrusion (disables checking)
* M302 S170 ; only allow extrusion above 170
* M302 S170 P1 ; set min extrude temp to 170 but leave disabled
