:boom: FlashForge printer FAN speed control firmware fix ( allow to use M106 fan control GCode )

FlashForge

The following GCode commands have been updated:

• M106 [P<index>] [S<speed>]
• M107 [P<index>]

P - fan index, 0 - cooling fan (used also if parameter was omitted), 1 - rear case fan
S - speed, from 0 to 255. S255 provides 100% duty cycle, S128 produces 50% and etc
Examples:
M107 P1 - disable rear case fan ( equal to M107 P1 S0 )
M106 S128 - set cooling fan to 50% duty cycle ( equal to M106 P0 S128 )
M106 P1 S200 - for rear case fan, speed is nominal value, it can be only ON/OFF state

GCode controlled temperature limits was raised up to 280°C ( bed and hotend ). GUI menu limits stay same. Make sure what know what you doing with this.
