Hello Smoothieware:
     I have a problem :  heating hotend temperature is very very slow, 30℃ to 200℃ need around 5mins. if heating to 240 need more than 15mins.   it's very slow. my other 3D printer (mariln firmware) heating speed is very fast. around 30℃ - 200℃ need around 2mins is enough. 
     Kindly if I open the cooling fans. the hotend temperature will very easy and fast to going down. 

     I don't know how to change the config. Could you help me ?

thanks 

following is my temperature config list :

# Hotend temperature control configuration
temperature_control.hotend.enable            true             # Whether to activate this ( "hotend" ) module at all.
                                                              # All configuration is ignored if false.
temperature_control.hotend.thermistor_pin    0.24             # Pin for the thermistor to read
temperature_control.hotend.heater_pin        2.7              # Pin that controls the heater, set to nc if a readonly thermistor is being defined   2.7
temperature_control.hotend.thermistor        RRRF100K       # see http://smoothieware.org/temperaturecontrol#toc5
#temperature_control.hotend.beta             3960             # or set the beta value
temperature_control.hotend.set_m_code        104              #
temperature_control.hotend.set_and_wait_m_code 109            #
temperature_control.hotend.designator        T                #

#temperature_control.hotend.p_factor         96.6             # permanently set the PID values after an auto pid
#temperature_control.hotend.i_factor         7.759            #
#temperature_control.hotend.d_factor          301              #

#temperature_control.hotend.max_pwm          255               # max pwm, 64 is a good value if driving a 12v resistor with 24v.

about the P.I.D vol I already changed. before the volume is P:13.7  I:0.097   D:24   but it's still not working when I changed to the above volume.   
So I don't know where to change the config.  please tell me.
 

thank you very much.

Are you using a 24V heater with a 12V power supply?

What smoothieboard do you have? if it is a clone then they have bad mosfets and no mosfet drivers.

Did you run an autopid M303? it is all documented here...  http://smoothieware.org/3d-printer-guide#toc11

NO,  12v heater with 12V power.

Yes, I has run autopid M303 E0 S190, I was doing exactly as this documented. and also I change PID to the new RESULT. But still heating slow. nothing changed.  
Please tell me my config is correct ? like the beta 3960 ? MAX PWM255 ?
you know my hardware is no problem. when I change to MEGA2560+RAMPS1.4 the heater is fast to heating. just use the smoothieBoard is heating slow. so I m not sure the config have problem or not ?
thanks

before the P.I.D. is P:13.7  I:0.097   D:24

Your PID factors are commnented out so they are being ignored by Smoothie.
