Hello everybody
At the moment I am building a 3D printer and have bought an E3Dv6 hotend and a Smoothieboard.
I have big problems heating up my hotend to the right temperature. My printer runs completely with 24V.
As a temperature sensor, I have written the sensor type “Semitec” in the firmware, as it is written in the documentation of E3D. As a test I defined the sensor as Epcos100K and could not measure any change in temperature.
According to the sensor, the desired 200 °C is reached. But if I measure with an infrared thermometer, the heat comes to a maximum of 150 ° C - 170 ° C.
The PLA can only be pushed through with a lot of manual force (extruder power is not enough - just clicking).
If the print bed is heated, I get a sensor fluctuation at the hotend sensor (temperature rises without heating up) when heating up the print bed.
I have already tried solutions with E3D and we came to the conclusion that the problem must be either on the Smoothieboard or on the Smoothieware.
E3D said that since it is unusual for the board itself to be defective, there must be problems with the software. They also wrote that the software may not be properly flashed.
I downloaded the latest version of Smoothieware from github and played it on my board following the documentation of Smoothieware, but to no avail.
All components are connected correctly.
Furthermore, it strikes me that when I heat up my hotend the smoothie board emits a very high continuous tone. However, this does not occur when heating the print bed.
Do you have a solution for my problem? Following is the code for my hotend from my Config.txt
# First hotend 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 0.23 # Pin for the thermistor to read temperature_control.hotend.heater_pin 2.5 # Pin that controls the heater, set to nc if a readonly thermistor is being defined temperature_control.hotend.thermistor Semitec # #temperature_control.hotend.beta 4375 # 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.max_temp 300 # Set maximum temperature - Will prevent heating above 300 by default temperature_control.hotend.min_temp 0 # Set minimum temperature - Will prevent heating below if set temperature_control.hotend.readings_per_second 20temperature_control.hotend.p_factor 42.3 # permanently set the PID values after an auto pid
temperature_control.hotend.i_factor 3.197 #
temperature_control.hotend.d_factor 140 #temperature_control.hotend.max_pwm 255 # max pwm, 64 is a good value if driving a 12v resistor with 24v.
Thanks in advance.
Best regards
Steve
