How should I check the temperature setting of the extruder


Recommended Posts

In the 3D printing process, the temperature setting of the extruder plays a crucial role in the print quality and the performance of the final product. The correct temperature setting ensures optimal material fluidity, adhesion, and bond strength between layers. Here is my summary of a series of steps and considerations on how to check the temperature Settings of 3D printer extruders.
First, you need to ensure that the 3D printer firmware is correctly configured. Marlin Firmware is a widely used open source 3D printer firmware that makes it easy to set and control the temperature of the extruder. After downloading the Marlin firmware to the control board (such as Mega2560), you can use software such as Printrun to connect and control the printer.
Secondly, the function of the extruder heating rod is checked by the Printrun software. Select the correct serial port number and baud rate in the software, after connecting the control board, select the "Heat" option and set the target temperature (such as 185 degrees for PLA filament or 230 degrees for ABS filament). Observe whether the current temperature of the heating rod (Ex0) gradually rises to the Target temperature (Ex0 target). If the temperature curve does not rise, check whether the connection between the heating rod and the temperature sensor (NTC) is normal, and measure its resistance with a multimeter if necessary.
In the temperature setting process, it is necessary to fine-tune according to the actual type of material used and the reference temperature provided by the supplier. For example, if you are printing with a new material, you can start with the recommended temperature and then gradually adjust it according to the printing effect. Usually, if the temperature is too high, the material drawing phenomenon will occur, and the temperature should be gradually reduced (such as reducing 5 degrees each time); On the contrary, if the temperature is too low, it may lead to poor lamination or insufficient strength of the print, and it is necessary to gradually increase the temperature.
Finally, it is recommended to use professional temperature monitoring equipment, such as the FOTRIC thermal camera, to monitor the temperature of the extruder and nozzle in real time. This device can provide accurate temperature distribution information to help users adjust temperature Settings more accurately, improve print quality and product performance.
Through the above steps, the extruder temperature Settings of the 3D printer can be effectively checked and adjusted to ensure the smooth progress of the printing process and the quality of the final product.
