However, this thermistor is currently the most sensitive sensor available for very accurate reading at printing temperature, between 180°C and 450°C. At its peak, the resolution goes up to 5.70 increment per degree, or 0.175 degree.
This sensor is far superior than the traditional 100K NTC, PT1000 or even amplified PT100.
However, stainless steel is an alloy containing mostly iron. In almost all cases, when a metal is alloyed, the thermal and electric conductivity are reduced. This means that iron conduct heat a lot better than steel or stainless steel. For your reference, the actual thermal conductivity of iron is about 80 W/m.K, and 16 W/m.K for stainless steel.
As you can see, the thermal properties are pretty different. The same effect happens when alloying titanium, and this is the reason why we have chosen this metal.
Our titanium alloys is a lot less conductive than stainless and allow a much compact and efficient design.
The top part need to keep the filament cold so it can stay strong and hard.
Despite it's small size, the titanium heatbreak is very strong and won't be damaged under normal operation.
You only need to insert the heater cartridge and tighten the thermistor and you are ready to go.
Most hotends use a standard 100 kΩ NTC thermistor which allow them to reach between 235°C and 300°C. The low temperature range enable them to be somewhat accurate at room temperature.
The trade off with a 500°C thermistor is that the accuracy at room temperature have to be compromised for the extra 200°C it can handle. This is due to the ADC (Analog-to-Digital Converter) used in most ATMEL chips that has 10 bits resolution, which means it can differentiate 1024 values.
For safety purpose, we need to modify the firmware to implement a workaround for the low resolution at room temperature. You can find the guide in the support section for our DyzEnd.
A higher temperature allows to use a greater variety of filaments.
The heatblock is designed to be as far as possible from the wind generated by the fan. By positioning it in a different position, there are more heat losses.
We strongly suggest to keep the original orientation for optimal performance.
Changing the pullup resistor can have an interesting effect on readings. in fact, having a lower resistance value will improve resolution at high temperature, but lower it at low temperature.
The opposite is true with a higher resistance value. Readings would be better at low temperature, but worse at higher temperature.
The very common 4.7 kΩ is considered as a standard and yield to a very good compromise between resolution in low temperature and high temperature.
