What's the difference between the 300°C Thermistor and the RTD Pt1000?
Both the 300°C Thermistor
and the RTD Pt1000
perform the same task, they measure the temperature of the hot block and relay that to the 3D printer's board. However, there are a few key differences between the two. The 300°C Thermistor
can only read temperatures up to 300°C (sorry, had to state the obvious). The RTD Pt1000
can read temperatures all the way to 500°C which unlocks all of those high-temperature, engineering-grade materials everyone wants to use. It also has a linear resistance vs. temperature curve which just makes sense.
So why would I use the 300°C Thermistor
over the RTD Pt1000
? Well, for a while, the boards and firmware for 3D printers in the past were only capable of reading the values a thermistor provided. So if you have an older printer, it may be possible that it cannot read the values provided by an RTD Pt1000
. However, nowadays it is very common for boards and firmware to know how to read the values an RTD Pt1000
provides. You can even make the RTD Pt1000
more accurate by using an amplifier board like the MAX31865. With all of this said, it is crucial that you reference your 3D printer's documentation to ensure that any temperature sensor you want to use will in fact work with your 3D printer.
How do I update my firmware to be compatible with the Slice Engineering Thermistor?
300°C Thermistor The 300°C Thermistor works natively with Marlin, Duet/RepRapFirmware, and Klipper. Marlin If you are compiling Marlin for use with the 300 °C Thermistor, make sure to choose the "100K thermistor - ATC Semitec 104NT-4-R025H42G". This ...
Updating my Prusa firmware for the Slice Engineering RTD Pt1000
Follow these steps to upgrade the firmware for your Prusa printer for a Slice Engineering RTD Pt1000. This will apply when you plug your RTD PT1000 into a thermistor port with no amplifier board Part 1: Download Prusa Firmware 1. Download Arduino IDE ...
What is the small piece of metal that comes with the temperature sensors used for?
This small piece of metal is a dowel pin. It is used to fill in the extra space in the thermistor slot on the hot block. Since the thermistor is shorter than the slot, the dowel pin is used to fill in this extra space and keep the thermistor in ...
How do I update my firmware to be compatible with the RTD Pt1000?
The RTD Pt1000 works natively with Marlin, Duet/RepRapFirmware (RRF), and Klipper. Marlin When compiling Marlin, choose temperature sensor #1047 if you are not using a MAX31865 amplifier. If you want to print above 300°C, you will need to raise the ...
During setup with my Duet printer, I'm getting a "A heater fault has occurred" error when trying to heat.
Your thermistor resistance/temperature values in the printer's firmware likely needs to be updated. Go to the RepRapFirmware Configuration Tool and follow the prompts until you get to "Heater configuration". Select the EO or E1 sensor channel, ...
