Configuring 10K Water Temp. Sensor

Jordan_Miller41

Hello all,

New to configuring Thermistors and such in the firmware, I have 2 - 10K water temperature sensors that I will be using in my water cooling loop to monitor temperatures.

I have plugged these into temp 0 and 1 for right now to test, and I am getting a reading of 72.3 C or so. My basement is more around 16.5 C, I am sure there is a value to tune, I am just not able to find it in the many forums I have scrolled through. Any help is appreciated!

Thanks in advance.

you need the temperature resistance table for it.

go to https://configtool.reprapfirmware.org/Heaters

click on the beta field and select custom and put in 25 and a mid range and a high range temperature value that is in the range that you will use.

it will generate the T, B and C values you need

If it's a 10K thermistor than you need T10000 in the M308 command (assuming RRF3). The B value you need depends on the thermistor. As the temperature range of interest is low, you can use C0.

Gotcha, I just chose the 10K option in the RRF Config Tool, (which I couldn't figure out before how to get to pop up), and you can see the temperature results below.

Thanks for the help.

@Veti Gotcha, thanks for the tip, I may have to do this for future thermistors.

I'm using one on my watercooled head. Which sensor are you using (got a link)? I can share my config.g if that will help you.

@Nuramori Cool! Of course, here it is: https://www.amazon.com/Barrow-Temperature-Sensor-Fitting-Silver/dp/B06XB4JK7G

I am looking to do an up and downstream sensor to measure the temp split on either side of the radiator.
