Hi, we have been having some people ask us how to use the 500C thermistor from their Pico with Smoothie. If there is any info you can help share, I would love to work with you to share the solution with everyone.
Thanks

Do you mean you want to use a thermocouple ?
It is actually a 500C capable 2.705 kOhm thermistor and not thermocouple. Its nice to use a plug and play thermistor without having to buy extra components for a thermocouple. We have a temperature table for it and would like to know how to implement it into Smoothie. Thanks
Hi !
Do you have the “beta” value for that thermistor ? All you need to do is tell that and the resistance to Smoothie and it will do the math itself, no need for a table.

Thank you for the help. I am personally not using Smoothie but want to help others who are using it. I do have the Beta value though: B 150/250= 5300K +\- 3%
This thermistor’s B value is provided at 250C instead of the typical 100C. If you are able to try this out and successfully get it to work, please let me know and would happily pass on your results. And again thank you for the help.

Mike are you looking where in the code switch thermistors, don’t know know where a thermocouple came from.
I will need a answer also. I know for Marlin there is a config.h where one sets the thermistor.
