What temp chart would I use for a Semitec 100kOhm NTC Thermistor I use for my hotends? And for a EPCOS thermistor I use for my heated bed?

I think I found my answer for the Semitec. I think I would use Semitec-1004GT-2.cht? Still not sure about the EPCOS one though?

Try and find the product name for the epcos thermistor, you might find it in the folder.

Ok thanks I’ll look up the one that came in the bed heater. Thanks again.

Yes I think perhaps that’s a section we need to expand in the wiki… I’ll write it up as soon as I’ve gotten around to getting my printer moving the right way. (and documented that, as well)

Would you like my Fritzing files as a starting point?

@Elias_Bakken Uh, I’m not sure I know enough to actually work with those… I’ll read the documentation already in redeem first (I think I also saw somewhere a basic guide to create your own .cht file)

There is a tool for it in the “tools” folder, but there is also a pending pull request for beta value system eliminating the lookup tables all together.
