Welcome to the SeeMeCNC Community

Is it true i can use any 100k thermistor? if so, why not use the GP104L8F from DigiKey? it allows us to go to 300C instead of the stock 200C. it looks to be quite a bit smaller than the B57540G0104F000. am i looking at this right?

all help is appreciated.

See this before using any thermistor. https://www.youtube.com/watch?v=dU2S1heu3XU

You can use any thermistor, but you'll have to adjust the firmware to get an accurate temperature reading.
The really small ones are a pig to work with.

Just get a thermocouple and call it a day. You'll never break the leads, it's more accurate, and it'll go up to 1000C+

So, if you decided you wanted to, you could crank up your hot end, melt the brass and aluminum, and accurately report the temperature throughout the whole process

This is actually the route i wanted to take, i've just never read a thread where anyone was actually successful in setting this up. If there is one out there that you know of, it would be really excited to read it.

Thank you for the help!

I haven't used a thermocouple, but the pt100 shares the advantages, and is pretty simple to set up

It's straightforward with that board.

You change the Heat_0_pin in pins.h, and you change the thermistor type.

I'm on repetier .92.3, and I've modified a fair amount of it, otherwise I'd just send you mine.

If you attach your config.h and pins.h files, we can help you with the firmware changes
