Identify that thermistor…please!!!
Not even remotely possible from looking at the exterior. Just pick a thermistor table at random and see how it does. Heatbeds don’t need to be particularly accurate.
I don’t know but I’m willing to learn.
Thats oscar!
just a resistor maybe? does it have stripes on it? if so check a resistor ID chart. otherwise I think they are basicly mystery part as soon as they are separated from any documentation from the factory due to the size requirements.
If I were a betting man, I would say it’s one of these: http://e3d-online.com/100k-Ohm-NTC-Axial-Thermistor-Honeywell
But it could be any one of literally thousands of axial glass-bead thermistors that look just like that.
I think we have a winner @Ryan_Carlyle !
Ryan Carlyle is right. There are thousands of them. Can you check the resistance or is totally “broken”? Maybe is something else, not necessarily thermistor?
Check the resistance of it…
@Jim_Stone yea, but the importat thing to know is if you are dealing with snow rebels or desert rebels. (If the recistance increase or decrease with heat)
Indeed. That’s why check the reference…and then do so again when you spike the heat…say by place a mug that has hot water on top of it.
Then you can get what you need.
Or back check thru what you bought lololol
Even if you do measure its resistance @20C, you have no way of knowing e.g. its beta value unless you calibrate it against a know, higher temperature. Trash it, buy a known good one, reconfigure firmware, done.
Btw, my 10ct Aliexpress thermistors look exactly like this one.
@VolksTrieb Damn, you beat me to it…I was going to say Bob…
Thanks for the help folks!
@Thomas_Sanladerer speaking of beta values and thermosistors. i recently received a silicone heat pad (110v 800w) and the only information i get about its thermosistor is this
NTC 100K thermistor ( Beta 25/50 3950K)
i do not know which that would be when talking marlin
