Thermistor Temp Table - Marlin - How To - Chris's Basement

- Опубликовано: 16 июл 2024
- NOTE!!! Slice Engineering doesn't offer the bead type thermistor. This was a one off, the cartridge type they sell works the same way.
We setup a thermistor in Marlin from a vendor temp table. We use the Slice Engineering thermistor for this one.

You go over a lot of subjects that not a lot of people think about until they're scrambling through Google searches looking for answers.
I see your channel as an encyclopedia for 3d printing. Great work once again!
Thanks Justin! Those are very kind words, much appreciated.
@@ChrisRiley Quite welcome!
Looked like a Filament Friday Tool Kit brush made a cameo at the end!
I didn’t know the thermistor tables were there.Thanks for sharing that.
LOL, yes it did! I have been using the crap out of those tools.
Thank you for sharing Chris, great info. For those having trouble getting the fiberglass sleeve for the thermistor, you can hijack it from old or unused heat cartridge wires. Given heater cartridges are less than $1 each It's probably cheaper than purchasing it separately.
Thanks! Good call, I didn't think of that.
Awesome video once again Chris. I love the attention to detail that you put into them. You keep them short but leave nothing out. Top class fella
Thanks Andy!
Always clear and no confusion. Great video Chris.
Thank you!
Super detailed Chris, thanks and great job!
Thanks Ali!
Glad you always cover the hot topics.
I'm all over it.
Great job Chris, as always. Thanks!
Thanks Ron!
A Craftsman multimeter....wow - didn't know they existed! Excellent video Chris, will help with some of the off-brand thermistors I occasionally come across.
Thanks! Yep, this one has some mileage on it. :)
Great tutorial, thanks Chris. Trying to build an extruder/hotend for the MPCNC so this will come in handy. Thanks as always for sharing.
Thanks! Hope it's helpful.
Man! you are good! this is what I call a good tutorial. Excellent work.
Thanks!
Great tutorial and info Chris, thanks for the Notepad++ tips too, that will save me a ton of time in the future. Yep, I've been doing it the hard way :-)
Spooky that you released this now, my Micro Swiss hotend (CR-10S) sprung a leak today, looks like the nozzle has come loose, plan to have it apart tomorrow. The spooky thing about that is, I was trying to print the Petsfang duct and mount for it. Now printing it on the faithful Prusa MK2.
Good old trusty Prusa! ;)
this was the one to make me subscribe. Great video, I was deepdiving after getting a weird aliexpress thermistor, and thought itd be easier to clone my own temptable. I was stumbling through it, and you covered all the bases. Wish I found this video first. Great stuff dude.
Thanks for the sub!
Great video as always. This is one project I dont think I will have to do, but it is good information just in case.
Thanks John!
Hi Chris I would give you the (nobel prize) I searched all over the web and no one who explained me how to set up these tebelle in Marlin (Skynet) firmware Fanstastic ...thank you very much
Happy to help! Thanks for watching
Good bit of info! Well done.
Thanks!
Awesome video, Chris! I suspected my Ender 3 + SKR Mini e3 (v1.2) had its temperature readings off... (I could only get good ABS prints at "260C") And indeed: 240C was actually 220C - measured with a multimeter's thermistor. I don't know if the problem is the actual thermistor OR something on the SKR Mini board AD converters... But I'll make a custom table as you've shown. Thanks man!
Thanks for watching! Yeah, I question the accuracy of a lot of these thermistors, like you have found, it really only becomes a problem when you try some of the high temp plastics. Good luck on the calibration.
Wow that is nice
Thanks Paul!
I will try that, Thanks Chris :)
You're welcome!
Great video, looking forward to your "How to add to Duet" version of this video..
Thanks Karl! Yeah, that might be tricky.
@@ChrisRiley I have faith in you... ;)
Ha ha ha! Thanks!
Nice, thanks for sharing :-)
Thanks!
Just looked now, and the Slice Engineering thermistor and its table are part of the firmware as number 67!
LOL, nice! Hope I was the cause of that.
@@ChrisRiley Ha ha, it most likely is the case actually!
Super .. :)
Thanks!
Hey Chris thanks for the video. I do have a question, I am trying to set up Marlin 2.0 in Arduino but I don't see the thermistor.h in there, did they move the location of where you can input this table?
*Update - I found the thermistor.h file in ../src/module/thermistor. They already have the 67 file in there, so I am just guessing now all we have to do is edit the configuration.h file correct?
That is correct, now you can just use the 67.
Thinking of getting this thermistor, but curious if it's the same as the much cheaper E3D high temo/precision terminstor (PT1000)
They are pretty close to the same thing all in all.
I have a PT1000 temp sensor now, but the table of this sensor (type 1047) does look nothing like the table of a thermistor, how do I calibrate a PT1000 !? Can't find anything on the net..
Things have changes a lot since this video. It depends a lot on if you would need an amplifier for it or not.
@@ChrisRiley In my case, I have a (ampless) PT1000, connected just the way you would connect a regular themistor.
I would be interessted to see how to etup a calibration table in Marlin for it. I can't find any info anywhere..
@@winandd8649 Same here..
Like this video, However, I am unable to find the Thermistor RT Table for the 300c, is there a reason this isn't found?
300c? Which heater/thermistor is that?
@@ChrisRiley sorry, its the bondtech one, i added it as max temp 285 in marlin, and used the set value 5 from the configuration.H file as per their recommendations
is there any place i can go to that can make a thermistor table for me as i am having a very hard time reading the thermistor datasheet
Not that I know of, you would have to build one with a probe or find someone that has already built it.
@@ChrisRiley i found a data sheet for my thermistor and i think i made the temp table for the firmware correctly but not sure the only way to find out would be for me to test it would be to use it
why is the adc_count 1023, and not 1024?
that's 2^10-1, which i understand that represents the maximum value of a 10 bit unsigned integer.
But that adc has in total 2^10 return values, because the first one is 0, not 1.
You already know a ton more than me about it. lol I was just going by the table I was given.
@@ChrisRiley please don't take my question as any form of critisism, i'm just trying to 'harvest' the audience of this channel on a loosely connected issue, which i haven't been able to understand for a time 😃 keep up good work, i like your videos very much 😃
@@speedseeder Not at all, comments are always welcome.
First!
You win!
Hi Chris, thanks for the Notepad++ tricks and whole video! Trying to upgrade my printer with PT100 and amplifier board but as only update Marlin firmware, got Max Err E1. Any idea? Settings are according to wiki.e3d-online.com/E3D_PT100_Amplifier_Documentation. No doubt in wiring and so on. At room temperature voltage from Ampl. board according to calibration table. 1.20-1.22v
Well this is the first time I have ever seem this config. I am not even sure how it works. Sorry I am not much help here.
hey Chris, this is Chris 🙈
awesome video as always, thanks for sharing your findings. did a little searching through `thermistornames.h` header file and noticed that the slice engineering 450ºC thermistor table has been added to marlin 2.0 bugfix branch as of ~ march 2019. funny enough it's thermistor 67, looks like your video may have rubbed off on some people. below is the PR where the 450ºC thermistor from slice engineering was merged into marlin.

cheers 🍻
Chris
Hey Chris, yep, that 67 might have been on purpose. ;)
@RedOps RGB Wow, that's not good.
