    Great video, is there any possibility you could show more close-up view/details when moving the wires around the motherboard? I can't see exactly what you're working on and that end of things is fiddly. Thanks.

      Hi Kate, thank you so much for your comment. This is something I am struggling with, firstly as a "one-man-band" I need to do it all and also equipment, ie more cameras, is expensive. I will certainly try to run more b-roll if I can, usually though, that means doing the same job 3 times. The first to make sure I know what I am doing to demonstrate it efficiently, second to record, then a third to record the B-Roll. I will certainly try harder in the future.

    Thanks for your very good video! I want to share with you something I've saw with my Ender 3. I had E1 error in a very erratic way since two weeks ago. I'm pretty new with printers. Looking to this video, to change my thermistor I have found something interesting: I think that the white stuff surrounding the thermistor is thermal grease that becomes similar to melt plastic because high temperatures with time. If you take off the old grease and use new thermal grease it will work very well if the thermistor IS IN GOOD CONDITIONS. With a syringe, the work is quite easy. The reason is that thermistor can vary too much the signal when it has no full thermal contact with the metal block (the variation of the resistence is exponential!). In my case, temp start to jump in erratic ways as the head moves. That's because the movement provokes bad thermal contact.
    Sorry for my very bad english. Cheers from Argentina!

    Hello again. I replaced the motherboard on my Ender 3 3D printer with the Creality V4.2.7 motherboard. The issue now is that the Fans (Thermistor and Motherboard) keep shutting down after I've set the fan Speed to 100% and I have to replace the Thermistor again . Any thoughts? Also, the Settings which is where I set the fan speed isn't taking causing the fan shut down.

  • @Guapogiboy
    @Guapogiboy Год назад +1

    That is interesting. I too updated my firmware when I installed a CR touch and within a few mins of printing my thermal runway error also appeared. Does it mean my previous firmware was unsafely ignoring the thermal runway? Hmmm. Upon closer inspection of the thermistor the wire was poking out of the sheathe where the screw was holding it to the hot end. Also great tip with the cable using the old thermistor to pull the new one thru.

    My old thermistor broke and I went to remove it, it wouldn’t come out. I tried heating it up and then removing it, but the wires snapped and to glass bead is still deep inside the hot end. I don’t know what to do. Should I put the new thermistor in with the old glass bead thing thermistor still in the hot end ?

      Hi George, thank you for your comment. I honestly am not sure what this issue could be, I will post it on my forums and see what reply I get. To me, though, it sounds like it could be a main board issue. A relatively cheap solution is to put in a BTT board and it is a significant upgrade to the original board if you have an Ender 3. I hope this helps

    I ran into a couple issues. The primary one is that there's this heat-proof tape tightly wrapping the wires together where they touch my hotend. In order to get enough slack to replace the thermistor, I'd have to cut this tape, and I don't have anything (or even know what kind it is) to replace it with. The other issue is that I'm working with an ender 3 v2 neo and The plug end of my replacement thermistor doesn't look like yours, so I'm not entirely sure that I'm putting it on correctly. I've looked at lots of other videos showing the replacment for my specific models, but they all show printers where the stock hotend has already been replaced with an upgrade, and the heat-proof tape is gone so I'm back to my first issue. Can anyone help here?

    In most cases the problem is a white powder residue on the thermistor. Just pull it out and clean the white powder off and blow out the hole, then reassemble. It's that easy. This happens a few weeks to few months after getting a new Ender 3. Just depends on how much you use it. Occam's razor, the simplest solution is usually the correct one.

    for anyone who's confused by the motherboard side I'll try to explain it the best I can... so you'll have to flip the printer on it's side to get to the motherboard and there's gonna be two short screws and a long one keeping the bottom plate on, and one more short one on top under the bed. (I'm referring to the bottom of the box that you put the micro sd card in) once you get in there you'll need to tug on old thermistor to figure out which wire it is. (for me it was the furthest one from the hole where the wires come in) mine was hot glued in so I had to carefully cut it out with an xacto knife. simply thread through the new thermistor and plug it into the same spot and you should be good to go... hope this helps
