So Unsure how many people saw my post last week about a bad thermistor on an e3d hot end. After a little research, I opted for a drop in type model you can find on Amazon.
This is a video review I did of it soup to nuts. Kind of considered myself a guinea pig, since it didn’t have many reviews.

The screw-in thermistor is widely available on eBay individually. When I upgraded to the e3dV6 in 2014, I never installed that wonky stock thermistor - I went with the screw-in type from day one. I’ve never had a problem, never lost a thermistor, and my hotend has been disassembled many, many times. There are arguments for and against both types; but, I’ve never had problem one. This is definitely a good upgrade to the e3dV6.

I’ve went thru 5 of these
The glue they use is not all that great a little bit of
Pull will result in the thermistor coming out. Some may be better than others.

@Glenn_West To that point, I saw another video where Zennmaster used Thermal Exhaust paste to seal them in a heater block. When I told one of my car guy buddies about this, he asked me how he ever got them back out, since it’s like high temp JB Weld? If I can source the hardware, I might make up a few thermistors like this, but rather than high temp epoxy, use this stuff.
Here’s the vid I’m referring to https://www.youtube.com/watch?v=Y3CffV7VkOQ

@Mike_Learned ​, it’s like a very porous form of concrete when dried. You can pick it out with a dental tool pretty easy.

@ThantiK So, High temp epoxy would be a better route?

@Mike_Learned I had a high temp epoxy thermistor in my J-Head MKIV B for close to 4 years without anything ever going wrong with it. So I’d say yeah.

So, apparently, I should just hold off until something goes wrong. Considering the description for this thermistor says it uses High Temp epoxy.

I’ve ordered some lug thermistors from the us.
There a branded one.
What is the screw length for e3d?

Thanks great video. Need to look at my E3Dv6 and see the condition of my Thermistor. Need to order one or two of these kits.

@Glenn_West According to the E3D wiki, the clamping screw length is M3x3.

@Vaughan_Lundin Thanks, sir. I had to replace mine due to physical damage, but if you have a way of taking the thermistor out of circuit easily and measure the resistance at room temperature, it should be right around 100 K ohms. Only two reasons I could see replacing it was physical damage or failure.
