[Gulfcoast Robotics] HEX EPCOS Thermistor Upgrade for Creality Ender 3 Ender 5 CR10 3D Printers 1 Meter Extension Cable

I do not know why I did not upgrade to this earlier. Install once and forget about it because you will not have to worry about cheap wires breaking like the standard Creality bulb. I installed this in place of the bulb because of a time rush and I could not get the OEM bulb within a day like this hex thermistor. I am glad I did. It is installed into a Micro Swiss All-Metal Hotend for the CR10s Pro V2. The fit is nice. After doing a PID Autotune, this thing just works. It has not had any thermal run-off or issues keeping temp. There are only two caveats. Depending on which way your heater block is facing, there can be issues where the silicone sock for the hex screw pushes against the hotend fan housing causing a tight fit. I left the sock off with no issues so far. The second one is that the plug in for the mother board does not have the lip clip that a standard Creality thermistor has. I had to jam the cord in, but it is working. You could always splice the Creality connector, if needed. Overall, get it and forget the worries of breaking another fragile bulb with a screw.

This should be the standard way to implement thermistors in 3D Printers. One doesn’t necessarily need to change the thermistor if it hasn’t suffered a dire problem but functionality/performance-wise, this is at least OEM-level if not better in accuracy. The difference is this design is miles ahead in reliability and quality. It is by far more secure and strong than the typical industry-standard which simply tucks in an ancient resistor into the heat block. The cables are much stronger and sturdy and the hot-swappable design means you don’t have to redo your whole wiring set-up if you somehow manage to break this strong and sturdy, top-notch thermistor.

I kept having issues with "thermal run-a-way" on my Ender 3 pro. I heard about this upgrade and decided to give it a try. WOW! Am I pleased. I replaced the stock thermistor with this one about 6-8 months ago and have not had any more problems with "thermal run-a-way".

I took a chance on the purchase for my Ender 3V2. It is compatible with stock hot-end, replaces the screw used to help secure the glass bead thermistor in the block--I confirmed this. However, it is not compatible with the Dragonfly BMS. I was hoping to be able to screw in the thermistor but the slot on the dragonfly heater block is a slight bit larger (roughly 3 mm) so the threads do not catch.Can't fault the listing, I'm sure the thermistor is fine.

I installed this on a ender 3 pro and after ran a PID tune to adjust my printer. I ran a few good parts and then the temperature started to vary from 192-208 did another pid tune, ran good for one part and then varied again

I have been having a lot of thermistor issues, so when I installed this one it was really nice to know it wasn't well, fragile as glass. My only complaint is that the rubber insulatior sticks out just enough to impede the fan enclosure on on the hotend.

No more worries about the thermistor falling out or cutting the leads trying to get it stuck in place. This thing is magical.Updated:When this first arrived, I was using the stock Ender 3 fan shroud, which I was able to bend a little, which angled the parts cooling fan a little. It worked, and was amazing.I printed a FANG fan shroud to upgrade the parts cooling to 20mm straight instead of blower. This nut is no longer 'too long', so nothing is bent and it's super clean.TL;DR: this is best if you aren't using the stock fan shroud.

I ordered this to replace the Thermistor on my ender 3. Once I received it, I found it very easy to replace by just screwing the thermistor in place. The thermistor also comes in two parts, the first one is the connection that connects the thermistor to the Processor Board. The second one is the thermistor itself that has a quick connection to the cable. This allows for easy replacement in the future if I need to replace it again.
