st Robotics] HEX EPCOS Thermistor Upgrade for Creality Ender 3 Ender 5 CR10 3D Printers (1.5M 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.

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 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.

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 have had this Thermistor for several months now. Since installing it, I have to baby sit the print for the first 20 minutes. It will continually jump up and down on temp and will not start even after flashing the board and doing several PID tunes. I think this company means well and probably has a decent product sometimes, but for me the QC failed. Its been to long for me to return and I don't want to bug the company since it doesn't fit right in an ender 5. I swapped it to my ender 3 for a month to make sure it wasn't just one printer and it was in fact the thermistor.

Easy to install, holds Temps wonderful, good quality, hard to become unplugged

HEX EPCOS Thermistor Upgrade - Best Thermistor upgrade for my Ender 5 Plus.. Awesome shipping..!! Thank you..!!

Only issue I had that is really minor is the silicone sleeve it comes with is too big . The fan cover wouldn’t go back over the hot end . Took the silicone piece off , cut about 30-40% off put it back on then wrapped the wires in heat resistant tape.If anything changes down the line I’ll update review . Installed on december 31st 2021Update January 24 2022 : now I keep getting thermal runaway on my printer anywhere from 2-12 hours into a print . I will go through and check everything and if nothing changes I will go back to the old thermistor and see if that solves the problem ….Update March 2nd … the company actually saw my review and sent me a replacement for free , they said they tried contacting Me but I have no way of knowing where I would check for a message . Regardless them sending me a replacement without me reaching out to them , says a lot . Sometime down the road I’ll try the replacement part but printer works fine with regular thermistor now and going to enjoy it before taking it apart again
