WINSINN HT-NTC100K Thermistor Sensor, Ender 3 v2 Upgrade 3x15 3950 XH2.54 2Pin, Compatible with Ender 3 5 Pro CR6 CR10 Series 3D Printer Hotend (Pack of 5Pcs)

great quality, and for the price i couldn’t resist that many.

Overall I was very pleased with these thermistors. They appear to be accurate (well as accurate as the one I replaced) and I like the fact they come with pre-crimped connectors.

First set trigger warnings on my machine, the second set works. I guess this is why it comes with 5 sets.

I questioned whether these worked or not, cutting up 2 already as i thought they were bad, but turns out, i think cura was screwing me up with how the temperatures kept changing, so I had this wild theory that something was bugged in cura from what i was slicing to 3d print. With this in mind, I decided to, as much as i wanted to avoid it, download prusaslicer. I watched a beginner guide and was up and running, I changed the temps to the appropriate tmep for my lw pla. And once I imported my file it said it had ERRORS....FLIPPING ERRORS... There was an exclamation point next to it allowing me to repair, which i did so, and now it has been printing for a couple of hours, no runaway temperatures. SIMPLE FIX: Try different slicers.

If you are looking to purchase this for your 3D printer, specifically the Ender 3 with an upgraded extruder, and have the Marlin firmware installed they will work. I've spent a few hours working and testing them with a multimeter and temperature probe refining the results. Below should get you in the ball park for accurate temperatures on your hot end within 0-1½ degrees Celsius:M301 p32.19 i2.12 d122.30define TEMP_SENSOR_0 6161 is 100kΩ Formbot/Vivedino 350°C Thermistor - beta 3950Using those settings run a M303 PID autotune then use/save the values and you're all set. If you are running the stock Ender 3 firmware, these will not work, you need to have the Marlin firmware installed.

The cartridge appears to be the right size for the E3D hotend but I did not test fit as the connector is not correct for the Prusa board. You clearly see this if you compare the pictures to your existing part. Not sure why there is a review from someone saying they used these on their i3 MK3 as it's a totally different connector.

I wanted to monitor my enclosure temperature inside of Klipper/Mainsail. I just plugged into the th1 socket on my BTT SKR 3 board, added a [temperature_sensor] section in printer.cfg and I had what I wanted. I wish every upgrade to my printer was this easy :)

The heat shrink is crimped into the inside of the cartridge, and is only rated for 125C. The wire insulation is rated at 150C. This is completely unacceptable. If that wasn't insult enough, the end of the barrel is crimped, meaning only about 10mm of the cartridge is round, so it can't be fully inserted into the heater block. Not that I'd use something with such dangerously low temperature ratings, even if it's brominated.

Son buenos en cuanto a calidad de fabricación, pero el vendedor no contesta las preguntas y la información que pone no es suficiente o muy ambigua, para poder modificar bien el firmware por lo que es un dolor poderlos usar, si pueden eviten lo y busque otros que el vendedor si ponga bien la información para poderlo modificar en Marlin

Utmärkt! ++++ :)
