Nice replacement hot end. My original hot end got one of those jams that just won’t come out without serious heat. I got this one to use while I’m finding time to work on the original. Read more

I bent the original on my Centauri Carbon due to my failure to clear the printing path-- there was a printed part under the bed plate. Read more

I purchased this thermistor to fix a faulty one on my XL Nextruder. It must have occurred during the last nozzle change, but the misreading didn’t start until a couple of days after that. Hah. The photo on this listing is accurate, meaning I received exactly the items pictured. However, the thermistor and heater cables are slightly different from those that come with the XL. I noticed this difference, checked the reviews, and found an XL user who stated that the new module worked for them. They work, and so far, I haven’t had any problems. However, if you’re buying specifically for an XL, you should be aware that the spring-like mechanism at the bottom of the thermistor, where it enters the heat block, will provide significant resistance when installing the new module compared to the OEM module. I assume the spring is there as a protective mechanism to safeguard the connection between the thermistor and the wire. However, it’s intended for an MK4 where the cable can be routed directly into the heat block, unlike the strange cock to the left and slight routing required on the 5th XL version of the Nextruder. This protective spring jams straight up into the fan housing on the XL Nextruder, as it’s slightly modified from the Nextruder on the MK4. As a result, you have to force it into place and hope for the best. I was able to complete the nozzle offset calibration after installation without any problems, so it seems that everything is within spec. However, to get the module seated, I had to bend and press on the thermistor wire much more than I would have liked, considering that the whole point was that I damaged the first one just barely taking it out and putting it back in. Hah. The only thing that could have happened is that it caught on something during removal and was tugged just a tad too hard, because I had no problems beyond a minor catch of the wiring during removal that I didn’t think much of. But somehow, it caused thermistor damage. Now, I’m replacing the damaged thermistor. To do so, I have to manually handle the new thermistor much more than I ever did with the original. It just seemed slightly off to me. But as I mentioned, it works, and there have been no strange readings so far. I passed the offset calibration. I didn’t run a fan or heater check, but I know it’s heating up and cooling down and reading correctly because I’ve already put filament in. Unfortunately, I haven’t printed anything before writing this review. But so far, so good, except for the spring getting in the way of proper seating. Oh! When I heated the nozzle to add filament, it smoked a small amount. Not sure of the cause. Could be the brand new Phaetus nozzle I'm trying, or this brand new heater block/thermistor module, maybe the brand new silicone sock or thirm Read more

I've purchased a couple of these heater blocks for my Prusa MK4S and they work well. The wire connectors are the same as OEM and the performance of the heater and temperature sensor seem equivalent to the original. The wire leads have a little less protection, so be careful when installing / removing. I typically use the Prusa nozzles and not the included ones. The nozzle and throat tube are not tight out of the package, so be sure and tighten them down before use. Recommended! Read more
