High Temperature Plated Copper Heater Block Compatible with Anycubic Vyper Sidewinder X1 X2 FLSUN SR Volcano Hotend PT100 Cartridge Sensor DDB Extruder 3D Printer (Copper)

Perfect fit

I saw another user comment that this part did not work with their Super Racer and just wanted to add my experience that this did work great for me with mine. I did also add a bimetal heat break, which as far as I understand things helps with the thermal runaway issue that person ran into.For Super Racer owners looking for an amazing upgrade - this block + silicone sock + bimetal heat break + a higher quality brass nozzle is a massive improvement especially for speed and larger nozzle sizes than .4mm.

Though it's a TIGHT fit in my "Flsun Super Racer", I have a feeling this fits perfectly on all machines it was intended for.If you change nozzles regularly it may wear down fairly fast, but in the last year I'm only on my second one, and the first wasn't even THAT badly worn.I had to replace my Flsun's original block because it was crooked straight from the factory, and again, while this is a little tight in the machine, it DOES work

The plating is excellent and the machining tolerances are spot on, it's just a hair large for the silicone sock that came on the original heat block. The only issue I had was a small burr where the grub screw holds the thermistor cartridge, I had to twiddle a screwdriver in the hole before the cartridge thermistor would fit. Keep in mind that is adds some additional mass to the extruder so you may have to adjust accel & jerk settings. Be sure to do a PID tune & flow calibration.

Ordered 2 of these at the same time. I machine away the extra mass to reduce startup times. First one was copper. Second one was brass, maybe bronze. Brass alloys are usually about 1/3 the thermal conductivity of copper and not good for this application. Since I had already milled away a chunk and probably couldn't return I went ahead and finished and installed- did not work well.

Es un bloque pesado y macizo! A diferencia del original que se notaba de mala calidad, estoy satisfecho y lo recomiendo (se lo instale a una Anycubic Kobra Max)

I ordered these back in early 2023 when they had a sale as I needed to stock up on spare parts for my FLSUN Super Racer. They were advertised as being compatible with my printer and appeared to be of great quality when they arrived. Unfortunately, when I went to go use them, they were anything but that - The ones I received are not compatible with the FLSUN thermistor at all, as you can see in the second photo with the single screw in the side. I have a bunch of extra Creality thermistors on hand, but it won't even take those, either.Bottom line about this product: Quality is pretty good, but quality control post-manufacturing has a lot to learn.

Fit and finish were good, attached to my printer without issue, and after some PID tuning, my hotend temp is noticeably more stable than with an aluminum block. It is a bit heavier than aluminum, but I’ll deal with the added weight for consistent temps.
