CR Sprite Extruder Heater Block Kit Extra Thermistors High Temperature Pro 300℃, Ender 3 S1 Hotend Compatible with Ender 3 S1 Pro/Ender 3 S1

I have no idea what the nozzle size is but it’s a great product. Any help on this would be great!

The ceramic hotend is a bit lacking on install instructions but easy to do. Removing the original sprite pro heat break and heater block required loosening one heatsink hex set screw and the two long screws holding the heater block onto the heatsink. I found that the original heat break due to the set screw dimpling didn’t want to pull out of the heatsink. So I just used a thin hex wrench thru the top of the extruder while pushing on the loading tab to push the heat break out. Worked and no damage. I then inserted the new hotend hear break into the heatsink making the bottom of the silo on boot even with the edge of the slanted fan bracket. This put the tip of the nozzle out har enough to have several mm of distance from the fan bracket and bed when printing. Easy enough to readjust if more clearance is wanted. I want as much of the copper heat break in the heatsink as possible. The new ceramic heater is 60 watts vs the normal 40w and does it heat fast. 40 or less seconds from room temperature to 240c and no pid recalibration needed and no thermal runaway triggered. I still did a new pid test anyway. I then set a new z offset and some test prints and DONE.For me it was a easy upgrade and so far great.Being so new I’m hoping to see spare nozzles available soon. Based on my other Creality hotend upgrades, nozzles and thermistors take a while to be available. For now printing pla and petg I should get many months of printing with what I have.I would buy again based on how it’s all working and ease of installing non my sprite pro (sprite also should be).

Fit perfect, and the extra parts are a good bonus.

Great product not a single issue.

Bought this for an Ender 3 s1 and the thermistor had a much smaller plug. Was unable to get it connected. Unfortunately I didn’t find this out until well past the return dateUpdate - seller was able to refund my purchase amount. Investigating whether this is a manufacturing error from the 3d printer or the upgrade kit.

I used this on a custom CR10 and like the faster heatup time it gives. It has worked properly as it should and is a good value.

PRO: This thing heats up really fast. I mean really fast.Con: you can't change nozzle size if that's something you like to try doing.The rubber sock has lost little pieces of itself over the last month or so. It's not an issue if you never have any oopsies, but with 3d printers things happen.Compared to traditional nozzles this one has a larger size footprint sitting close to the board which adds a little challenge when you're trying to peak under there to see how your extrusion is going. This also means if something isn't going right such as adhesion issues where part of the print comes up, there is more hot end to snag onto it. If you have a super level bed and are not having adhesion issues, then this is likely not going to bother youl.

Great part. Easy install
