Let me start by saying I bought this knowing there was a chance it wouldn't be compatible with the Ender 3 V2 Neo I intended to install it on, so no star deductions.Being new to the whole Creality 3D printer line up, I wasn't sure what differences the Ender 3, Ender 3 V2, and Ender 3 V2 Neo would have that made them so different. Well through trial and error, I learned a lot.Let me start by saying I love this thing, this comment is not so much on the performance of this but my exploration into learning why this didn't work on my Ender 3 V2 Neo. The Sprite itself is great! Using the base version of the Sprite on an Ender 3 S1 printer now.Before I get started, if anyone is looking for an Ender 3 V2 Neo that uses this Direct Drive Extruder, the Ender 3 S1 uses the base model of the Sprite and the Ender 3 S1 Pro uses this exact Sprite model with High Temp. The entire S1 and S1 Pro printer looks like a modern version of the Ender 3 V2 Neo. It uses some of the same parts too. Either model is great and I currently use both of them. I wish I knew that a little earlier because before I bought the S1 I was trying to essentially convert my V2 Neo to the S1 Pro without knowing. But this kit unfortunately was designed for printers using setups like the Ender 3 and Ender 3 V2, the Neo model changed enough to make this kit, well, useless from the box.The kit offers a back plate to mount your Extruder to the X Axis rail. But on the Neo the limiter switch is place differently to the Ender 3 and V2 versions. This kit has the back plate for those versions. I went as far as to buy the limiter kit for the Ender V2 to adapt my printer for this kit's use. That worked to establish the X Axis limit. Unfortunately the dimensions changed dramatically and the printer could not zero automatically the whole hotend assembly. I had to work with G-Code (since I do not have the means to customize the firmware) to try and adjust the homing of the Extruder. I was able to get away with something close enough. But because I didn't customize the firmware, the auto leveling capability was off the bed and never functioned. Although I managed to manually level the bed it kind of makes the CR Touch pointless beyond homing and offsetting the Z Axis. Couple that with the wrong facing Filament Holder on top and you end up with an awkward setup missing various functions.Despite it all, when I did set the printer to print, it worked wonders, kind of. Hotend heated up quickly without much delay. Extruding was smooth as butter. Until I noticed the major issue that made using this kit entirely useless on my Neo. I haven't found any answers to the problem so if anyone knows why this happens please share. While true that it was operating smoothly it only did so on 1 layer. The initial layer. The system would display the whole gantry would move up but physically it did not. In short, for whatever reason, the system could not send during printing motor commands to the Z Axis motors. When homing or using manual controls the system worked 100%, only during printing did it just... not move, even when the screen said it was several layers higher it would be ironing layer 1 indefinitely. I flashed the firmware to every possible version that would function. But to no avail. I'm sure if I customized the firmware I could have gotten a full functioning system, but that is too much customization for me and the time I have to give to this pet project. So when the opportunity arose I put in a purchase for the S1 and keeping this Extruder Pro kit gives me the best version of the Sprite. With the S1 I have the necessary base that matches my Neo with the added upgrades and the Pro kit to swap it out and get the higher temp functions when I need it. Since both Sprite models have the same external dimensions and use the same Flat Cable? Swapping the units is easy and quick. I have my V2 Neo back to nearly 100% OEM and it prints fine. The images attached shows a Mew that was printed on the Ender 3 V2 Neo just before the S1 arrived. The 2nd image of Mew was take on the bed of the S1 after installation was complete. The last image of a rectangular model being printed is from the Ender 3 S1 with the stock Sprite. That one is printing a Nintendo Switch OLED base wall mount. All of the images display a thermal cover I use with the primary FDM printer. It has RGB LED strips installed which gives it the hue of color.So unless you want to dramatically work out all the little details to make it work. This product does not function with the Ender 3 V2 Neo. But it is a good piece of technology and worth it if it runs on your printer model out of the box. I really wish there were more clear comments and replies on the net about this unit and the Ender 3 V2 Neo.
