My new HP copier died. This machine did not. This elegoo printer is the best affordable and high quality intro to 3D printing. The parts provided, tools, and starter filament are all fantastic. I am another one to say that it did work straight out of the box and producing high-quality prints though results may vary. Because of the nature of the printing experience, it’s very important to understand fundamentals of how the machine works, and make sure certain things are adjusted properly and certain things are tightened. Regular maintenance of the machine would be recommend. I’ll begin now with faults here which are related to the setup. The setup of the machine and use is not fully detailed in the manual. There are several things to pay attention to, that’s not in the manual. For instance, they don’t tell you that the build plate is magnetized onto the machine and you remove it after a print and the bed cools, then you flex the plate to get your print job off. Took me a good moment to find this out. Other things left out are related to setup and maintenance. Do research on the machine before you get it, and you’re certainly more likely to have a good printing experience. It also does have a couple software faults maybe to keep aware of. I had a print job fail to resume after pressing pausing it. And I’m not sure if it had anything to do with how my model gcode was written by the slicer. Also keep aware, be sure to remove your model after a print. Further actions you might take after you return to the home screen are not aware of whether any material is still on the build plate. So if you’re not careful, you could run the print head into your build and destroy things including the printer. Furthermore, the machine is not WiFi connected and I thought it was supposed to be. I’ll have to check on that later, however it still does have an Ethernet jack. Now onto print fails. Running the printer at high speed is nice, but it can introduce problems in both the machine and prints. Be sure to upgrade the machine maybe if you want super high speed like advertised and use a high speed filament. The servo motors can do it though. My other fail is possibly from a bad slice from Cura slicer. Cura provided a warning about the STL I was printing, so I’m assuming that the print issue there was not related to the printer itself. Lastly, the auto bed leveling is working well. It took time because some of it is still manual. Again, experience may vary and do your research. Overall, as a first time user, I’m extremely satisfied because I’m a user that understands nothing is perfect and overall, elegoo has put out a noteworthy milestone in 3D printing. I’ve also attached a photo of my 3D benchy for reference of print quality

The media could not be loaded. This is my 2nd 3D printer (my first was a Robo 3D R1+) which got me interested in the hobby but although the company advertised that it could print a dozen different types of filament it only successfully printed PLA and Carbon Fiber (but not strong prints), but this Elegoo Neptune 4 Pro is amazing! The thing was packaged well, easy to assemble, and needed only a minor adjustment in the Z axis before printing everything I throw at it so far. TPU, PLA, ABS, and now Nylon. All prints are coming out perfect and they are very easy to remove from the build plate. The customer support team is outstanding as well, I had a few questions about the firmware update and they responded within a day (they are 13 hours ahead of me). Picture and video is it printing a paper towel rack for the garage, slight stringing but the finished product is flawless. 👍 Update less than 2 years later: started having problems with the filament jamming up the extruder and their support suggested updating the firmware so I did that and the printer quit working completely. So they replaced the whole printer, then the extruder assembly and external cables were a problem so they replaced them. I have not had good luck with my Elegoo Neptune 4 Pro so during the 2 years that I have had this printer I have been able to print successfully for a couple months so I will NOT be purchasing another Elegoo product and reviews will be very unfavorable. Their technical support team is outstanding but their product is terrible.

The media could not be loaded. I bought this believing I was buying a good product, that Elegoo stood behind their product. I used my neptune 4 pro for about a month and a half with no problem. I loved how quick the prints were, and the quality was great. I bought the three-year warranty in case I ran into problems. One day my print failed but only at the last part of the print. It started knocking the supports off and making a mess. I haven't been able to get a good print since. I contacted the warranty company, and they sent me back to Elegoo. I have been working with them for about a month, trying everything they asked to no avail. I think I have re leveled the print bed 50 times. The prints work for a few layers, and then it starts acting rough. I have wasted more than a spool of filament through his process. I have tried PLA and PETG to see if that had anything to do with it. I updated the firmware as directed by Elegoo. The problem continues. After all the back and forth, I decided to just buy a new motherboard, only to find out they aren't available anywhere. Frustrating. I'm glad that I didn't buy the plus and/or max as I planned to do. You cannot replace the motor drivers on the motherboard like on other brands. I have a Artillary and Flashforge that I have been happy with.
