    • Best large format printer at it's price point, but not for beginners...
Size: Neptune 4 Plus
First thing's first - the print quality and build size of this printer is excellent. There is no layer shifting, the printer is quiet, the speed is unbelievable, and the huge build plate makes it a breeze to print that cosplay helmet you've always wanted, or every part of that Thingverse toy in one shot. BUT... the journey to get to that quality is not for parents looking to get their kids into 3D printing for the first time, or anyone who isn't comfortable getting hands-on. If you want that, get an Ender or equivalent. This printer does not "just work" out of the box. Not even close. There's a pre-flight checklist that needs to be done before attempting a first print, then another checklist to do before subsequent prints. There may be a few more things to check, but here are the items I checked prior to my first print (which was flawless only AFTER the checklist). I'm making a review and not a guide, and there are dozens of videos and forums that will step you through the problems/fixes. Nothing below is complicated to fix, but they must be addressed prior to printing: 1. Are the screws on the z-arm tight? Nope. Mine weren't even finger tight. 2. Is the z-arm level? Nope. My left side was 1mm off. It might seem like nothing, but 1mm is 10 layer lines - a disparity like that is huge. Yes, the auto leveling somewhat compensates, but why force the printer to adjust for something so easily remedied? 3. Are the wheels on left and right of the z-arm properly tensioned? Mine were just OK, but some adjustment was still needed. 4. Is the voltage set to 110v if you're in the USA? Almost certainly not. You'll know if yours are incorrect because the bed LEDs will look like a light show at a rave as soon as the bed heater turns on. 5. Is the bed loose? Mine wasn't, but many are. Simple fix (sort of) 6. Is the bed level? Not from the factory it's not. Not even close. Set your z-axis adjustment, then go into the manual setting and set the 6 bed level screws... TWICE. Then check the z-axis one more time and you're good. 7. Is the bed clean? Just wipe the bed down with IPA and you're fine. The community has opinions on this - just use the IPA. No need to wash the damn thing in the sink every time. 8. There is test filament in the nozzle - be aware and run decent amount of your new filament through the extruder before starting your first print. 9. DO heat the bed up a print temp for a minimum of 20-30 minutes before printing. The large bed needs time to thermally adjust/swell before it's level across the entire surface. 10. Ditch that dated Cura slicer and upgrade to Orca. The Neptune 4 Plus profile is almost dead-on. 11. I would HIGHLY recommend turning down the jerk/acceleration on this printer. I set mine to half of the recommended settings. Yes, you'll lose some speed, but at least you won't have the print head flying around the bed, knocking off supports and delicate parts from your print. This printer can be a bit TOO fast at times, and there is often a direct (negative) correlation between speed and quality. Rookies see a peak 500 mm/sec speed and think this will be their new norm, but it's not. That kind of speed is limited to VERY specific applications/filaments. On a related note, cheap PLA can be printed at 200 mm/sec, but it's not ideal. Get PLA designed for higher speeds if you want to do it right. 12. Lastly, if you're printing anything more exotic than vanilla PLA, consider leaving that giant z-axis fan OFF. Yes, your layers need a few seconds to cool, but that fan will cause odd shrinking and adhesion issues if you're not careful. Don't think you need to use it simply because it's there. Pre-flight checklist is done! Your first print is amazing! BUT your second print is a mess. What happened? 1. Again - preheat the bed EVERY time you start printing a new batch, 20-30 minutes minimum. 2. I would highly recommend re-leveling the bed prior to each print session. If nothing else, check your initial z-axis clearance, then auto-level the bed, then print. Yes, it's a hassle. But it's the price you pay for such a large print surface. That 10 minutes of work will stop your print nozzle from dragging across printed areas, tearing off supports, or providing weak layer adhesion. Buy this printer. But understand that a few hours will go into the assembly and setup. Then a little time needs to be spent prior to each print. Follow those rules and you'll be extremely happy with this printer. ... show more

    • Reliable, user friendly, but loud
Size: Neptune 4
Review Image by C. He C. He

It does its job well. The bed leveling process isn't too hard, but it is not fully automatic. There are a few manual steps to get the nozzle at the correct height at the center and near the 4 corners. Then it automatically does a more detailed map throughout the bed. The four adjustment knobs for the four corners are rather easy to turn, without a way to lock them in place, so over time they will likely drift and have to be readjusted. You want to do a bed leveling every time things may have changed such as if you've moved the printer, you have done a number of prints, or it has been some time (like several days) since your last print just to be safe. I once tried to pause a print and then move the printer, but after resuming, the print fell apart, and the printer was basically extruding spaghetti. So I would say it is best practice to let an entire print run undisturbed. I would have the same patience for this printer as I would a washing machine, rather than a paper printer. It is loud, particularly the fan that cools each layer. On top of the smell, it is not suitable to keep and run in my small room. I was even worried about the noise disturbing my neighbors when putting the 3D printer in the living room, so I moved it to our laundry room. This is my biggest complaint for this printer. I also would have liked the holder for the filament spool to be more sturdy. For the most part, it is user friendly. You just need to follow a video to set it up. Then you have to learn about the best print settings for making your .gcode files the included Cura software. I decided to have most of my prints set to 0.2 mm layer height, 20% cubic subdivision infill with supports and brim. The parts that I print tend to have small features of a few mm, so those areas will be nearly 100% infill due to the 3-layer shell. I have yet to run the printer at 500 mm/s. A typical speed is more like 200 mm/s, and the prints more complex parts that are a few inches in size and about 30 grams in 1 hour, whereas smaller simpler parts like 1/2" cylindrical spacers or small gears are done in 10 minutes. Hole diameters are not always accurate to 0.2 mm, and may be off (usually smaller) by as much as 0.5 mm. If it's a small enough hole, then I easily solve this by using a drill bit. I was able to do this for holes as small as 1 mm, but should be possible for even smaller holes. For larger holes, I have tried filing, sanding, using a deburring tool, and even a knife, but this is more labor intensive is easier to just reprint the part. Any hole whose axis of symmetry is horizontally-oriented will turn out to be more of an ellipse, and the supports take some effort to get out. If you're making smaller parts like me, such as mounts for PCBs or gears and adapters for micro servos, then I would recommend getting a set of M1.7 to M3 self tapping screws, as those have proved invaluable for assembly, although you have to be careful not to tighten too much and strip the hole you tap. ... show more

    • Truly a great value
Size: Neptune 4
I am replacing and ender 3 with this neptune 4 & I must say, it really is a nice bit of kit for the price. Print speeds are FAST. So far I've been able to get decent quality prints even when running the infill @ 250mm/s & the outside wall @ 100mm/s. It seems to handle first layer speeds of 100mm/s as well. Lastely the klipper firmware & interface is a really nice feature to have. I don't think I can go back. Now it doesn't have all the bells, for example internet is ethernet not wifi but really my expectations were exceeded at the price point Update: The printer no longer seems to boot correctly saying it can't connect and when it does boot it no longer seems to read any files from SD card or USB. Not really sure what to think at this point but now it's Essentially a boat anchor. Will update if the situation changes. Update: elegoo support quickly solved the issue and sent new firmware update with clear instructions. The printer is working great again. UPDATE AGAIN.... The machine lost zero and crashed hard, at first i thought maybe this was my mistake but it was quickly followed by the printer firmware failing and refusing to connect thus making this again a boat anchor. at this point i have more than 20hrs of my time trying to make this pile of crap work. Really its a shame as it seems like it would have been a great printer minus these glaring problems. ... show more
