LGT Longer LK5 Pro 3D Printer Upgraded with Dual Blower Kit, Large Print Size 11.8"x11.8"x15.7"(300x300x400mm), Open Source, Removable Lattice Glass Platform, Diagonal Rod and Resume Printing, DIY

I have had my Longer LK5 Pro for over two months, and I have over a kilogram of filament and about 200 hours of print time on it. I love it. This is my first 3D printer, but I am impressed with the LK5 Pro’s print quality, the large full color touchscreen, and how easy it was to set up. I consistently make parts with tolerances down to 1/10th of the millimeter. The machine is large! I could not find any dimensions of the unit, outside of the build volume, when I bought mine. It’s outside dimensions are approximately 24” deep x 20” wide x 26.25” high without a spool of filament, so plan accordingly. In sort, I would recommend the LK5 Pro to anyone as a first printer, for someone looking for a larger build volume, or as a general workhorse production printer. The long story: This is not going to replace any six-figure commercial printers, and I know the Longer is an Ender clone. The quality of the machine and its prints are very good. The 300mm X 300mm X 400 mm build volume is worth the extra money. I watched dozens and dozens of review videos, and I had none of the small fit and finish issues the reviewers reported. (They must have had early production printers?) All of my wheels and bearings were tight from the factory, and I have only made small adjustments after many hours of printing. I took my time and spent an hour squaring the final assembly and tramming the print bed with a feeler gauge (not with paper). I used the included filament to print the “Benchy” file included on the micro SD card the same night I opened the box. (Go ahead and order up a spool of filament because the sample is all that comes with the printer, and you will want to make a lot more stuff right away!) I made no adjustments and used the factory settings. The test print quality was impressive compared to most 3D printed things I’ve had experience with. Longer appears to be making improvements and upgrades as their team and users find them. The Maker community is also busy making upgraded parts to print, so I don’t feel like I’m alone with my printer choice. I find 3D Printing to be like any other hobby I’ve had. People are quick to join a “tribe” and declare anything other than what they have to be junk and a wast of time and money. Like any piece of equipment, there is fine tuning and experimentation to get it dialed in. Every filament is a little different and you will need to tune the printer accordingly in your slicer software. (That is part of the fun and how you work toward being and expert in something.) No tech gadget is truly plug and play or set it and forget it. In the end, do your home work and get something you like so you can make something! My personal experience tells me the Longer LK5 Pro was a very good choice and has opened up a whole world of design and production to me.

Purchased the Longer LK5 Pro 3D printer a few days ago and it came fast. It has been a dream to use. I would definitely recommend this as a great printer for anyone starting out with 3D printing or even for veterans that want a more compact and reliable unit for it's large size. I am extremely impressed. SET-UP. The setup was straight forward. It took me about half an hour to have it fully setup and powered on as they advertise it being about 90% already set up. Well it's true. All the tools needed are provided with the unit to complete the full setup. There are a few great youtube videos on setting up that you can watch as well if you need a little extra help. OPERATIONS. Very easy to use. This is not my first 3D printer, so I do have a little bit of experience with them in general. But this was still a very easy printer to simply start using. Leveled the bed, loaded filament and printed the test print. It came out absolutely flawless on this LK5 Pro. I am very impressed. Like I said, I have had it for a few months now and it has been rock solid. I have not had a single issue. Just load filament and print. I've not even had to re-level my bed yet. QUALITY. The unit itself is very sturdy. The hardware used is good quality. Everything aligns very well. I do not foresee any issues with quality in the future. They run multiple test before shipping it out to you Quality is top notch. VALUE. You will not find a better printer for this price. This printer exceeded my expectations on every level and the volume is just a added bonus.

I bought this to enlarge my pool of 3d printers and was pleasantly surprised I really like this machine. I'll do a rundown of both the pros and cons of this machine as there are many in both category I hope I have enough room in here! Pros Prints ok out of the box, if you tune if you'll get much better prints Nice large format Love the coated plate! this one works much better than the one's on my Anycubic's Comes with some decent clips to hold the plate, the last one I got came with the binder clips from hell. QUIET! Smooth movement, doesn't wiggle and rattle the table it's sitting on like my other ones do. SD card is easy to access, though could sure use some coloring around it to find it. I LOVE the large leveling knobs, FINALLY someone got smart Did I mention QUIET? the TMC2208 are just as quiet and the TMC2209's I'm building into a new system. Building the system was quick and easy, though knowing exactly what is an extra part in the instructions would have nice. Hand leveling was easier with the larger knobs, though takes going through each of the 4 spots a few times to get it right. The profile in Cura is cool with the LONGER on the plate, if I'm intending on printing something on a different machine it reminds me to switch to that profile. CONS System warms up S...L................O.........................W Filament loads S...L....O.........W Problems with filament sensor, Broke it on the 2nd print and the screw that attached it wouldn't come out. Had to talk to Customer Service to get the part replaced. Took well over a week to get the part and they still didn't send everything I needed. Power Switch is way in the back, would have been nice to move to the side where everything else is. Touch screen is not made for larger fingers No way to Calibrate the touch screen NO THUMBDRIVE port... sigh... most new boards have this feature added as most people have a million of those suckers lying around. When you cancel a print the head and bed cool down so quickly you have to wait for it to warm back up again. Might have to look at the marlin software and see if there was a setting for that in there and reflash the software. All in all, I'm happy I bought this system, I now have well over 300 hrs printing done on just this machine. As long as you know how to PID tune a machine I'd say get this, you won't be disappointed.

I've very recently purchased a Creality CR-10 V2 prior to the LK5-Pro and I felt it would be beneficial to some to give my comparison feedback. I had to return the CR-10, but this review isn't about that experience, and I'll try not to let it influence it. This is not my first printer, I'll mention that now. I wanted a another/larger printer. Box/Opening Thoughts: Both products are packaged very well, and look professional. Longer didn't have the tools as secured but that made no difference. I'll note that the CR-10 did weigh about 5lbs more, and I'll come back to that. Assembly: Both printers are some what assembled. CR-10 was easier to assemble, and instructions were easier to follow, more accurate images, written better. I had to watch a video briefly for the LK5 to clear up some confusion on a piece. Neither were difficult to assemble. In the past I've assembled kit printers, and either are a dream compared to that. Machine Itself: Both machines have same/similar parts. Both have "silent" drivers, which I believe are the TMC2208 but don't hold me to that. The glass beds appear exactly the same with different badging. They both have same hot end. The extruders are similar, I did think the Creality one seemed "beefer", but only slightly. I had less trouble getting filament through the "run out" sensor on LK5, and like where it's located better. The CR-10 has a stronger frame, which is where that extra weight comes in. It has a better looking hot end cover, and bigger fans. I'll also note the CR-10 has a slightly bigger power supply, and therefore heats up faster. The CR-10 also has duel Z, some people think this is a big deal, myself it's marginal. The LK5 Pro with it's attached touch screen is very nice, . There isn't a separate control unit taking up space and filled with fans that are very loud like the CR-10. This alone gives them some bonus points. Printing: Both printers printed pretty good right out of the box. There's always some tinkering needed but in this case I'll say it's a draw between them. The LK5 does vibrate a lot more when it's printing, but I'm sure I can dampen that with some TPU feet. Both printers connected to Octoprint with ease, and same with setting up a profile inside of Cura. Longer has profiles available. The Verdict: The LK5 Pro being over a $100 less than the CR-10 V2 makes it a clear winner. With the exception of the slightly stronger/heavier frame, dual Z, better looked hot end cover they are made of much of the same parts. I would recommend this to a friend.

This did not work right out of box. Sometime it works sometime it don't wont print with cura program only with the longer 1.3 don't want to print on bed runs off the edge, wont return to home replaced mainboard didn't seem to help would not recommend to anybody order another ELEGOO Neptune printer I have had great results with this printer.
