But it's not as common as some other brands which means....not that many upgrades, tricks, tips are available for this printer. It also doesn't offer auto leveling bed but that's really not a big deal, once you get use to it you can level the bed in under 5 mins.I was pleasantly surprised, how easy it was to set up. I had to tune up some of the wheels and extruder assembly was wobbly a bit due to shipping but once all the wheels were moving freely and extruder assembly was not wobbly any more I was good to go. There is an eccentric nut under the extruder assembly that you tighten just a bit to make it nice and tight. Before printing something significant I printed 4 small cubes to test leveling or any other issues, with each cube print got better and better.This is my first printer, the video is off a vase printed at 50% this is first thing I did on a 3D printer it came out great, if you're looking for bang for your buck and familiarize yourself with 3D printing then don't go wasting money on expensive printers this one works great!!

Package: The printer is well protected.Assembly: The printer is very easy to assemble. It took me about 10 minutes to build the machine. The diagrams in the manual are confusing. Just use your common sense.Usability: The printer is well tuned. I use out of box settings to print the sample items in the SD card. The result is surprisingly good. No complaining on it.Problem: My biggest complainant is that the printer doesn't support auto leveling... It is a painful process to level the bed manually....Support: The Facebook group is very helpful and provide a lot of useful information.All in all, this printer can be perfect machine if it supports auto leveling.

From the get go my prints were bad, real bad layer lines, questionable adhesion, multiple failed prints, the list goes one. I literally wasted like 85% - 90% of the roll of filament that came with the machine trying to get it to work right and that's not even half my issues. About 2 or 3 months of printing, I needed a whole new hot end due to it getting so clogged that I wasn't even able to clean it out, and I didn't do that I wasn't supposed to do. After replacing the hot end, it was acting all screwed up to the point when I would start a new print I have to manually change the temp for the hot end to what it needed to be at just to have it print something. I recently printed 4 pieces about 3 days ago, the last piece failed, so when I try to print just that single piece that failed, I'm met with under extrusion and even more headaches. My video shows the gear starts skipping, at first I thought it was just the PTFE tube was clogged. So I bought a replacement. Same thing happened again. The piece I try printing is supposed to start off on a raft, the All I get are 2 and a half layers of smooth print before it turns into sandpaper. I'm done with this machine. I'm looking to sell it off for spare parts. The motors work just fine. It's just whatever isn't working properly doesn't make this unit worth keeping to use.

MAKE SURE TO UPDATE THE FIRMWARE BEFORE TESTING!!THE PAPER DIRECTONS ARE VERY BAD, GO TO LONGERS WEBSITE FOR MANUAL!!The instructions are vague and hard to see, yes hard to see. Once its put together and updated it does a fairly clean print. I'm just starting to do more complicated shapes and its nailed everything so far. The build quality is the only thing I can even kinda say is lacking. Some cord restraints are badly needed and the filiment spool holder could be upgraded to spin with the spool to avoid tension. Over all its worth the price and more because it makes prints that are in my opinion 95% shelf ready. Some light sanding is needed to make a perfectly smooth finish. I would buy again, for just under $200 I can't believe the results. Seriously though.... fix the paper instructions.

nothing works 'longer' than a couple days,.... unless you want to buy a new bed, extruder and feeder tube. Continuos bed leveling going on here and to add to the BS the mainboard shuts off all of the heat when you are bed leveling so then you have to wait ..................... to print and then it doesn't work.Anet A8 gets hotter and is more reliable.... prints it's own upgrades and is cheaper and more fun to work with.

En quince minutos estaba imprimiendo, tuve un pequeño problema con la impresora, me contacté con atención al cliente y obtuve respuesta pronta y precisa algo que se agradece, la atención fue excelente mi problema resuelto, motivo por el cual recomiendo al proveedor, para mis necesidades excelentes impresiones después de pequeños ajustes, en general muy contento con el producto.

Me llego sin el kit de herramientas y sin partes como el sensor z menos el conector de luz y demas no se que pasa pero el vendedor no se hace responsable y ahora solo estoy luchando porque me devuelvan mi dinero
