QIDI Technology X-one2 Single Extruder 3D Printer, Metal Frame Structure,Platform Heating

Works out of the box. I have had no problems with this printer. The only thing that I've noticed is that some people who review this have been having trouble unloading and reloading the filament. They really shouldn't. It's incredibly easy. I can load and unload filament in the first try in less that a minute every time. The only thing that might cause trouble is length of the feeding tube. It is barely long enough, but it IS long enough. If you push the feeding tube ALL THE WAY into the retainer at the back of the machine, the tube can "pop free" from the extruder when it has to reach the far corners of the build plate. It's pretty easy to solve, but I think some people are having trouble, and there is no mention of this issue in the instructions that came with the machine. So, I'm passing on the knowledge.Just push the feeding tube far enough so that it won't come loose (see pictures). Pushing it down all the way is completely unnecessary and can only cause problems. That should solve all feeding tube issues as far as I can tell. I've not had any trouble at all, and I've printed about 100 hours by now.If people are still having trouble loading and unloading filament then I don't know why. I can't figure out what's so difficult about it. It's about the same difficulty as loading ink into a 2d printer. Heat up the extruder to the recommended temperature for the filament and follow instructions and common sense. Loading filament shouldn't take more than a minute if you do it right.This is a great printer. Thanks QIDI for saving me assembly and maintenance time. My time is valuable, so I appreciate it.UPDATE 5/21/2019: QIDI still going strong! I'm updating this to help people in need of a fix for the feeding tube issue. After about 200 hours of printing, I have had the feeding tube pop out from the extruder occasionally on large prints that reach the far corner. Although relatively minor, the feeding to popping free from the back of the extruder can be annoying, so I 3d printed the minor fix you see in the attached pictures. I've posted these fixes at Thingverse and it is available to anyone who decides they need it. Just search for "QIDI feeding tube fix" and you'll find it. I've never had a single feeding tube issue since and it relieves a lot of stress put on the feeding tube as the extruder moves.I love this printer!UPDATE 3/15/2020:It's been almost a year since I ordered this printer and I've printed over a hundred objects. The print works as well today as it did brand new. Since I've had the printer I've replace the adhesive sticker on the bed after the old one got an air bubble (Qidi sent me a new one with no hassle for free). And I replaced the fan after I accidentally broke it with my Allen wrench whole unjamming a new brand of filament I was testing. I contacted Qidi knowing that my printer was out of warranty. Customer service was very nice and offered to sent me a replacement. All they asked was that I pay 9 USD for the shipping. They even sent me an instruction video link to help me even though I didn't request one. I will speak very highly of Qidi's customer service to anyone who asks. It's nice to know that they are willing to go above and beyond to help their customers.That being said, the printer is still very reliable. Once I have tested and understand the temperature and speed optimal for a particular brand and type of filament, jams are very rare. The only reason my printer jammed was because I was testing a new brand of filament I wasn't familiar with.I will also confirm that this printer can print with Nylon Carbon Fiber at max temperature with a hardened steel 0.4mm nozzle. I have done it many times with no jams or problems with the results.I maintain that this is a quality 3D printer backed by quality customer support at a reasonable price.

I bought the Qidi X-one2 back in March of 2019. That means I've been using it (almost daily) for 9 months. I would absolutely buy one again.Out of the box, it was easy to assemble and i was 3D printing within half hour. I made the test cube loaded on the SD card and then very quickly downloaded some fun models from Thingiverse. After that, I made a plethora of models that I downloaded and then started designing and printing my own.Here's what I like about it:1. The components are really good quality, especially for the price. It uses Nema 17 stepper motors and a direct drive extruder. Parts are readily available as this design is used by many Chinese manufacturers.2. It has a heated bed. The bed measures 150mm square and can be heated up to 110 degrees C. It is a machined aluminum bed with a PET adhesive sticker applied over top. The bed heats up quickly.3. The direct-drive extruder heats up to 250C and is easy to disassemble for maintenance. It uses stander M10 nozzles and replacements (including hardened ones) are readily available here on Amazon.4. It includes side panels and can be nearly fully enclosed. This is great for printing ABS or other high-temp filaments which need a stable temperature and no cooling. The side panels stick in place with magnets and they fit really well.5. The touch-screen display works well and the software is intuitive.6. It works with Cura and other third-party slicers.Here's what I don't:1. The PET sticker on the build plate doesn't last long and there is a mounting screw right in the middle of the build plate. That means that, as the sticker wears, you will end up with a divot in the center of the build platform which impacts print quality. The fix is simple: Remove the sticker, get a 150mm square sheet of glass and adhere it to the build plate with thermal tape. I did this and it's been a great print surface. Actually, I stuck a PET sticker back atop the glass and it's worked great!2. It doesn't print ABS well. Despite having panels to allow it to be enclosed, it doesn't print ABS plastic well. I've had a tough time getting ABS plastic parts to properly adhere and not warp. No that could be me, though, I also own a Qidi-1 and it prints ABS plastic beautifullyI've printed with several filaments and, with exception of ABS, this printer has printed well. That includes wood filament, PLA, carbon fiber PLA and ABS. I use a hardened nozzle and run the temperatures a bit higher. Print quality is good provided you get things set up right in your slicer.So there it is. Stop reading and buy it already. You won't regret it.
