TRONXY XY-2 PRO Titan 3D Printer, FDM All Metal 3D Printers Kit，Resume After Power Failure，Easy AssemblewithAutomatic Platform Leveling，UpgradedSilent Motherboard,Print Size 255x255x245mm

In the past year I've gone through 4 of these printers and all of them have failed because of various temp/sensor errors. Would not recommend, poor quality control.

Had high hopes when this printer arrived, but it had a few issues. The bed plate was a few millimeters too low. I replaced the springs with the manufacturer recommended replacement which also failed to work. I ended up purchasing 25mm springs and that fixed everything.Printing quality is pretty good for standard PLA. There have been a few failures with adhesion every so often which makes it difficult to determine the cause. The dual filament feature is nice and works without much issue.One downside is the size of the bed. Since its an usual size, its hard to find many choices for a metal plate or 3rd party suppliers.

This is my 2nd Tronxy XY-2Pro Titan. Grabbed this one on a lightning deal and couldn't be happier. Very solid machine. Will do a few upgrades but nothing crazy.

Received well packed, looked nice, but the x-axis limit switch was broken. Must happen routinely because they included an extra, so I replaced it. Set it up using manual and install videos. Carefully followed instructions for setup, calibration and leveling and the nozzle crashed into the PEI build plate and destroyed it before even a first print. I had some spare material so I cautiously started again making sure to set the z axis very high to prevent crash.The auto leveling is really assisted manual leveling. It doesn't work well and will only work with the included build surface which is likely to not last long. Then what? buy another build plate?? Not good.Tronxy software and firmware is buggy, will not display the thumbnail view as advertised, not at all even with the included example files.Customer support? LOL... Almost non-existent. They don't respond to email and if you are lucky enough to find them on their chat on their website, they are not helpful.You can't replace the factory firmware with Marlin or anything else so you are stuck. This could be a good printer but poor firmware, software and support make it a loser.

TronXY's reputation precedes them. This printer is just "ok."You'll get the most success with it if you go over every nut, bolt, roller, and extrusion. Mine came with the eccentric nuts hopelessly detuned so much so that the bed travel didn't even work correctly.

The media could not be loaded.  This is a good, but not great, printer.First, the positives:* It has a larger than average build surface of 255x255x 245mm.* It comes with a Titan dual-gear extruder (although it’s made of plastic). It worked very well with TPU on my test print.* It also has a form of rudimentary bed leveling system, although it’s not a true ABL. More of a bed leveling measurement system.* It is VERY easy to assemble, with only one ribbon cable, and one wire connector to hook up, and 4 bolts to insert and tighten. Took me maybe 10 minutes.* The control panel is a color touchscreen.* If you use the Tronxy-provided slicer, you get an image of your print on the screen.* The is a filament runout sensor.The negatives:* The Tronxy UI is confusing, at best, and the included manual did little to help out.* The SD card slot is in the back. Why would they do this?* The adjustment wheels for bed leveling are tiny.* Spring clips to hold the build surface to the heated bed are multi-colored. Just looks childish.* The bed springs are weak.* It seems the inlet to the extruder has an adaptor to allow for 2.85mm or 1.75mm filament, but whatever this black plastic cone is, it kept coming out whenever I changed filament. DON'T LOSE THIS!* They provided a flexible build plate and a greenish fiberglass plate, but didn’t say what to do with either of these. Turns out the fiberglas goes between the heated bed and the build surface, but I only learned this on the Tronxy FaceBook group.* There is no obvious way to adjust eSteps, zSteps, xSteps or ySteps. I believe you can if you flash Marlin into the machine.The filament roll holder is just a flat piece or metal. Not exactly smooth.Thoughts:The white elephant test print came out surprisingly well. I also printed out a blue TPU device to allow me to re-spool filament using a cordless drill, and I have to say, this is the best out-of-the-box TPU print I’ve ever done. I used the generic TPU (95A) material in Cura.I haven’t tried the Tronxy slicer, as I’m a long-time Cura user. Cura had a profile already available, and it worked well.This is a simple and elegant design, and for the money, it's a very good deal. I’m probably going to move to Marlin fairly quickly. I guess if I had never seen another printer I would learn the Tronxy UI, and it would be ok, but it seems too many things I need to do quickly aren’t obvious, and I need to get beyond learning the XY-2 and start using it ASAP.For the price, this is a good unit, and I recommend it.
