Review on 🖨️ Enhanced Printing Experience with the Upgraded SUNLU 310X310X400Mm Printing Assembly by David Stewart

Background: I have 3 3D printers and have had an Ender 3 for 3 years and have disassembled and reassembled it several times. I wouldn't buy this printer again, but the reason goes a little deeper than the "first impression". Long story short, this thing took 4 prints and is now dead. The picture shows the thermal error I'm getting, so either the thermistor is already blown or the heating element isn't working. This printer worked fine. This is one of the easiest printers to build. The Plus version offers metal extruder parts and a filament runout sensor, along with a decent glass platform. I quickly lined it up and printed a test print and the first print came out smooth and had great adhesion. I understand why this particular printer gets so many good reviews. from the first buyers. The shock sensor is good, as is the glass bed. I managed to get good adhesion. Stepper drivers are terrible though. Even cheaper Creality printers opt for "quiet" stepper motors, which are basically an upgraded board that can drive the stepper motors smoothly so they don't hum. This thing is noisy and cheap steppers will affect print quality. There are also very odd decisions about things like cord placement and power button placement (you basically have to get under the side of the unit to get to the power button. That's the weirdest thing I've ever seen. The power cord is 5 Foot long ) . long, so buy a longer one if you decide to do this). The problems started when I tried to do something more advanced. The nozzle is 0.45mm in diameter, which is an odd size. Modern versions of Cura don't even offer this. And frankly, for large prints, a 0.6mm nozzle is much more effective. So I decided to change the injector. The first problem I had was that the size of the nozzle is not standard, it's a bit longer than the mk8 nozzles and to remove the nozzle you have to remove the fan cover. A NOTICE. This means that the fan shroud must be removed for EVERY nozzle change! If you don't do this, the metal on the bottom will spin freely and you won't be able to grab the heater block. So, part 2. When you try to remove the fan cover, the screws are too tight so the tools that came with the kit can't remove them and just start stripping. I had to get another set of tools from the garage to remove the screws. Once I did that I was able to remove the nozzle and replace it with a .6. Then when I went back to printing I checked my settings and alignment, printed the calibration cube and all went well. Then I did a longer 2 day print and after an hour I got an overheating error. If you don't know what it is, it means the heater block was ordered to keep "heating" and for some reason something broke and the machine crashed so as not to burn down your house. It's good that it worked, but you never want to see it. This indicates a malfunction of the thermistor or heating element. And since I've already made 3 prints, even after changing nozzles, that means they died after 4 prints. So now I have to send it back, disassemble, pack and send it back. An epic waste of my time.
