Review on 350X350X400mm Creality Ender 🖨️ Printer Screen for Additive Manufacturing Products by Matt Conner

I was really excited to put this together and print it and everything went almost perfectly for the first calibration print. Then I tried to do a second print and after about 10-15 minutes the printer just stopped pushing out the filament. After several attempts to resolve the issue (including increasing the nozzle temp, fully reloading the filament, and switching to a different filament), I finally turn to Facebook groups to see what I believe is the cause of the issue: It There is probably a gap/void between the nozzle and the tube bowden which allowed some of the filament to collect there and block the possibility of further advancement of the filament. So all I have to do is disassemble the extruder module to open the nozzle, open it and clean it. I've watched many YouTube videos to see the process and it looks very easy. First you need to unscrew the 2 screws that hold the fan cover in place. The head of the second screw breaks off on the first turn. So right now I spent a few hundred dollars on a very large paperweight because it won't print and I can't open the component to fix it. The first calibration print went very well and I was happy to use this printer for a long time. I'm still excited about that thought. But it's not working right now, and given the location of that screw between the fan shroud and the BL Touch sensor, I have no idea how I can even attempt to do the required maintenance without causing more damage.
