Troubleshooting Ender 3v2 Print Quality: Common Issues and How to Fix Them

Are you struggling with bad print quality on your Ender3v2? In this video, I go through the steps I took to diagnose and fix my own print quality issues. First, I tried changing the filament, but that didn't help. Then, I swapped the nozzle in case of a clog, but still no improvement. Finally, I decided to upgrade to a new aluminum extruder kit with a new extruder gear, and voila! My print quality was back to normal.

If you're dealing with similar issues, don't give up on your 3D printing dreams just yet. Join me in this troubleshooting journey and let's get to the root of the problem together.

Another good thing to check is the tip of your PTFE tube, where it meets the nozzle/heatbrake. I got similar signs of underextrusion, took the tube out and it was clearly deformed. Chopped it straight with a razor and the issue was resolved

I never thought to check the extruder gear, one of my enders has had some mild underextrusion issues lately, going to check that after work! Thanks.

Wow, I had litterly opent that extruder so many times. And when you talked about a crack i tought lets get the microscope maybe there is a crack but i cannot see it.

THERE WAS a crack. but the crack was so perfect it looked semeless. So becarefull maybe it looks fine! But if a haircrack is in it. It can also look like that.

This might be the problem I'm having with under extrusion, I first made the screw more tighter for the spring on the extruder motor and it seemed to work for a little while. Then I ran into an issue with under extrusion, again, which the issues look similar to what you are having with print quality.

I additionally have issue with my warped bed and I plan to install the latest version of Marlin to go with Manual Mesh Bed Leveling. I don't want to spend any more than I need to, so an auto leveler like a BLTouch would be later down the line for my purchases. Installing new firmware is rather new to me and I did see your video on it, though I'm still left with confusion in some areas despite how through you were with your video. For the most part, where I have confusion, mostly resides in the areas where you have glossed over certain details as you may of thought it was common knowledge on how to obtain certain information about the 3D printer.

Since I yet to go through with compiling and installing the firmware, I think I just have to go through the process to single out where I may lack information on how to complete the task.
