I need some help troubleshooting my print issues. A while back (months) I updated the firmware on my Elegoo Neptune 4 Pro. After I did that, I have not been able to get a quality print since. (I’m a teacher and a dad, so I just haven’t had many free moments to sit down and really work on it.) My worst issue is the Z axis on the calibration cube. X and Y are less egregious. Using Elegoo Rapid PLA+ and the same default settings I was using pre-update. Any advice would be helpful.
This looks to me like your part cooling fan is not turning on or pid calibration of the hotend is not good. Also may be over/under extrusion. You may need to go through calibration steps for your printer. It’s likely the firmware update cleared the calibration. There are many sites that will walk you through it, but I frequently use Teaching tech’s website: teachingtechyt.github.io
Also, white color is the worst for troubleshooting, literally any other color would do better. But even from that, I see your overhangs are drooping, suggesting too big temperature, over extrusion or no part cooling. Edit: corners also look overly rounded, so pressure advance is likely very off, too.
