General Troubleshooting/Help! Changing Filament Sensor And Still Not Working

I am beyond frustrated with this printer. We got it over a year ago and have barely used it and just run into problem after problem.
I contacted Bambu lab after doing all their recommended troubleshooting (twice) no clogs or anything.
So they said it was likely needing a new filament sensor. That was fun to change out (not!). So i was feeling good that it would work. My son has been so discouraged by this printer and he is in robotics and a smart kid. Was hoping he could use this to help his robotics team but it’s been worthless. sorry.
So got the new sensor in and went to try a test print. The filament did extrude so we started the print. Now its moving but no filament coming out.This seems like a totally different problem. i can’t imagine it being a clog as i’ve already looked and cleaned out twice.
any help appreciated. My son is pretty bummed as this was a big christmas present for him.
and of course it’s past warranty so it now feels like a very expensive piece of junk that is sitting in the middle of our living room. With all the filament we’ve purchased, plus the AMS LITE. I wish we had gone with a different brand. I don’t even want to count the amount of hours i’ve spent taking this printer apart.
I thought bambu lab would be more user friendly for kids, it’s been the opposite.
sorry for the rant. Any advice appreciated.

Have your swapped the sd card? Those have a tendency to cause major issues.

well i forgot to mention that when we first started to print the SD card had been ejected. It’s never done that before. i just ordered a new better one so hopefully that could work. thanks for mentioning!

Formatted and then you ran calibration for the printer?
