Hello! I work at a library and a patron donated what I believe is a i3 Mega S printer. I booted it up but I’m getting a T0 sensor abnormal error. I also had a box with spare parts, including another hot end. I saw some people had success changing out the hot end but I didn’t. I’ve ensured all of the cables aren’t loose. I’m not too sure what else I can try. I’m still relatively new to 3D printing. My previous library had a Bambu that I was able to use and maintain for a few months. Any suggestions would be much appreciated!
