I just installed a new hot end on my P1S and when I tried to start it back up I couldn’t get printer connected to my Bambu account. I reset back to factory settings and was doing a calibration and it wouldn’t finish the calibration. It went to the back left corner and stayed there for over an hour and a half. The only way I could get it to do anything was to shut it off.
I am a new user and have printed things for the last month or so. Some prints were looking sloppy so I replaced the hot end. I know I probably didn’t need to do that but I did.
