Hello everyone. I recently picked up an Ender 3 and I'm having some issues. Mainly, the nozzle keeps hitting/dragging on the print. I replaced the print surface that was included with a glass one due to it bowing up in the center. A glass bed won't do that, will it? Leveled the print bed again, and started a print this evening. After an hour, the nozzle was really hitting the print as well as going to random locations on the print and driving itself into the print (that was a new one). As it got to the back corner, it pretty much decided that it didn't want to print what it was printing and started printing off to the side. This isn't the first time it's done that and I'd like to figure out what's causing it so I can hopefully fix it before it causes damage to the machine. It also doesn't seem to like printing anything over 3 or 4 inches in height. I've included a picture of the failed print so you can see what I'm talking about.
