Hi everyone, I am new here and new to 3D printing so I don't know anything. I bought a used printer and I'm having some difficulty with my machine. First what happened is this, the screen would be lite up but it would be blank, nothing showing on the screen. After some research I found that it more than likely is a short somewhere in the heater wiring and probably at the heater head. So I started moving it around it the screen lite up with letters again. Next I started taking it off and the belt came apart where the two ends connect. My question is this, there are two metal clips on the ends of the belt but how do I connect them back together? Is there some sort of clip that came off of it because I can not find out how it is suppose to attach together. The belt seems to be in good shape but if I can put it back together and get it going now I won't have to wait for a new one. Thank you for your help. Have a great! By the way, its the old Ender 3 3D printer.

Hi Roger, welcome to the forum!

On the original Ender 3, those two metal ends of the belt normally don’t connect to each other. Each end hooks into the carriage, with the belt running around the motor pulley and idler.

If you’re completely new to 3D printing, though, I wouldn’t recommend trying to repair a machine that may also have an electrical fault. It may be safer and less frustrating to return it if possible, or sell it as faulty/for parts on eBay and buy a working printer to learn on.
