Looking for large 3D printer

[jeffmorris]

While I was printing some model car parts, the printer turned off by itself. I tried to turn it on several times but nothing happened. I checked the fuse using a test light and it was good. I took the bottom cover off and found out that one of the green terminals on the relay board (?) was burned out. I tested with a voltmeter and found out that the relay board (?) was not getting power. I temporarily disconnected the wires from the green terminals and connected them using butt connectors. I turned the printer on and I thought that it worked but when I started printing a job, the printer went crazy. How can I get the new part? I think that this forum won't accept images anymore.
