I wanted to ride my bed at 110 ° for the abs but I've realized that the connection on the map melzi mother broke down. So I removed the connector and connected live + and - on the motherboard. When I plug the current component on the photo heats quickly and weld crackling, I think that the component is dead because I note the resistance is different than the hot end. If anyone can help me, I think I have to replace the pointed component, maybe. I also noted that the hot bed of resistance 103 does not have the same value as that of the heater head and fans also should replace? I want to say that the printer is under warranty but but request from the Chinese dealer have so far without success. It's disgusting.
