What component did I kill?

Recommended Posts

When I was building up my second ultimaker, I was testing the fan 19v output with my multimeter and accidentally shorted the terminals. I heard a click, and everything was dead. I took the ardunio off, and that wasn't communicating with just a solid red light on it. So I installed a new Mega today, flashed firmware no problem. However, the ulticontroller screen is blank, with the backlight cycling between 3 brightness levels continuously. I try to run bed level wizard from cura, but says can establish connection. Any idea what the cause is? Or what I could have fried on the ultimaker board?

Thanks,

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
