Second Board...dead...or is it?...What's happening? Please help.

Posted · Second Board...dead...or is it?...What's happening? Please help.

I have a scratch built ultimaker. It's been working great. I love it. But now for the second time, the first time I wrote off as a bad part, the front screen stops working and the whole machine seems to die. I've attached a video. When I disconnect EXP 1, the printer seems to come back to life, but I'm not sure what the actual problem is. I've been running tinker's firmware, but it's been working great since I completed the build at the beginning of the summer, around May.

Has anyone seen this?

After printing non-stop all day, I took a break to talk to the missus. I turned the machine off. When I turned it back on, thirty minutes later, the machine turns on to silence and a repeating click, as if one of the steppers is trying to move. The screen doesn't come on, nor do the lights.

 

Disconnecting exp1 seems to fix the problem, I suppose, but the machine of course cannot be controlled then.

I tried connecting via mattercontrol, hoping to control the printer without the screen. This seems to work, but I am not really comfortable with it. Is the front board dead?
