Hello,
I have a Solidoodle 4 3D-Printer and it has been working normally until now.
Everytime I connect to the printer via Pronterface or Repetier Host, everthing works for a minute or two. But then it stops and doesn't respond anymore. The only way I can get it to work again is cutting the power to the printer and reconnecting it.

Why does it alway stop to respond?
