Well, it happened. Luckily they are covering it under warranty. My Cel Robox 3D printer died, it won't communicated with the head. The feed keeps slipping. The thing starts up and shuts down intermittently, the last straw was the head began overheating out of control. They think it is the spring loaded connection pins and a sensor among other things that "apparently need to be upgraded since that printer was released".

I have enough printed out to begin assembly of the full sized head while I wait for the repair.
