Sorry about the shakiness. I came in and was told to make that video.

Yes, all units shipping now have a windows 8 tablet PC, which slides into a docking station that we print. We have replaced the motherboard with our own circuit board, which includes a power source for the tablet and some usb hubs, and a relay for the emergency stop.

If you mean the circuit boards on the print heads... we are more concerned with functionality and new technologies. We will eventually go back and design a cowling to cover the exposed workings... someday.

Thanks for the feedback, I will pass it along (you're not the first to suggest that the heads look unfinished).
