Hot End Stress Testing and Prototype Building

This has been the week that everything is coming together.

First off, we used and abused the new hot end heater, even getting it up to 445C before killing it while putting 30V and over 3A of power through it. It took us three tries to kill it, taking it up over 400C a few times but having soldered connections melt or something similar.

The last few days have been getting the CNC parts panelized and test cutting them. And today we started the final prototype assembly with the casing looking pretty sharp, ready for the motion platform tomorrow.
