Hey guys, as the title states, I had a fire on one of my 750's a couple weeks ago.

Started the machine in the mourning and aligned the axis and tool changer. Everything was fine. Started a tool change and the breaking resistor started to smoke. Hit the e-stop button just as the flames started to come out of the vent holes in the resistor box. A split second after I hit the estop the breaker that feeds my phase converter blew. Flames only lasted a few seconds, but the whole shop was filled with smoke.

Once the smoke cleared and I settled down, I had a look at the resistor. It was a bit dirty (I assume I burnt all the crud off) so I took it apart and cleaned it. Checked the resistance and it matched the label on it, so I put it all back together. turned the machine back on, and it booted up just fine. Hit the green button to enable the drives and got an error "Axis Drives Are Not Enabled"

Any ideas on what caused this, and what to do to repair the problem?
