So, I bought a Black Box a few months back and have been successfully running X, Y and Z axis during testing. Since I'm building a plasma table, I put ferrite EMF shields on all wires yesterday (limit switches, motor wire, etc). This morning I fired everything up and none of the motors will turn. Normally when I power the system you can hear the motors 'lock' in position when they 1st get power but this morning...nothing. Jogging fails to do anything. Connection from either Openbuilds Control or Universal G-Code sender seems normal but nothing will power the motors. My question...would the EMF shields have anything to do with this or did the Black Box just go to 'Never-Never' land and installing EMF shields was just coincidental?
