We have a Fanuc RoboCut Alpha 1C wire EDM that will throw up a "reverse alarm" at beginning of any feed move. I know this is normally a short of some type, but I have no problem with the edge finder routine. If it was shorted, this also should not work. I have taken everything off and cleaned from the upper electrode pin to the lower electrode pin. It also will throw up the "reverse alarm" if you MDI "G0 G91 X1." with all 4 conditions on. Thanks for any help.
