Hi All,

I have a Fanuc Wirecut EDM that has got too little program storage. I have a larger BMU board I'm getting ready to install. The system is a 6MC rev motherboard. I downloaded the parameters and pitch compensation. I'm wondering if there any hidden programs I need to download? I read that I may need to set a parameter to see any 9XXX or 8XXX programs. The current board is good, If I screw it up, is it just a matter of putting the old board back to get back to square 1? I will take a photo of the defect table before I install it as a reference. Anything I'm missing?

The process from what I read here and understand:

Back up programs and parameters (regular & pitch)
Write down (photograph) option parameters (1-6??) & RS232 parameters,
Photograph or write down defect table/s on BMU.
Power down and change board.
Set parameter write switch on motherboard.
Power on pressing BMU initialization buttons (have to look that up) E Stop on,
Input defect table/s.
Input Option parameters.
Input RS232 parameters.
Load parameters using RS232
??? Power down and turn parameters write switch off???
Restart and load programs.

Is this right? I don't want to screw this up.

Thank you

Roger
