I can only speak for the "phantom" blade crash problem with
buildstation software (SLA500/30H, no zephyr) and the e-prom replacement.

The short-term fix without e-prom replacement is to reload 1.7.4
buildstation file cfab.exe to directory c:\slahome (I renamed the current
one "cfab.pre" to keep a copy of the way things used to be).

This defeats the "restart" build option, I think, among other things.
However, in the short term, you get to run the machine. I'm not sure this
works for 1.8 buildstation hangups.

When the e-prom was replaced, I deleted the 1.7.4 cfab.exe and replaced it
with the cfab.exe (conveniently renamed cfab.pre as noted above).

I recommend calling Dan Money , 3D Systems in Detriot(810-489-0200) for more
details about your specific situation (that's my "Hold Harmless"
disclaimer!!). I'd call him even if you have another 3D Systems district
service manager.

Good Luck
