Did you use that directly with ExpressPCB and order from ExpressPCB or
did you convert to more standard gerbers? (This thread has me
motiviated to maybe get my 11/45 running again next year, and verify or

[Note, I have also been corresponding with the OP on purchase of my 4
"spare" boards for an FP11-C]
