I exported some fff files because I had to do a reset all files because my S3D was crashing. I was surprised to learn the fff files don't appear to really store all of the process information, but instead seem to be some sort of placeholder and you must load a factory file which will access the fff file to recreate the full profile. Everything for startup codes to even nozzle diameter would not load until I loaded a previously save factory file that used the appropriate process.
Bizarre file handling in S3D. Always been my main complaint with the software.
