Yes, the original 775 also had a case short issue which we were fortunate not to run into. That issue was amplified by the overheating. We did fry at least three motors before finding the root cause of the overheating. Obviously since the OP was for 775pro, this case short will not be an issue, but overheating definitely will.

I did find the thread on the milling process. If you do a search for "cimulator cooling modification", we used the mod from J_Miles with great success - motors went from letting out magic smoke to warm to the touch.
