Yes, I am aware of this, it was pointed out to me after I got lowpass 
working on the minimill.  I just used the same constants I used from the 
minimill, it seems to work very nicely.  Since I already had the 
constant figured out, and was able to copy the code almost exactly from 
the minimill, that's what I did.  I probably will go back and revisit 
this again before going live.  But, still, lowpass is a lot better than 
just slamming the VFD from forward to reverse.
