Don,

good thing you kept the .ini and .hal files - reminds me to make backups 
once again cause I think I changed the files since the last backup ...
I copied my working config for the mill to 3 different machines (one 
active, one backup and one to play with at home) by comparing a setup 
generated by stepconf and changing the proper timing and addresses.
Still, remember that the jitter, although it is an exact number, depends 
on what you do with the machine at a given moment and therefor is just a 
guidance number.
At least this is how I see it: start the test, do all kinds of weird 
stuff that keeps the computer busy and get the worst number. In that 
case you will most likely never hit the edge in real life.
But then, when the mill is running I never do all this weird stuff. This 
is a production machine and  when it runs I do not touch mouse or keyboard.

A 10% difference in jitter value is not that big. I've seen differences 
like this on different occasions that I ran the jitter test (on the same 
machine with the same software - no updates in between).

This does bring up a new question: Can (will) the jitter test report 
different values after a software update? Since I configured my machine 
more than one year ago there have been some updates (I'd even say my 
EMC2 PC is more up to date than any of my windows machines).

Rob - almost ashamed to admit still using Wingoof XP ;-)
