I know your goal is to tune with a scope. But if you messed with the
gain and dampening settings , rotate them counter clock wise. Note the
screwdriver slot edge at 7 o clock, then turn them clockwise to 10-11
for both. This is the factory setting that Marriss says works well. On
my machine I have the gain set a tad higher than the dampening. If you
can rotate the screw by hand, give it a quick twist and watch its
responce. You will see the same thing in the screw movement that you
will see with a scope. With the settings all the way off the responce
is pretty slow,easy to see. The trick though, scope or not, is how
quick of a responce do you want or need. High settings really stiffen
the machine, but can cause motor heating. Not to mention things get
noisier. I would say with high speed machining one would need stiff
settings, but for most of us the settings mentioned above are in the
ball park. To fine tune the relationship between gain and dampening a
scope would be the only way.
