you sent these to me in late December 2006.
Can you tell which rev. I have based on the date?
These are the rev A through C versions.
Rev D and E have this fix.
I would only add I gain at the end of tuning to keep static errors and errors
at low speeds to minimum. Enabling I gain early in tuning will only mask the
effects of the FF1 and FF2 tuning
OK, I will do some more tuning with only P-gain and try to get the FF1
and FF2 gains right.

Fun! Thanks for the link.

I think that's a great idea. I wouldn't even mind wearing a whole life vest,
with a little cord strapped to an E-Stop panel while at my machine :) I
could have used it today, while foolishly using the same variable for 'start
depth of cut,' and 'clearance height.' I was being lazy.

Hi Kirk
One needs to be just a bit careful about grounding these sorts of shielding --
if that is what's going on. I recommend star or single point grounding where
only one end of the shielding is connected to the frame. If you bond both ends
of power wire shielding you'll see ground loops

You could measure resistance across two phases, and compare with
resistance from one phase to the star point. (A needle poked through the
insulation is an alternative to ruining the neat job, if the pinhole is
insulated

Yes, Rev D started in Feb, 2006, so your amps are

you will need a high sample rate than used with velocity mode servos. A
a higher sample rate will allow higher P gains with these amps, improving
performance.

There's a ton of info on the board
At the request of a potential customer, I did some performance
tests with EMC2. I created a program with 1 blocks like
N123456 G01 F30 X1. Y0.

Each chord is roughly 0.0006 long. I ran it with the
