That may suggest a couple of things being wrong simultaneously:
1) you may still have loops in

Do you have filters just prior to the input power on the AB Servo drives?
I've also had problems with Teco servo drives backfeeding noise into the
AC line and messing with Mesa boards.
An input filter from AD fixed that problem as well.

I tried to find the original message in previous monster thread to have
a better understanding of the problem but could not find it. I can't
remember seeing what is connecting to VFD and few other things. I assume
it's a Mesa board but which one? [1]
We all seem to keep running in circles here.
Hmm.. perhaps you should tell Peter that Missouri is wonderful this time
of year.
Perhaps he will schedule a flight to the "show me state". :-)

LinuxCNC 2.6.12 has been released. This release fixes a couple of
relatively obscure bugs. All 2.6 users are encouraged to upgrade.
Credit for this release goes to all the folks who have reported bugs
in our code and documentation, and especially to the people who have
committed bugfixes and imp
I understand.I'm working out of town and just came back for the
weekend.
For me this is a good time to be distracted with too much work.
It helps me ignore the wind gusts to 30 mph, the snow, and the temps
headed to 8 degrees F for tonight.
Except that I need to drive a long ways in this cr

For step-dir and encoders the normal recomendation would be the 5i25
or 6i25 and then a 7i85S for the step/dir and encoder interface.

The video here was very informative, showing how a small gear motor and
a windshield wiper motor can be converted to servo motors. It also
covers things like positioning accuracy and shows a motor from a printer
with a very high count encoder disk.
