Ah, yes, 0.25 degrees doesn't look so huge.

So back to the original subject. It's not just motion that can cause a driver

I don't know what the industry standard is, but I can think of
arguments for leaving the drives

And as you can see, running errors allowed are fairly
large as I am not done tuning.
Geez, these don't protect you at all from something going wrong!
Here's the settings on my X axis :
FERROR = 0.003
MIN_FERROR =

Quick question.
There's a multi-axis operation in progress. For whatever reason one
of the servos throws out a fault and of course stops.
Should just the enables to the other servo drives be removed or should
power be cut to all

Gene,
If you aren't too far away to drive to Cleveland, these guys might be a good
place to ckeck out. HGR has all manor of junk to look at. Here is just one of
many options.

Totally off the EMC topic, but I had been having trouble

Greetngs Jon;
I am in the process of installing a newer machine to run that GO704.
But I cannot find a copy of boot.comp to build for the buster kernel.
Where can I pull another copy of it from?
Hmm, I have a copy of what looks to be the right

Hi Gene,
I always had an eye on the Rongfu RF-45. Here's one like it for a tad more

Greetings all;
My patience with the GO704 is about used up. I've the sheckles now to
replace it with something that might be better, and this one looks as if
it might scratch the itch. I'd like to get a bridgeport style but simply
do not have the room

What's the resolution of your spindle encoder and base period servo period?
There is no base thread on this servo system. The servo
thread runs at 1 KHz.
The spindle encoder uses the bull gear in the mill's head,
so it has 324 counts/rev.
