I'm running Colpey servo drives but I cannot get them tuned in with
LinuxCNC.
The servo is a current drive with a +- 10 volt input.
As there is not much load on the drive so a +-0.4 volt will swing the motor
at full speed.
The manual for the drive says to supply a stepped input to it and tune

Tuning with no load at all might be hard or impossible. Do you have the
motors attached to the ballscrew/machine?

Can you tell me what your PID values you have in your setup? I know mine
won't bet the same but it gives me an idea on the range.

Greetings all! My shift registers seem to be working well as a cheap
and easy port expander! Apologies for how long it took me to write it
up, but we are currently in the middle of the FIRST Robotics Challenge
build season, so I'm spending almost every evening mentoring high school
students.
You didn't mention if this was in AXIS or gladeVCP - but the answer could be
the same.
Since you are using a 5 axis machine with rotary axis there is an INI setting
to look at.
Under the [DISPLAY] heading
GEOMETRY=XYZA etc
Geometry sets how the backplot displays rotary movement.

Does anyone know where I can order just a few, I need 3, of the above bolt

The bearing blocks for this screw are machined only for socket head bolts,

them to properly
I'm having pretty good success with the 5i25/g540 setup - thanks to emails and
pointers on this list earlier.

Gene;
These are available locally, but I have a few steel 30mm, 40mm or a bunch of
50mm steel socket head cap screws. (Measured from under the head, not total
length, of course)
The 50mm ones - I have a whole bunch; just slightly under half the shank is
threaded. The 30 mm ones are fully

Yeah, Ace is pretty good for that sort of thing. They have all sorts of odd
fasteners, springs, o-rings and such. Way overpriced but a lifesaver when you
need a part in a hurry.

Hmmm. I'm in the San Francisco bay area. Hard to get further away from WV than
that. It did take like 5 days to get them though.

Yep, about $3 more to ship to a residential address vs.
