Try looking for a Nema 48 AC motor. They are almost an inch smaller in
diameter.
Also, there are some metric frame motors that are common in Europe that

I re-controlled one of those in the past but we simply rotated the part
around the Z axis as the part moved downward through the coil in the Z
direction.
But then all of our parts were round.
Its a really quick way to heat treat a part!

Andy is right. Bag the 5V power supply and do a port steal from the
USB port for a 5V supply.
You can get nice tight twisted wire pairs from a Cat 5 patch cable.

The Animatics motors are an all in one Servo motor/drive/interface all
stuffed into a very small package. So there is no separate boards or
amps for these motors.
They are nice, but pricy.
Moog bought out Animatics a while back and Moog is not known for low
priced anything!

I have driven IM483 drives with LinuxCNC using a D525MW board and I
didn't have any issues at all.
I did use a breakout board to do that though.So I suspect that your
breakout board is faulty or you have some other wiring issues.
I've used the previous version of the C10 board and that it wo

They can be controlled in different manners.
VFDs and AC servo drives oftentimes create noise on the incoming AC
power lines to the drives.That noise can cause interference issues
with system electronics.
I recommend you purchase an incoming line filter to keep the noise from
backing up into your AC power line.
This is a filter I use

I don't recall that ever being mentioned on the EMC2/LinuxCNC email list?
Where is it at??

I think that something like that would be custom made to suit the

A spring steel rod properly tempered, etc.
If you have any heat treatment shops around you they may be able to make
some suggestions. The spring shaft might have to be quite long to get

Trademarking doesn't do much other than allowing someone/thing to take
some ownership of a name to make sure that someone else can't openly use
the same "name".
Remember when EMC2 became LinuxCNC? That was due to what EMC saw as a

Those connectors are cheap! But I would be hesitant to use them for
stepper connections on a machine that you need to trust. If you get a
bad connection it can take out your stepper driver.
Amphenol and others sells round plastic connectors for not that much.
Check out Digikey, Allied, etc

Remember the email list conversations that Rob and you had with the
Mach3 crew a while back?
That now puts those conversations in an entirely different light.
If you want a great discount on a slant back lathe or small mill, now

I think you can do what you are talking about with LinuxCNC and some HAL
work. But apparently no one on this list has actually done that.
