the eliptical bearing is nice, but you can get away with a diametrically

No, diametrically opposed rollers is bad idea. Rollers

I use ngcgui and just fill in the blanks for length of cut. I have one
called x-trim that I just need speed and length and off I go.
Before ngcgui I just used a file called x-trim.ngc and edited the X and F.

Did you get a chance to look at the scope traces?
I've secured a rather large 3 phase generator and power unit and will be
hooking it up over the next few days for further testing.

Yes. It appears that the Reactor is performing some useful function by
removing a lot of noise.
I'd go for the generator and see what happens.

Hi,
Google is sometimes not my friend. Grump for an older guy. ;-)
The idea is to install a linux from a live cd to at usb so I can get it
on a D510MO. Since this board has no ide the route I think makes sense
is:
Download live iso from .ro site (done)
Transfer iso to bootable usb.
Boot from usb
I recently did this successfully, albeit from a windows machine. I used
Linux Live USB creator (http://www.linuxliveusb.com/), pointed it to the
iso, and it made the USB stick bootable w/ the CD image. It doesn't just
copy files.
You should be able to use Unetbootin from the linux command line

You should be able to use the Linuxcnc LiveCD as the ISO image.
Failing that, install generic Ubuntu 10.04 to the USB, use it to install,

That's what I ended up doing. In my case I was trying to make a bootable usb
on a Mac. Tried 3 - 4 different usb sticks without success.
First time I ran through the process on an older Win2000 machine, everything
worked exactly as it should. Now that particular USB is tucked away as the
Perry Mason would say.
