I got a "Gene Machines OmniGrid 100" at an auction earlier this year, its a
microarrayer, a piece of medical equipment, its made just like a CNC machine,
when I got it, the gantry and X axis were just piled lose into the plexiglass
enclosure, no computer and no table, just sitting on a pallet, I was told that
in another week or two it would have been scraped, sold for scrap metal.

I did get the controller box with power supply and servo motor drivers,
but was unable to get the computer or the rolling table the unit comes with.




Here is a list of parts I got with the unit.

The servo motors are:

X and Y axis motors = SM232BE-N10N - Peak Torque of 334 oz-in, weighs 3lbs
Z axis motor = CM162AE-01086

The rails are:

X and Y axis rails = 404600XRMS - they have a working length of 600mm / 23.622047in
Z axis rail = 404100XRMS - has a working length of 100mm / 3.937008in

The power supply is:

Astec 800w power supply, 60V @ 12A, 24V @ 4A, 5V @ 10A

The servo drivers are:

(x 3) OEM670T Torque Servo Drives

And lots of small pieces of T-slotted aluminum profile 1x1 inch, and various
related T-slotted aluminum profile hardware that went into the making the
OmniGrid's Plexiglas enclosure, the enclosure was so huge I had to dissemble it.


I was thinking of replacing the servos and drivers, with three KL-8060 Drivers
and three KL23H2100-35-4B stepper motors, and reusing the 60V power supply, I was
also thinking about putting the gantry on 20mm SBR Supported Linear Rails and
increasing the CNC size from around 24x30 inch to something like 24x48+, and I
was going to use a 1/2-10 five start lead screw to move the gantry, any ideas?


I posted some more info some time ago in this post made by someone else
who also got one.

Here are two Youtube videos of an OmniGrid 100 being used.
