Got some goodies from work. A couple linear slides. One set in a Cartesian arrangement with motors, drives, and a computer with a galil card to control it. It's a powerhouse, 25mhz 386!

The other two slides are basically the same. One has an animatics servo motor and drive setup. Kinda neat, it will take g-code drip fed into the serial port and drive the slide from that. It can also be programmed like an positioning drive. The other slide has a Reliance Electric servo and matching controller, a AB 1398-PDM-10. It has a positioning controller built in with a rack for IO. It will also work with step/dir pulses. I have another AB drive at home that can drive the motor too.

$100 for all of it. Have no clue what I am going to do with it all!

That's some big-time suckage right there!;)

(Lucky you.)

I not only don't know what to tell you to do with them --- I don't know what the Hell they are!

Yep, BIG TIME SUCKAGE! Nice table, too.
Have some of these positioners where I work. We use them for positioning soldering irons and feeders and terminal inserters - nothing very strenuous. Also for pick-and-place for unloading parts, picking and then sorting into good parts and rejects into various defect modes.

Let us know what you do with them.

That's some nice stuff.

The place I retired from was famous for tossing nice stuff in the dumpster. Once in the dumpster the employees could have it.
I saw nice stuff go the land fill only because I had no place to keep it at home. I still have a nice collection of DC motors and pneumatic components.

Nice score Macona.

You suck... How I wish I could get hold of some of those.......

Nice catch.

Looks like about half of a wire EDM to me.

I was going to suggest a 3D printer, but yeah, wire EDM could be done easily from those. Just needs some spacers to get the XY slide above the tank, a few plates and the arm that holds the wire guides and guide rollers, plus the electronics and a controller :)

If you want to tackle a project like this macona, I'm probably releasing the first version of my wire EDM controller soon I've written for the Arduino. Free and open source of course :)

Think they'd be sturdy enough for a cnc router? :confused:

The only 3d printer I would build is one of the light cured resin machines. I might be able to use the uv laser on my laser cutter to do that.

No too interested in edm, unless it was 4 axis!

Both of the long black slides use plastic nut lead screws with a 1" per turn ratio. That's not as bad as it seems. With the 1000 line encoder on the servo that still gives a resolution of .00025". Who knows what the accuracy is.

One thing that might be interesting to do with the setup on the stand is attach my camera and macro lens to it and do what this guy is doing:

You probably could make a small router with them. They are round rail linear bearing which I don't think are as rigid as rectangular rail linear bearings. The shorted units do have ball screws which is good.

Understandable :) My own machine has only 2 axis, but the controller can drive 4 axis too, just needs a few lines more to the G code interpreter, as I left some pins on the controller card free for just this purpose.
