Somehow I missed that.

It's very charming, and I think even cuter than an SO1.

Next you'll need to help him make: http://www.cnczone.com/forums/diy-cnc-r ... ill-2.html

So...

When are you going to motorize that ShapeOko Jr. design?
As it is, the build's not even halfway one...

You can get steppers so small that they fit inside a Bic pen... So it shouldn't be too difficult to find some that fits in a 2x2 or larger LEGO brick.
(I'm an eBayoholic... I actually have that small steppers... )
And drag chains can be made out of lego tracks.
(Look for digger, bulldozer, snowmobile kits that has proper tracks)

These are 10mm diameter:

15x30 drag chains, custom spindle mount, 9mm belts, 8mm endplates, 6mm motor plates.

Ooooh, they come with pinions too! Can you buy compatible rack? :)

Those are PERFECT for a project of mine. Thanks.

The Pololu low-current DRV8824 drivers should work fine, I would guess. Saying that the information given by the seller is sparse is putting it mildly. Once I have them in hand, I'll be able to guess at what kind of voltage and current they expect. I plan to drive them with a linear audio amplifier anyway, for my application.

Haven't looked for a compatible rack, but I would be surprised if it doesn't exist on eBay...

Another, slightly larger motor is this one:

Should work nicely for a Z-axis...
