XY Table

cults3d

I made this for my brother so he can have sensors or equipment navigate over a microwell plate, which you can learn more about at http://en.wikipedia.org/wiki/Microtiter_plate. It might not be super useful to anyone else, but I'm sharing it here just in case someone is interested. I added the SketchUp model for any parts that I missed on the STL files, so use that to extract the pieces you need. I didn't go into a full assembly description, but if you want more details, check out this post at LMR - it also has a video: http://letsmakerobots.com/node/31381. UPDATE: Just now, I got some information about the 28BYJ-48 steppers that I used, and unfortunately, they're not reliable for high accuracy. So if you're trying to build an XY table with sub-mm precision, you might want to look into other stepper motors instead. Here's the info I found: http://arduino.cc/forum/index.php/topic,71964.0.html
