There’s been a lull (partly due to my becoming a parent, partly due to summertime/school opening blues) in work on the rapid prototyping system. It turns out that this was a blessing in disguise because I recently got my hands on something that will make this project a significantly different scope.
My company threw out an old solder paste inspection machine. It WAS a machine intended for use inspect printed circuit boards after they’ve had the solder paste applied to them but before they’ve had components placed. As far as I know, it is in full working order.
In short, this is a working X-Y gantry with sub-millimeter accuracy. It does have SOME Z motion, too, but not much- I’d guess in the end we can adjust the limits and get something along the order of one inch in Z.
For a platform to build a prototyper, you can’t get much better than this. And it’s in my garage.
See the forum thread for further details or schedule changes.
