Im converting my bridgeport now. I have the x/y stepper mounts done ( size42) I have cad drawing for the mounts if your intrested.
I will be building the z axis drive for the quill next, and im working on an automatic tool changer.

How does such a stepper setup compare to a closed loop ballscrew setup like a prototrak?   Are you going to install preloaded ballscrews?

thanks,
Mike

Here's what I am talking about, it looks like this:



You put it in a collet and into the spindle, then look through the top window.  You see a crosshair in it magnified and simply move the table while looking through it to line the edge or corner of the part up with the crosshairs.  Because its under magnification, you can get it very accurately located, and quickly.

Hello,

I saw in a shop a black thing you could put in a collet and look through to find the edge of a part to high accuracy.  Anyone know where to get one of those?  I did a google search but didnt find anything.

Thanks,
Mike

Im looking on the main page of this site, scroll down a bit.  Theres a picture of a bridgeport style Sharp mill with a laptop connected to it.  I see that it has motor attachments that look similar to a prototrak.  Are those custom made?  Where can I get something like that?  I just bought a bridgeport and I am thinking of how I can convert it to CNC!
