Re: [CAD_CAM_EDM_DRO] Gecko 2xx "Nema 42 modification"???

Hi Paul!

I see you've found your way over from the mill/drill list! Welcome!
You might also wish to take a look at the 4 axis driver I recently
built:

Sorry for yahoo's long URL! It's under "DRIVE P.." on the first page of
photos.

And could I suggest to our pix posters, It might be a nice idea to put
multiple pix on a subject or from a contributor under a "album". Simply
create an album first, select the album, and then post into the album.
EASY!

Nice pix Peter!

P.S. and thanks to ALL our recent contributors! Nice PIX GUYS!
