I'm looking for some examples of high lead ballscrews with gear reduction in the Z axis.
When I say high lead, I mean anything over 13mm / rev.
Gear reduction could be planetary or belt driven.
Could be a commercial machine, a DIY machine, doesn't matter. Any kind of computer controlled machine with a high lead ballscrew and gear reduction in Z.
I'm just looking for any examples I can find please. Not sure if any exist.
