My laser doesn't have an adjustable Z table (you move the focus cone) and I'd like to add one to it. I'm looking for a Z table that can support around a 900 x 600 mm table. I'm making my own frame for it so external space isn't a big deal.
LightObject used to make one that would have worked, but they stopped producing it. Have any of you seen another off-the-shelf Z axis solution, or perhaps rigged up your own? I can certainly DIY it but I'd rather not invent the wheel if there is one I could buy or at least some plans I could follow.
