PI P-915K238 XY Piezo stage
I picked some of these Piezo stages up on eBay. They appear to be an OEM design with ~15 microns of travel and I believe a 150v drive voltage. They’re obviously designed for some kind of optics application.
Here’s a video of it in action with the covers removed. The calipers are set at 0.5mm. I’m using a 0 to 150v square wave to drive the Y axis at 4Hz.

Hey there, I was thinking of ordering one of these from e-bay. What’s your experience been? Are used units somewhat resilient to wear (could one expect good accuracy from one of these years later) or are you finding lots of stage drift? Do you think its possible to hack together an arduino based controller?
Thanks
